Questions after receiving my latex mattress

Hello,

Note: this is not a review. I’m new to latex and hoping that this mattress is going to work out for me. Looking for feedback.

I purchased a mattress from MFC after months and months of research.

My memory foam mattress is 8 years old and began sagging this past year.

I’m new to latex and didn’t know what to expect. But after reading so many good reviews about latex, and bad reviews about all of the brands I could try in a store, I took the plunge.

From what I read it seems like people consider latex pretty firm. Searching on Google states that latex pushes back against your weight and has little motion transfer. I also read that organic latex does not off gas, but the mattress has a strong odor (anyone know how long before the smell goes away?).

I reached out to MFC for assistance in selecting a mattress with good support for my back. I purchased what they suggested (Cumulus, coils with two layers of latex).

After unboxing and laying on my new latex mattress, I quickly realized it was very different from memory foam. When I am on my hands and knees climbing onto it, my hands and knees immediately dip. When I laid down it immediately sinks where my hips are. I’m talking several inches of sinking, so that my spine is curved. I’m not sensing any push-back against my weight(I’m around 125lbs). I would not call it firm at all, more like extremely plush. And when I move the whole mattress moves. Lots of motion transfer. If I lay on my side I feel like I’m rolling forward onto my stomach as there is not enough firmness to hold me on my side. Is this normal with latex?

I rolled over to my old memory foam mattress that’d been saggy and it feels extra firm in comparison.

I’d appreciate any feedback from others who made the switch to latex and whether they were able to get used to it. Also anyone who has back, hip, neck pain, how was your experience with latex?

Hello Onyx!

I’ll tag @MFC here just in case you haven’t already reached out with your concerns, but how long was the mattress unboxed before you laid on it?

Hi Onyx, welcome to the community, and thank you for sharing your experience.

It’s completely understandable to feel a bit unsettled after your first night on a new mattress, especially when switching to a material like latex, which can feel very different from what you’re used to.

My response isn’t to suggest that a mattress is the same as a pair of glasses or running shoes, but there are some helpful parallels. When someone gets a new pair of glasses with a slightly different prescription, or a new pair of running shoes that haven’t yet conformed to their feet, there’s often an adjustment period.

Similarly, transitioning to a new mattress, particularly one made from different materials or with a different firmness level, often requires time for both your body and your expectations to recalibrate.

Latex behaves very differently from memory foam. It’s more buoyant and responsive, and rather than allowing you to sink in and conform like memory foam does, it offers surface-level support. That “pushback” sensation people refer to doesn’t always feel like traditional firmness, especially at first. At 125 lbs, your experience of plushness may be more noticeable initially, but it doesn’t necessarily mean the mattress lacks proper support ,it may just feel unfamiliar.

It’s also worth considering that your foundation plays a big role in how the mattress performs. The type of base you’re using, whether it’s slatted, solid, or box spring, can influence the feel of latex significantly. If the foundation has too much give, it can exaggerate any feeling of softness.

As for the odor you noticed, that’s common with natural latex, and although it’s not off-gassing like synthetic foams, the natural rubber scent can still be strong at first. This typically fades within a few days to a couple of weeks depending on airflow and room conditions.

MFC is generally very helpful with post-purchase support, and it’s not uncommon for customers to need minor tweaks to dial in the right feel. Some people adjust without any changes, while others work with MFC to modify their setup. Either way, it often takes several weeks, sometimes even a couple of months, for your body to fully adjust and for the mattress to settle into its performance characteristics.

To be frank, whether right or wrong, comfortable or not, your judgment seems a bit hasty. While you’re certainly entitled to your perspective, it may not fully reflect the broader context of the situation. If your experience doesn’t improve after some time, you might consider reaching out to MFC for guidance. You’re not alone in feeling this way early on, many people find that, with a little patience and sometimes a few adjustments, a latex mattress can turn into a long-term source of comfort and support.

Hope this helps,

Maverick

Thank you for this very thorough reply!

The information you provided is very helpful.

I think there was a knowledge gap for me regarding initial impression/expectations as this is not like any other mattress I’ve used. I just needed to know that this was normal.

I did reach out to MFC and they got back to me promptly and let me know it could take about a month to get used to.

You’re correct, I was hasty, I have very bad back, neck and hip pain and have not a had a good night sleep in years. I’ve been very excited to get this mattress in hopes of finally feeling rested. I’m hopeful this will finally help me get a good night sleep and help with my pain.

Oh, I didn’t realize you were already in contact with MFC, that makes sense. They’re known for being very responsive and committed to customer satisfaction, so it’s no surprise they got back to you quickly.

I can really relate to your concerns. Having dealt with multiple herniated discs myself, I understand how important and elusive a good night’s sleep can feel. I recently tried a two of the new pillows from European Sleep Works, and even something as simple as a pillow came with a learning curve. The Oxygen Pillow, in particular, is quite unique in design and took some getting used to. That adjustment period reminded me how even small changes can require time, especially when dealing with ongoing physical issues.

In my case, the two different pillow designs actually supported different stages of my recovery, depending on where I was in physical therapy. So I completely get where you’re coming from.

Try not to get discouraged. After about a month on the new mattress, we’ll have a much better sense of whether any fine-tuning is needed, or you just may have found yourself finally getting that comfortable sleep you’ve been hoping for.

All the best,

Maverick

Yes I’m starting to realize that the tiniest adjustments have a huge effect on my pain.

I’m considering trying to teach myself to sleep on my back with a pillow under my knees (I’m a side sleeper and move around a lot in my sleep, so I can’t keep a pillow between my knees).

I also got two free latex pillows with my MFC mattress, and though I can’t use them yet because of the smell, when I tried them out, the shredded latex pillow seemed very promising. I’m excited for the smell to dissipate so I can try it out. It seems to have the perfect amount of support.

Give it time. You might end up needing a two inch topper to customize it.

I sleep on 9" of latex. I weigh 115 lbs, not that much less than you, and I have back pain. I sleep on Soft/Medium/Firm. I get a lot of push-back against my weight. I looked up the mattress you bought and it has 2 2" layers on top of springs. I’m guessing the sogginess might be from the springs? I’m not sure 4" of latex is really the same feel as an all latex mattress. I saw that your lawyers are soft and medium-- have you tried switching so the medium is on top? that might help.

Hi. Thanks for your input. I’m starting to fear that it is the springs that are the problem, but MFC’s exchange policy doesn’t seem to cover springs.

And yes I currently have the medium layer on top.

Onyx, you might be right! Although I haven’t looked at their policy. But before making any final decisions, always talk things through with MFC or whoever you’re working with. Let them know what you’re trying to do, where you want to go, and what you’re hoping to get out of it. People like MFC are there to help and have your best interests in mind.

Having said hat, nobody likes surprises popping up later on, or the “you never told me stuff.” If everyone’s clear from the start, and the parties involved understand each others goals and motivations, they might even be able to make accommodation a bit to fit your situation.

Hope these words of wisdom help.

Hi Onyx,

Coils can compress approximately 1" to 2" depending on the layers that are placed over them, the weight, BMI and position of the sleeper. Coils are superior than a solid Dunlop latex mattress in reducing pressure points.

When we originally talked, you told us “I generally prefer plush to medium. I find firm causes pain and too much pressure for me.” For this reason, we suggested the Cumulus because it’s the only mattress we have that matches that criteria. All Dunlop latex mattresses will have some pushback to them because they are made of dense, pure rubber and that can causes pressure points to some sensitive sleepers.

The good news if you find the mattress too plush, is that you can firm up the mattress by simply exchanging a latex layer for a firm one. I suggest you get a firm Dunlop latex from us and experiment with the soft, medium and firm layers to find what works best for you and then you can return the layer you don’t need. By placing the firm layer over the core, that will keep you more on top of the mattress and then you can decide if you prefer to sleep on the medium or soft latex layer for your top layer.

Here are the instructions if you want to proceed with a layer exchange.

I hope this helps and don’t forget what Maverick said earlier in this thread that it can takes weeks or months to get use to a new mattress, so don’t give up…

All the best!

Hi, Onyx: After a decade on memory foam and three VERY expensive ready-made mattresses, I too went to latex. I did a DIY build (components from LMF), however, so no experience with hybrid that includes coils. As for the latex itself, it is very different from memory foam. Think of memory foam as an angel food cake and latex as a pound cake. Less squish, more support and far more bounce. When layered correctly for your build and sleeping position, it “fills in the gaps”, eg. lower back. Your questions refer to latex in general, but the density makes all of the difference in the world and a mattress is typically layers of different types (Dunlop and Talalay) and densities. You do not mention either. I am about your weight and have firm Dunlop, then medium Dunlop, then soft Dunlop enclosed as a mattress. On top of that I have medium Talalay as a separate topper. I have back, hip and neck pain but with the aforementioned layers on an adjustable base I’m getting the best sleep I’ve had in many, many years. The neck pain, however, is almost totally dependent on the pillow you use. Your neck should be aligned with your spine, NOT with your head bent up like most pillows do. I have found microbeads and now millet hull pillows to cradle my neck and keep the arthritis fairly happy. Good luck in finding your perfect sleep solution.

Writing this at 3am because I can’t sleep on this matters.

Update: mattress came with coils, a medium Dunlop layer, and a soft Dunlop layer.

Mario from MFC suggested a few things to try and so far the best solution is just having the medium layer on top of the coils. However my hips are still sinking, and I still can’t get comfortable.

Mario suggested I exchange(I would be responsible for shipping which will be hundreds of dollars as I’m in Ontario and MFC is in BC) the soft layer for firm. And if that doesn’t help, purchasing a firm latex core. However he thinks that will be too firm. So am I screwed? I’m about $2300 in right now. Do I keep paying more for trial and error? When I provided more details and asked for more advice on narrowing down which option to choose, so as not to keep funneling money into costly mistakes, Mario told me to post here.

I sent MFC the photos attached to show how much my hips dip in this mattress. I asked Mario if my spine should be more neutral (this is what my occupational therapist is telling me), but he would only say that “there is nothing wrong with the mattress. I’ve never had a coil mattress that compresses this much.

I’m frustrated, I’m tired (a lot of tossing and turning), and I’m worried I’ve wasted my money.

Onyx,

For your back sleeping, your hips are sinking way too far down. Looks uncomfortable.

I am traveling at the moment. Looking at the pictures you provided, there are certainly a few things that need to be discussed. One quick example is one pic that shows you at the edge of the mattress. This is fine, if that is where and the position you always sleep in, if not, ot is not the appropriate picture and postion to present when taking the pick. The same goes for your side sleeping position, that picture should be taken showing the back of your body, not the front.

Any components you have is not a waste of money. Perhaps one layer may need to be altered or replaced, or used later as a topper in conjunction with swapping it in the body of the mattress with something firmer.

You definitely dont want to sleep in any pain, but you also dont want to plant the seed that its not going to be uncomfortable before it even happens.

We can dive deeper into it tonight.

I’m trying to be optimistic. I’m looking for a solution. It’s just defeating when the “expert” who sold me the mattress is being condescending and dismissive. This will be the last time I purchase something this big without an option to return. I look forward to reading your advice, and appreciate you wanting to help.

Hi Onyx,

First off, let’s be real, no one wants to be in pain. There’s a big difference between pain and discomfort, though. We all know what pain feels like, but discomfort can be a little trickier. It might just be our body reacting to something unfamiliar. Even with an open mind, we sometimes shut down physically because we’re not ready for what’s happening, and that can lead us to talk ourselves out of something before giving it a fair shot.

You even mentioned yourself that the latex didn’t feel like it was pushing back, and that your old memory foam felt firmer, even though you admitted it was sagging. That’s a really important observation. Memory foam compresses and sinks without pushing back at all, which can feel firmer in a way because it just gives and stays there. Latex, on the other hand, pushes back more in areas where there’s pressure. It’s a different type of support and can feel unfamiliar at first, especially if your body is used to a slower-responding surface like memory foam.

A very similar thing happens when folks sit on the edge of a mattress that uses edge to edge pocketed springs. They think they can sit on the edge and it will remain stiff like a chair. This is a big misconception regarding edge support. When the full weight of the body sits on a small area of coils that were meant to be used with all of its other twin brother coils to support an entire body, you get sinking in that small area trying to support an entire body’s weight, whereas someone lying on the same mattress, along the same edge, will have excellent support and just the right amount of contouring to keep one comfortable. So, it is not how the mattress reacts to you crawling on hands and knees, it is how your entire body rests on the surface.

That said, I personally don’t think anyone should have to endure with either pain or discomfort for too long when adjusting to something new. How long is too long? Well, if someone is really paying close attention, there should be slight improvements every day, and ultimately it will all come together.

It can be tough to tell the difference between the two (pain and discomfort), and that alone can be frustrating. Just because what you’re feeling with your mattress might not be textbook “pain” doesn’t mean it’s not real. Mattress feel is super subjective. Two people the same size and weight, say, identical twins, could try the same mattress, and one might say it’s firm while the other thinks it’s soft. Neither is wrong. It’s just how it feels to each of them. Conversely, there are those who believe they need a plush mattress due to some physical or health issues, and in reality, too much contouring causes more pain, where a flatter, firmer surface alleviates the pain and/or discomfort.

Still, mattress makers label their products in a way that gives people an idea of what most (about 80%) are likely to experience. But that still leaves plenty of room for individual differences.

Now, looking at your photos, here’s my take: In one of them, you’re lying almost right on the edge of the mattress. I can see some sinking at your waist, hips, and butt, which makes sense. But I’d be curious to see the same shot with you more centered on the mattress. Just for reference, I also sleep right at the edge of my mattress. When I test mattresses, I do both, lie on the extreme edge, something most do not do, and in the main sleep area of the mattress, they way the 80% do. Why? It is because I know that’s where most people sleep. When testing a mattress, it is not about me, it is about what I imagine the majority of folks will think.

In the other photo, it’s interesting. You’re not sinking much at all in the same areas. Actually that photo looks quite good. There does seem to be a slight incline from your chest up to your shoulders, but it is hard to get a real sense, since your neck and head is out of the picture. The line drawn to show your alignment, this isn’t quite accurate, though, in either picture. In one picutre, the side angle, it almost looks like your pillow might be too tall, or maybe you’ve got very broad shoulders. Either way, based on that image, the mattress looks like it’s giving you the support on would expect. For a better read on your spinal alignment, we’d really need a photo taken from a wider angle, with your whole back visible from head to knees. In the edge of the mattress picture, if the segments of the mattress are around 2" at each seam, even at the edge of the mattress, that only accounts for less an an inch which is not a lot excessive contouring going on.

While I was on the flight home, I was thinking about all this. Initially, I was leaning toward recommending a firmer comfort layer and then using a topper to fine-tune the feel in certain areas. But in your side-sleeping photo, honestly, the alignment looks pretty darn good, which gave me pause. But as I read your posts, it is taking me back to a medium top layer with a firm layer between the top and springs. I was reading what BLK56 chimed in, and your set up is not much different except for the support layer being springs rather than a firm latex. For your weight, I have to agree that the spring layer will better serve you.

I found this photo online from a company I’ve been considering inviting to TMU. You can see how much contouring is going on there. Is a Hybrid Latex Mattress Good for Back Sleepers?

Other than her not using a pillow to keep her head and neck in the correct position, there are similarities on her contouring the mattress to yours.

Now take a look at these two comparison images. These usually surprise people the most: The first group.

In the bottom two pictures, the main issue is either a pillow that’s too thick or the mattress being too firm and not contouring enough. This is exactly what had me second-guessing myself on that flight. Your photo looked similar to the good alignment in these shots, but only from certain angles.

Here’s another illustration that often brings up questions:

At first glance, people usually think that angled spine position looks wrong. But funny enough, this is exactly how I sleep. For someone in that position, it’s actually perfect alignment.

Look, I am not privy to your conversations with Mario or whomever you have discussed your situation with at MFC. If you indicated you liked a plushier feel, than the medium and soft over coils would be the way to go. If you werent quite understanding what plush is relative to your memory foam mattress feel.
The good thing is, if you remove the plush and place a firm above the coils, you can always use the soft latex as a topper.

Also, I dont remember, but do you have an chronic pain issues generally?

The first step, I think is to remove the soft dunlop layer and see how the medium over coils feel. You are not compressing the medium enough for it to be an issue of “feeling” the coils. For reference, my mattress is firm coils with 2" of HD foam on top of the coils, on the side of the mattress we sleep on. So 2" of medium latex over coils, is not unheard of. If that feels better to you, get another medium layer, if it seems too soft, then get the firm, and as I mentioned, keep the soft as a topper option.

For now, and I mean no disrespect, I would keep the conversations between you and MFC, (who ever you have talked to) leaving the rhetoric aside, or as we used to say, hang the ego’s at the door, and just solve the problem. Everyone is likely to be charged up and frustrated, and you don’t want that to interfere with the success of your comfort. Solve the problem first and then decide if you are going to mail them holiday cards later.

All the best,

Maverick

Hi Onyx,

Chiming in briefly to help gather a few key pieces of information so we can better support you and find some clarity about what’s going on with your setup. From your photos, it looks like you have a queen or king-size mattress, so let’s do a quick check of the foundation first:

  1. Could you partially (or totally) remove the mattress and take a clear photo of the foundation? For queen and king sizes, a center support reaching to the floor is crucial. If it’s missing or inadequate, it can cause sagging and affect how the mattress performs. This is often misattributed to the mattress itself. If you notice any sagging, you’ll need to place the mattresses on the floor so that we can further. Also, let us know what the distance between slats is and how thick the slats are.

  2. In your side-sleeping photo, we’re not seeing your head/neck alignment with your pillow. A high-loft pillow can impact spinal curvature significantly, so a full head-to-toe photo from the back, in your natural sleeping posture with your usual pillow, would be very helpful.

  3. The same goes for your back-sleeping position. Seeing how your body aligns and the pillow setup will give us important clues. You can cover your face with a scarf for privacy, but make sure that the scarf covers only your face and not your neck.

  4. Can you describe the location of the discomfort and whether it appears at the beginning of the night or later on? Does the discomfort ease up in the morning? And do you feel the same discomfort regardless of sleep position?

Let’s Try a Simple Experiment

To help identify whether the comfort layer(s) are playing a role in the issue, try this:

  • Remove the soft layer and sleep with the medium layer directly over the coils. Let us know how this feels.
    This test helps identify whether the mattress might be too thick or too soft for your body type. It seems you’re a lighter-weight sleeper, which generally calls for a thinner and softer comfort layer. Here’s an article that might shed more light:
    :point_right: Sleeping Style, Preferences, and Statistics

Remember, softness and thickness go hand-in-hand. The thicker the mattress, with the same layer configuration, the softer it will feel. For lighter bodies, thicker, softer mattresses can lead to improper support. Your mattress is 11" and someone with your body type usually needs no more than 9". Thicker mattresses work well, but the softness may need to be adjusted.

Note: The 7" Leggett & Platt Innersprings coil unit in your mattress is highly supportive and well-matched for lower-to-average BMIs. It’s unlikely the issue lies in the support core unless there’s a rare defect, in which case a visual inspection (and photo) can help Mario assess further.

Optional 2nd Experiment

If you experience pressure points after removing the soft layer, try swapping the medium layer with the soft one. This will adjust the surface feel, offering more pressure relief while still maintaining adequate support. Let us know how it feels.

Also, let us know roughly what percentage of the night you spend on your side versus your back—this can offer valuable clues in dialing in the right comfort configuration.

It also looks like once you land on the right setup to reduce discomfort, your body may need some time to adapt to the new, more supportive sleeping surface. If your previous mattress had sagging or poor alignment, your muscles have likely been overcompensating for a while, keeping the back and hips in alignment. A transition period is totally normal as your body learns to relax into proper posture again.

A bit of trial and fine-tuning is part of the process, whether you stick with this mattress or explore a new direction. But with the thoughtful guidance from Maverick and Mario, you’re in excellent hands.

And just so you know, @Mario isn’t just “in the business.” With decades of hands-on experience designing mattresses and a deep understanding of materials and biomechanics, he’s helped thousands of people (from side sleepers to chronic pain sufferers) find sleep solutions tailored to their unique needs. His “Trusted Member” and “Expert” status here at TMU isn’t just a isn’t a marketing badge; he and his company have earned it through proven results, transparency, and long-standing customer trust.

Hang in there—we’re in this with you!
You’ve got one of the best in your corner.
