Anyone have any experience with this as a core to a latex hybrid mattress? I’m looking at building something from Arizona Premium Mattress Co with that core/support system.
Hi davo32683,
The Quantum Edge is a durable and supportive innerspring unit, and has been used by thousands of people just at Arizona Premium Mattress in their Ultimate Hybrid Collection, as well as many other bands domestically. There’s a bit more information about this spring unit in case you haven’t already seen it here.
There may be members here who have used this particular spring unit as part of their DIY mattress and maybe they’d be willing to share their results. Of course, any combination of materials they use in a completed mattress will change the overall feel of the spring unit, but their advice on working with the product and its durability might be useful for you in making a decision.

Thanks. That’s kind of what I was looking for. Maybe just some feedback on that product itself. Not that it will be a perfect fit for us.
Avocado Green Mattress uses the Combi-Zone as well, according to them, but I see the Bolsa used on several others (Luma and Plushbeds). What might the difference be between the Bolsa and the Combi-Zone?
Hi davo32683,
Here’s some information on the Bolsa and the Combi-Zone. The Bolsa is more or less the “standard” pocketed spring from Leggett and Platt. It can be manufactured in many different varieties per a manufacturer’s request (gauge, turns, profile, diameter…). The Combi-Zone is a combination of different styles of pocketed springs in different zones. These could be different Bolsa springs, or perhaps a combination of Bolsa and Quantum springs. These are commonly zoned in three or five zones, depending upon the request of a manufacturer. Some designs can allow for the shoulders and hips to sink in a bit more, or others can provide support in the middle third of the mattress. Again, Leggett allows for quite a bit of customization, and a manufacturer can work with Leggett’s designers.

I have a question regarding what kind(s) of mattress cover would be suitable for the Leggett and Platt Combi-Zone (from Arizona Premium) and a 3 inch latex comfort layer.
The Queen Bamboo-Wool is what they recommend in some videos on their site, but it’s quite expensive and I’m not sure I’d like wool in the quilting (I’d like to sleep as close to the latex as possible).
My question is would a stretch-cotton cover be suitable for the Combi-Zone with latex on top? I ask b/c the coils don’t have a foam encasement, and a stretch-cotton cover is thin.
Hi mitchellcole,
If you’re looking to experience the maximum point elasticity of the latex upper layer, you are correct that some version of a stretch-knit or flexible cover would more easily facilitate that.
The Quantum Edge spring unit doesn’t necessarily need a thicker encasement, and with a “stretchier” covering you’ll simply feel more of the outline of the springs along the side of the mattress.
If you decide upon the LMF covering, I would phone them and ask how snugly they fit, and if they would recommend their 10" or their 11" covering with the combination you’re considering (8" spring with 3" latex).

That makes sense. Thank you!
Hi mitchellcole,
You’re very welcome!

Hi Phoenix,
I’m posting my question here because I can’t seem to find the “New Topic” button (and I spent the last half an hour looking for one, incl. things like [url=https://forum.mattressunderground.com/t/how-do-i-start-a-new-topic]https://forum.mattressunderground.com/t/how-do-i-start-a-new-topic[/url]).
Anyway, my question is related to your quote above. I just bought a well-regarded latex-innerspring hybrid mattress, which we actually quite like. It comes with Quantum Edge Bolsa springs, and therefore has no foam encasement. I don’t know if this is normal or not, but I’ve never seen a mattress that had absolutely no outer layer separating the springs from the “outer world”. Sure, the mattress comes with the Tencel mattress cover so you’re not touching the springs directly, but apart from this super thin layer of fabric there’s nothing else at the side so you can very much feel the outline of the springs when you touch the side of the mattress. It feels both cheap (for the mattress that costs around $1000) and at the same time I’m wondering how durable/safe this is (I can easily imagine the side of the mattress being ripped when moving, which would normally be a cosmetic issue only, but here you’re going to get straight to the springs).
We had the Eco Terra hybrid mattress before but returned it because it was way too soft. That mattress has the same Quantum Edge springs and yet it had some sort of thicker material between the cover and the springs, so you were never directly touching them.
Honestly, I’ve never even thought about this separating layer until we got this mattress where I immediately realized that something is amiss… Is this normal? As I said above, we like the mattress, but I’m not sure I’m quite happy to spend $1000 on a mattress where I can easily feel the individual springs at the edge of the mattress.
Thanks!
Hey Hrastnik,
I’m not Phoenix, but perhaps I can help shed some light on your question/concern.
Mattresses using perimeter polyurethane foam/extruded polyethylene/injection molded foam encasement are “newer” relatively speaking within the industry (past 2+ decades) in one form or another. The polyurethane foam encasement tubs really became even more popular with the advent of one-sided mattresses. Most recently, pocketed spring units using thicker/smaller edge springs for extra edge reinforcement have become popular as methods to provide more flexibility for innerspring mattresses (helping to work with adjustable bed bases), helping boxed bed companies create products that can be compressed/shipped, create a more seamless transition from the main part of the mattress to the edge, and to help combat pricing issues of polyurethane foam versus steel.
But having “springs to the edge” is common, and there would be more products overall in the marketplace that have this than ones that don’t. There are still many products using LFK, continuous coil and Bonnell springs to the edge of the mattress, and these spring have no fabric covering their innerspring unit, and there are no issues with durability and the springs don’t poke through the side of the mattress. While yo can of course “feel” the springs along the side, there’s still a barrier of the border panel and whatever material (wool, FR fiber) is quilted to the back of it between the spring and the outside of the mattress.
With these new pocketed spring mattresses using this newer edge configuration, the springs themselves are usually wrapped in a strong non-woven material which holds them in these pockets, and then there is the aforementioned border panel around the perimeter of the mattress.
I can’t speak to your particular mattress, but the Quantum Edge products (there are different variations) tend to be good quality pocketed spring units and are already quite ubiquitous in the industry. I personally would have no concern with using them (I do carry a few items using these spring units) as well as versions from other innerspring companies, and in 25 years I’ve personally never had a such a spring work its way out sideways along the border.
I’ve had people comment previously in my showroom that they can feel the springs along the side of such mattresses, and my normal reply is that you don’t sleep upon the side of your mattress, and as long as the materials are high quality and the method of assembly is good, you should be just fine, and it’s more appropriate to focus upon the comfort layers used within the mattress. But everyone places their own personal levels of importance upon certain features of products, and if you want a polyurethane foam tub around the perimeter of your mattress, there’s certainly nothing wrong with that 
. You’d just want to make sure that whatever you’re considering uses good quality materials, and realize that there may be shortcomings with the flexibility of such a product should you choose to use it with a power foundation.
I hope that helps to address any concerns you may have about these “newer” edge reinforcement system, which in reality aren’t new at all but are just different ways of configuring different types of pocketed springs within the same innerspring unit.

Hi Jeff,
Thanks for the fantastic and very informative reply! I really appreciate your taking the time!
Now, I know QE springs are typically found in high-quality mattresses, so I have no doubt there’s nothing wrong with them. My problem is precisely with the “border panel” you’ve mentioned - there is none! There’s the cover and then the springs, and there’s nothing else between them… This is why I’ve been so surprised when we received the mattress, because we’ve tested another one with QE springs before and it was, well, a regular mattress with the “border panel” and everything else I’d expect in a mattress - it was just too soft.
I’ve reached out to the manufacturer to see whether that’s normal or if they somehow forgot about the “border panel”… Let’s see what they’ll have to say about it. I’ll post an update once I hear back from them.
Thanks,
Maya
Hrastnik,
A zippered mattress encasement generally would not be constructed with a border panel, as that is part of a production process when a quilt panel is attached to a border panel with a tape edge. There would still be fabric surrounding the product separating it from the “outside world”. There would also generally be a layer of FR fiber or wool attached to the innerspring unit or quilted to the encasement to pass federal flammability regulations. Feel free to post a photo should you have other questions, but what you’re describing doesn’t sound unusual.

A somewhat different question regarding coils (like the Combi Zone)–
Based on what I’ve read here and elsewhere, it appears that the Combi Zone is recommended for heavier people with higher BMIs, because of the lower gauge and the zoned support.
Is there much, if any benefit for people who weigh less? I am ~150lbs with a BMI around 22-24. Will there be enough benefit for the additional cost for the Combi Zone coils (+$100 or more)?
The regular Bolsa coils I’m told are 15g, whereas the Combi I’m told is 14g-13g-14g (and of course higher gauge perimeter coils). So it seems Bolsa would also feel a bit less firm overall, even without considering the zoned support.
Right now thinking about the regular Luma Mattress (which only has 1.5" of Talalay latex on top), would that even provide enough of a comfort layer on top of coils? (Or the Arizona Eco-Sleep).
Thanks for any input!
The innerspring units you mentioned are made in different versions (gauges, profiles, pre-compression and so on) for different manufacturers, so there is no standard answer. It is common for some manufacturers to offer a “more basic” unit and also have one that offers more springs or more support (sometimes this can be a version of the Combi-Zone), so it’s all comparative and relative.
You always want to have good support within your mattress, but some petite individuals do prefer an innerspring unit that is not as firm. Of course all of the layers of a mattress work together to provide your overall comfort, and the layers closest to the top of the mattress will provide the most dramatic difference in perceived comfort, but depending upon the layerings above a chance to an innerspring unit can also be noticed, especially with pocketed spring units. Larger individuals tend to notice this more, or people testing out mattresses that have fewer comfort layers atop the innerspring unit.
The easiest way to tell the difference would be with two mattresses side by side that are using the exact same comfort material but different innerspring units, but that isn’t so commonly found. Aside from that, my best guidance is to trust the suggestion of a knowledgeable manufacturer or experienced comfort consultant. They should have good experience with different somatotypes and masses and how people in those particular categories tend to respond to their products. I always tend to defer to strong deep support / alignment, as it is the foundation of getting into the deeper phases of sleep.
Hi Jeff,
Appreciate your knowledge as always (I’ve read many of your posts here).
I guess it gets confusing also because I got different answers from two manufacturers, one thinking that I would not really notice any difference or benefit with a combi vs regular bolsa, and the other saying they thought I would have less back pain/aches with a combi.
The two I am talking about is Arizona Premium Mattresses and Luma, btw.
There are differences in the materials being used, their combinations and the actual spring units in question, and these manufacturers are speaking to their own experiences with consumers using their own products, so I would certainly give quite a bit of credence to the advice they offer for their own brands. They will be the best source for reliable information about their own products (unless you happen to work in the IDEA lab at Leggett and Platt in Carthage, MO. 
).
