Hi justwannafindmymattress,

Certi-PUR-US polyurethane foam states that
There would not be fiberglass in the certified foam used for mattresses, pillows, or upholstered furniture. However, some mattress manufacturers surround a mattress’s foam core with barrier fabrics made from fiberglass to help meet government standards for mattress flammability. A mattress zipper is usually there for easy assembly at the factory and not for the customer to use. For that reason, never remove the cover of your mattress, even if it has a zipper, unless the mattress cover is specifically intended to be removed for laundering. Consult the manufacturer’s website or call their customer service department before you zip off your mattress cover. The best way to protect your mattress from getting soiled is to use a mattress pad or mattress protector on top of the mattress. These products will not diminish the feel or comfort of your mattress but will help keep it clean. Many of these products have waterproof features, and some protectors that cover all sides of your product have the added benefit of deterring bedbugs.

Here's more information about fiberglass in the mattress covers
Reading this blog could save you a ton of time and aggravation. In just the past year or two, consumers have been asking us a question that has also received increased media attention. It has to do with fiberglass. To be absolutely clear, foam manufacturers do not use fiberglass to make the types of foam we certify through the CertiPUR-US® program.

But sometimes there may be fiberglass in your mattress cover or in a fabric “sock” that is pulled over the foam core before the cover is put on — in what is referred to as a barrier fabric. These barrier fabrics are designed to meet government flammability standards. This is a perfectly legitimate practice. But it is important the fiberglass stays safely contained inside the mattress.

For that reason, do not remove the cover of a mattress without first reading product care instructions carefully, consulting the manufacturer’s website or calling their customer service department. Do not take any chances.

Of course, some mattresses are designed with a cover that can be removed without creating a problem, but just because you see a zipper, do not assume the cover is removable.

Sometimes the zipper is there only for easy assembly at the factory and not for the consumer to use. In these cases, unzipping the cover could be like opening Pandora’s Box. You could release glass fibers into the air or onto you, which is not going to be fun (or even possible) to clean up or put back.

That’s why it’s a good idea to purchase a separate mattress pad or protector to keep on top of your mattress to protect the surface from spills and stains. Many mattress protectors have waterproof features, and some protectors that cover all sides of your product have the added benefit of deterring bedbugs (a topic for another day!). These bedding accessories can be easily removed for washing.

OK, enough said. I will zip it right here!

I hope this helps you find the mattress that's right for you and your family.

All the best!

I figured I'd throw an update on this since I haven't posted much in a bit but overall this DIY mattress has been the most comfortable I've ever slept on!!! It has actually gotten better with time instead of worse as store bought mattresses often did as they broke in. I now have zero shoulder, hip or back pain anymore and I haven't had to make any more adjustments to either the latex layers or the airbed setitngs since my last post. I've been using the Purple mattress cover on the latex layers and it works great while the flobeds bottom portion of the cover is used only on the airbed part. It took me a little bit to figure out how to make the bed so the airbed base didn't show from under the duvet, but I finally figured out the technique and now all is good. This story is quite the saga when you read it from the beginning but hopefully I can save others some headache and money from some of the mistakes and lessons I learned along the way.

Hello! Long-time reader, first time poster here on the forum. Thanks so much for all of the great info you share!

I'm currently sleeping on a fairly comfy DIY mattress. But, after several months of sleeping on it, I've become concerned that I'm not getting sufficient spinal support.

I'm a combo sleeper (side, stomach, and back). I'm 5'3" and weigh about 135-140lbs. And, I'm curvy; so contouring support is a big deal for me.

But, I'm waking up to SI joint pain. This is by far the "cushiest" mattress I've ever slept on. So, I suspect I'm sinking into the mattress too much, putting strain on my lower back.

My current stack is:
1" 4.5lb memory foam
2" soft talalay latex (19 ild)
3" medium dunlop latex (25-32 ild)
3" firm dunlop latex (33-39 ild)

After doing some research, I think I need a firmer support layer than the medium dunlop I currently have. But, I tried swapping the medium dunlop for a firm dunlop support layer and it was much too firm for me.

I'm wondering if an extra firm talalay layer (36 ild) would be a good "Goldilocks" compromise between the medium dunlop layer that's too soft and the firm dunlop layer that was too firm.

Option 1:
1" memory foam
2" soft talalay (19 ild)
3" extra firm talalay (36 ild)
3" firm dunlop (33-39 ild)

But, I know that talalay allows for more compression. So would swapping from dunlop to talalay in the middle layer leave me sinking into the mattress too far anyway?

Would it be better to keep the medium dunlop support layer and replace the soft talalay comfort layer with a medium talalay comfort layer?

Option 2"
1" memory foam
2" medium talalay (28 ild)
3" medium dunlop (25-32 ild)
3" firm dunlop (33-39 ild)

For providing more spinal support, without sacrificing the squish I need for side sleeping, which of these options makes more sense?

Thanks in advance!

I highligted the part above which is likely why your current design isn't working. Curvy people (myself included) need to have both good contouring and support. The problem is that often we need individual layers to do more than they are capable of and when they can't the end result is either misalignment or pressure points. You will get some additional travel by switching the dunlop to talalay but the issue is you may end up realizing it's still not enough and now you're out that money. The better way to combat this is through zoning (with talalay). I'd suggest trying a Flobeds v-zone layer in your stack, it's not cheap but when you have a hard to fit body type you need to be open to more elaborate solutions.

Suggested stack:
1" 4.5lb memory foam
2" soft talalay latex (19 ild)
3" Flobed V-zone layer (Soft)
3" medium dunlop latex (28 ild) - you may or may not need this layer, try both with and without it to see what's most comfortable for you
3" firm dunlop latex (36 ild)

Due to a torn rotator cuff, I need a soft support layer to reduce the amount my arm falls asleep. However, if that layer is too soft I get pain via my hips sinking through. Has anyone ever experienced creating a hybrid/split comfort layer?

I'm thinking I might benefit from having a 1/3 // 2/3 split - softer for my shoulders, firmer at the hips. I would be willing to buy two individual layers and cut them to size. But I am wondering if this is a terrible idea -- either because of having two materials instead of one (I would glue together if it makes a difference), or potentially really messing up my alignment. My other thought would be to simply add an extra bit of soft foam under the shoulder area, but would then increase the angle at which I'm sleeping.

Yes, this would work well and that's basically what many of the zoned mattress options are doing (Flobeds being one of the most configurable). Make sure to cut the layer just where your armpit would be to ensure you provide maximum support in the chest area and this allows you to take pressure off the shoulder which helps for your injury. You may need to experiment with what firmnesses you like best but overall it will work fine. You might also try the Flobeds convoluted topper on top as that adds extra contouring for shoulders/hips which could be beneficial in this case.

Due to the rather drastic differneces in BMI between you and your wife I think a DIY mattress with split layers would be a really good idea in this case. I would be hesitsant to destroy your current mattress as I went down that same path early on and ended up not using anything from my old mattress (it wasn't a Beautyrest Black, that may have slightly better components). Your BMI is going to need a fairly stiff base support layer to ensure you have proper alignment then additional comfort layers as needed. Something to think about anyway.

So, on the third day my husband started having mid back painand numb hands. I took off the cover and put everything on the foundation without the cover. I then had him get on the mattress and really looked at what was going on. The 3" layer of firm talalay seemed to stop the coils from engaging at all--they did not compress. I removed the 3" layer of talalay and added a 1" layer of dunlop as the transition layer. I then added a 3" medium (28 IDL) and a 3" soft (15 IDL), then zipped everything up in the bamboo/wool cover and added a Cozy Earth bamboo mattress pad (really thin more for coolng and protection). This has created the MOST amazing mattress we've ever slept on. It is soft and cushy, but very supportive. I think by using a thinner transition layer we are getting the full benefit of the Quantum Edge Elite coils. Our BMIs seem high, he is 5'10"/190 lbs and I am 5'4"/160, however we are both devoted gym people so we are a smaller size with lots of muscle mass, with broader shoulders. I think this was why the 3" soft over 3" firm was not giving us the countouring we need to keep from aggrevating our shoulder and hip pressure points. Thank you again for all your help. I wanted to give you additional feedback in case you have customers who are more muscular like we are.

Glad you figured it out. This is the hard part of doing a DIY mattress (ie understanding why it's not performing and knowing what to do to correct it). The key is as you found opening up the mattress and really looking at what's working and what isn't and then making those adjustments you need (in your case it was clearly a contouring problem since you both have more curvy body shapes).

Couple things to try.....

1) Not sure if Flobeds still ships to Canada but you could try them.

2) If you're near the border then use www.kinek.com and you can ship anything to a nearby border state and just go down and pick it up at your leisure. (what I use most)

3) Some customs brokers will allow you to ship to their warehouse on the border and they will complete the delivery in Canada for a fee. (I used this druing Covid when the border was closed, YMMV)

Hello all,

I just recently began the search for a new mattress. My wife and I are currently sleeping on a king sized innerspring we got for about $450 four years ago.

I've been exceedingly confused by the mattress industry, mattress review companies, and personal blogs online. One will say no, of course x mattress doesn't have fiberglass. We actually use a silica sock. Then another will say x company does contain fiberglass. I'm learning that silica sock typically means fiberglass. Or that's what a few online resources state anyway. It feels like it's all technicalities.

I've seen only a handful of horror stories surrounding fiberglass in mattresses becoming exposed, but it sounds so horrible that I'd like to avoid it altogether. But I still want to comfort of a memory foam like bed.

I usually sleep on my side, am about 180 pounds, and 6 foot 3. My wife has a different build and for that reason, I think we would do well with a split king bed. I started looking a few weeks ago and decided a split king with an adjustable base would be amazing. I'm tired of waking up with a sore shoulder and aches muscles.

As I mentioned before, I have been researching beds leaning on multiple mattress review websites. This led me to select the nectar premier, based solely on the fact that the claim is you get a quality mattress for about half the cost of the other guys. I was really narrowed down to purple, nectar, and ghostbed as brands to choose from.

I bought two twin xl nectar premier mattresses the other day for about $1800. For that kind of money, I'm thinking I could get something that doesn't contain fiberglass.

My issue is, the deeper I research into each mattress brand, the more I find people talking about fiberglass being in the construction somewhere. I found articles stating that nectar, purple, and ghostbed contain fiberglass. I know Ghostbed is a TMU member, so I thought maybe asking about it here would help me with my situation.

I'm thinking about canceling/returning my order from nectar, but if I do, I don't want to pay hundreds of dollars more to get a bed that STILL CONTAINS FIBERGLASS.

Unless, of course, throwing a mattress cover over the top will suffice. If I'm told by experts that adding a mattress cover should protect my home from fiberglass, I will just keep the nectar. If that's the case, suggestions on mattress covers would be appreciated (knowing I'm going to get an adjustable bed in the near future).

3 companies I'm finding nothing about fiberglass in their construction online are:


If anyone has suggestions on what mattresses don't contain fiberglass, but are similar to nectar premier, I would love to have some help figuring this out. It feels like everywhere I look it's some sponsored individual paid to sing the praises of one mattress over another. Or multiple people arguing about whether fiberglass is there or not.

Most of the stories I see online are anecdotal and I suppose in fairness they could be constructed by the competition. I just don't know who or what resources to trust anymore. I just want a good night's sleep and to keep my family safe. Is that really too much to ask?

My fiancé bought an eLuxury mattress 5 years ago and won't sleep on any thing else. Now, we're moving and we want a bigger mattress. But, eLuxury is out of stock for 3 months and I am impatient. Do you recommend any similar/better mattresses?

I went on Temourpedic chat box, they said that Cloud Elite Breeze is similar to LuxeBreeze Firm. Try LuxeAdapt Firm too. Try LuxeBreeze Soft and PrpBreeze medium while you at it.

Luxe Adapt Firm is my favorite….but pick what you like.

The best thing would be to search craigslist and Facebook marketplace for the same mattress. Sometimes they are new. Some are used. I would not be scared of used. Most use a mattress protector and you will use new sheets. Have you stayed at a hotel? You slept on a used mattress.

With current line of Tempur, check out Luxe Adapt Soft and ProAdapt Soft. Also, ProAdapt medium and Adapt line.

I have ordered the tempurpedic mattress topper (3 inches) and 2 inches of latex soft and medium to test them both out.

I was about to order springs but then I saw Arizona and Latex mattress factory do not offer returns on those. Can I just buy a spring mattress like www.walmart.com/ip/Linenspa-Explorer-6-Innerspring-Mattress-Twin/620841013this and call it a day?

Hi there,

I have a Tempur-Cloud Elite Breeze from about 12 years agio. At the time we bought this mattress it was the second softest model available in the Cloud line, with the cloud Luxe softer, and then the cloud Supreme being one level firmer than ours.

It’ll soon be time to get a new Tempur-pedic and I’m having trouble finding a mattress similar in support and depth and softness to our mattress, but our mattress is perfect for us and 12 years ago we spent many many hours testing mattresses to choose it.

I’m wondering if there is any way to figure out which current model or models are the closest to the one we have, so that I can at least narrow down our search. When I go to a mattress store and try Tempur-pedics none of them seem to feel like ours felt when we first got it. To make it extra confusing, some of them are called the Elite, but they feel nothing like our mattress feels and are designated as medium firm, while our mattress was designated as extra soft. I realize ours will have changed a lot in 12 years, but my partner and I both remember more or less the feeling of it, and why we chose it, and we’re striking out on finding its twin. I’d be so grateful for any advice!
