The Best Foundations or Base for a Latex or All Foam Mattress

Hi Beth2014,

The foundations from SleepEZ and USBoxspring are the same foundation.

The USBoxspring foundation and the mattresses.net foundation both use the same wood (Spruce) and are fairly similar. The main difference would be in the cover with USBoxspring using an organic cotton cover with a quilted border.

You can see my thoughts about a wire grid type of foundation for an all latex mattress in post #10 here. While I would tend to use a foundation with more surface area for an all latex mattress … if you do decide to go in this direction and it does squeak (and most of them have some feedback about squeaking) then it shouldn’t be hard to fix the squeak either by tightening any bolts or with a washer or by lubricating any metal on metal contact points that are squeaking (usually in the folding braces). If you purchase one that doesn’t have a headboard attachment then they are quite inexpensive to purchase.

Thanks. I thought when I called them they told me the foundation was made of pine. Do you know if there’s any difference in terms of quality, strength, etc. between spruce and pine?

Hi Beth2014,

You can see the properties of different types of wood here (just scroll down). As you can see Spruce has a higher bending strength and stiffness than all three types of pine but the stiffness of a foundation will also depend on its construction not just on the type of wood.

When I talked with one of the owners of USBoxspring they told me it was made of Spruce (see post #295 here).

My EZ Sleep foundation arrived today via FedEx. We started putting it together following the directions and had a problem:the 2 center slats (CA King size uses 2), would NOT fit into the provided slots of the head & foot board pieces. It was like 1/2 " too long. The company (Habitat Furnishings) is closed for the weekend. …sent an email. Our latex mattress will arrive next week and we wanted to at least get the foundation together. Ha Ha they say it takes only 20 minutes to put together. Has anyone else ordered this foundation for their (latex) mattress? Their web site has an easy video tutorial, but maybe we got center slats for a regular king instead of a CA king? It was going well up to that point. …help!

Hi PC gal,

I’m not sure what may be happening but it may be worthwhile trying to call the manufacturer here to see if they are open on the weekends and can help solve the issue you are having.

Did you fit the center support rails into the slots on one end before you attached the sides and the other end?

I don’t have any personal experience with this foundation but perhaps another member that does may have encountered the same issue and be able to help.

A cal king is 4" longer than a king size so it’s not likely that that is the issue if your center support rails are only 1/2" too long.

Other than this you may need to wait until either Habitat or KD Bedding are open again.

Thank you for your quick reply. I just sent an email directly to the manufacturer and will call them tomorrow . I tried your suggestion after trying the basic assembly the directions specified didn’t work. We got the center slats in but then couldn’t get the foot board to connect to the two side rails! The directions were easy, but it didn’t work out for us. We stopped because we didn’t want to force any parts together and break anything.

Hi,

I am buying a second Latex mattress from Spindle (GREAT company and products) and am thinking about the EZ Sleep foundation too.

FWIW, I talked to them and found out a few things that may be of interest AND have a question or two.

First, some of you may have noticed a similarity between KD Bedding’s EZ-Sleep foundation and Carolina Mattress Guild’s E-Z Sleep foundation. The names are identical except for the dash between the E and the Z. It turns out they are the exact same foundation, at least according to KD Bedding.

KD Bedding also stated that the gaps between the slats is close to 5". The slats come in a slat packs (2 per foundation) that unroll to evenly space the slats. They say you can buy an extra slat pack for $20 retail to bring the gap down to around 2.5". Since you are only adding 50% more slats to get half size gaps, I guess that is enough information to calculate the width of the slats but I haven’t done the math.

They also said they are about to release an updated design so if anyone plans to order in the future, recheck everything before you do.

Questions:

Any unintended consequences of scrunching up the cloth in the slat packs to move the slats closer together and leave room for the extra pack (other than the hassle)?

If it turns out the gaps are still over 2.5" does the fact that this latex mattress will have a firm bottom layer, give some slack compared to a softer latex? I understood the reason for small gaps was that Latex would try to sag into larger gaps so it would seem that the stiffer the latex the bigger the gaps could be before it’s a problem…

Hi HoosierDaddy,

None that I can think of as long as the slats were secured to the frame so they were less likely to shift (I would screw them in).

Almost all latex mattresses have a firmer bottom layer so the suggestion of gaps that are 3" or less would be based on this. If the bottom layer was softer then it would probably be a good idea to use smaller gaps than you otherwise would (rather than thinking about using wider gaps for firmer layers). This is one of those “range of risk” questions where there are no black and white or specific answers and a more solid and evenly supportive support surface with less flex is generally “better” than a more flexible or less evenly supportive support surface with more flex (unless the flex of a support surface is intentional and part of the design of the sleeping system) but you are right that firmer layers on the bottom would be less likely to sink through any gaps in the support surface over time than softer layers.

I’m considering a new mattress for my son’s bunk bed. He is 11 and I’d prefer to get a latex hybrid from brooklyn bedding. The complications arise with the logistics. His current mattress is about 12-13 inches high and sits on an (antique, like the bed) frame with wires that sits within a metal “rim” in the frame of the bunk. I feel the wire frame is not a good support system and would like to replace it with slats.

First, would twin size slats sit nicely inside the metal rim of the bed and provide adequate support? Or would we be better off with a low profile foundation? I lean toward the slat option so as to not raise the bed too high. Once I buy a 5 inch foundation, then I’d like a pretty low profile mattress which limits my options.

If slats are a decent and safe/supportive option for my situation, do you have an opinion on these slats? From the description, they sound like they may be of higher quality than most and provide two different slat gap option sizes: Organic mattress foundations of wood, cotton, wool. Organic & Healthy, Inc
Is this a reputable company, in your opinion?

Thanks for any help you can provide!

What is in the latex hybrid mattress? Is it a combo of the 2 types of latex? Is it 100% natural (vrs. Synthetic)? This is just as important as the foundation/slat question. I put my slats in a foundation specifically made for a latex mattress. that foundation sits on top of the metal bed frame nicely. I definitely wouldn’t use wire under a latex mattress. But ,I don’t know if a latex mattress (even a twin size) could be supported by just the slats sitting on top of the metal bed frame . The latex is heavier than a regular mattress. With a bunk bed , I guess the bottom bed could support a latex mattress if you also used a foundation with wood slats. I got mine on line through Habitat furnishings. The foundation is EZ sleep. As for the top bunk, I would ask the latex mattress place that you are buying from.

Hi Mightyh,

I would always measure to make sure that any support system fits inside your bedframe (they provide the exact dimensions on the site) and you will also need to make sure that there is a way to secure the slats to the frame so that they don’t shift or fall through the frame. If you confirm they will fit and they can be attached securely then douglas fir is a strong wood and you would be fine with either one of the gap sizes as long as the bedframe itself is strong enough to support the weight of the mattress and anyone that sleeps on it.

I haven’t talked with them and don’t know them personally but they certainly appear to be reputable to me.

@PC gal,

Brooklyn Bedding is a completely transparent manufacturer and lists the materials in their mattresses on their website (and will answer any specific questions that their customers have as well) so that all their customers can know exactly what is inside any mattress that they purchase from them.

As you can see here … the slats in your foundation may be a little too far apart to be the best choice for an all latex mattress without an extra set of slats.

Phoenix

Thanks for your response, Phoenix. My son is currently sleeping on the innerspring-over-wire-frame-within-metal-rim set up, so I guess I can assume the metal frame will hold an alternate system? I don’t know how I would otherwise determine the strength of the frame….

I can’t see any way to secure the slats/foundation to the metal rim. The current wire frame just sits inside it.

I did chat with Mario at Brooklyn Bedding and he recommended the Bamboo Bliss, but said the wire frame was not a good foundation option - hence the beginning of my questions! I’m not sure I feel like I’ve figured the answers out, but I appreciate what help you were able to offer.

Hi Mightyh,

Gluing velcro to the frame and to the slats would help prevent them from shifting.

If your frame is a standard size that is the same as a typical steel bedframe (something like these) with a lip on the outside then a standard size foundation in a low profile or a bunkie board or something like this that is the right size to fit snugly inside the metal lip should work well. There is more about foundations and other support systems in the foundation post here.

A foam mattress (such as latex or a latex/polyfoam hybrid) will generally do best with a rigid, non flexing, and evenly supportive support system underneath it. As far as the strength of the bunkbed frame itself and it’s ability to hold the mattress, your support system, and your son, unless you know the weight that it is rated for you would need to use “best judgement” based on the quality and the strength of its construction.

I have my mattress on a ikea base but the slats are too far apart I think its 7" apart… What should I use to fix this? I’m guessing bunky board? Or particle board/MDF?

Hi WadeB,

You can see my thoughts about a solid platform and the restricted airflow under the mattress in post #10 here. If there are no other alternatives though and the other risk factors are low then it would probably be worthwhile adding a sheet of plywood or MDF.

A slat conversion like this would be better yet if it was stable on your base.

Which Ikea base do you have?

Phoenix

That’s the one I have… It looks great with the wood legs but man the gaps are large I’m thinking this may work? Shop Quality & Affordable Products - IKEA CA think that should fit the base seeing how its both from Ikea

Also there’s no link to post 10 for your thoughts on solid platform

Hi WadeB,

Oops … it’s fixed now … sorry :slight_smile:

I agree that your foundation isn’t one that I would normally consider. If the Laxeby was stable on top of the foundation and didn’t shift or slide with movement (it normally fits into a bedframe with a lip that would stop it from sliding) then it would work yes.

I purchased a Cal King 9" 3 layer Latex Mattress (Firm / Medium / Soft). This has probably already been mentioned but I could not find a foundation in this thread like this one. Do you think this would work well with the Cal King Latex?

European Posture Support Platform Bed Frame

I’m assuming the King and Cal King would be like the one pictured of the Triple wide. But if this foundation for the Cal King is the triple section foundation, I could see us sleeping more in between the slate slopes and more where the 3 sections join. How would that effect the performance and feel of this foundation thru the mattress?

Hi MrM1,

I’m not familiar with the European platform bedframe you linked but I would be somewhat cautious based on what I can see.

It’s a fairly new product made by Boyd Sleep Systems and you can see in the Walmart description here it will support 300 lbs per side of “dynamic weight” which tells me that it may not be as strong as I would be comfortable with and this and the price would probably be a more accurate reflection of its quality and it’s “real world” strength and durability than the static weight rating. Some of this is indicated in the more negative reviews on Walmart.

It may also affect the feel of your mattress (for better or worse) and it’s also possible that you would feel the sections where the slats are attached where there is no flex under the mattress. How much you would feel this would depend on your weight and sensitivity and on the specifics of the mattress (you would be more likely to feel the firmer sections with higher weights, a thinner mattress, or softer layers).

If you do decide to purchase it I would buy it from Walmart partly because of the lower cost but mainly because of their great return policy so you can return it if there are any issues with durability (such as legs bending or slat supports breaking) or with how it affects the feel or performance of your mattress.
