Mattress comfort layers - Memory foam

31 May 2019 11:25 #51 by Mia12345
Hi Sensei,

Thanks again for the helpful offer to think about members who provide 3 or 4lb polyfoam layers or foam cores.

In the meantime, I've turned the Novosbed upside down to approximate a memory foam support core/base, but I can't imagine this is as effective as just buying an actual core/base? Or as affordable?

I've been trying to build up as suggested as similar to the previously loved Comforpedic:
-1-2 inches of less dense memory foam that's comfy (1.8 to 4lb),
-1-2 inches of polyfoam,
-then higher density 1-2 inches MF (5 or 6lb),
-then core/base.

As you pointed out, an issue might be that I only have low density polyfoam. I don't even know what the "16" and "23" layers I have are! The Novosbed Comfortplus topper is 1.8lbs, ILD 9 PF.

I haven't gotten to try any 19ILD talalay yet, but hope to soon. I think you're implying that this latex is an alternative to the 3 or 4lb PF idea?

Unfortunately, I'm feeling under the gun having to decide about the Novosbed within the sleep trial and given the new nerve compression that I can't shake, so all suggestions greatly appreciated!

Hi Mia12345,

Thank you for the post.
You are correct turning the Novasbed upside down is not going to be more effective than just buying an actual core base; it’s really used as a trial to see if you can approximate the mattress that is best for you.

The only caution I have is that be careful of the polyfoam layers that are not memory foam. As transition layers and a mattress they can be helpful but as you put them on top of a polyfoam they really are part of your comfort layers.

Regarding the 19 ILD talalay topper, I don’t really think of it as a replacement of anything in particular, more of these best latex comfort layer for pressure relief. If you had that, and 4+ lb. memory foam, I would use the Talalay above memory foam. These two material technologies, memory foam and latex act as excellent pressure relieving layers. Any miscellaneous polyfoam layers 1.8 or 1.9, 16 or 23. Etc....I think of what use are they. They can be good as a transition from base support core to comfort layers.

Understood on the Novasbed, I hate to ask this, as I don’t want to throw you way off, but in any of your retail visits have you tried any hybrid/latex or hybrid memory foam beds? Some members have excellent exchange programs for the topper/comfort layers, and the pocketed coil bases make for excellent support cores.

Thanks
Sensei

Thanks Sensei!

Regarding PF as comfort layers, I was just building off of the Comforpedic specs which list not-MF comfort layers and your suggestion to look into 3 or 4 lb PF, since what I have currently is too low density to work. If I'm understanding your suggestion correctly, then if any members sell 3 or 4lb non-MF, I'd be very interested in that!

I'll order a foam core to build off of, maybe medium (like 1.75 lb / 32 IFD like the Novosbed had) to be safe (since easier to make softer than it is to make something firmer with top layers). Sad that DIY lite hasn't quite panned out using the existing Novosbed Soft I had, but good to know that it has been feeling better using that approximation than back when I had an innerspring core.

I have laid on a bunch of hybrids at the stores and found them all to be "pushy" when compared to the not-hybrids -- even finding latex "pushy," but going to try to find some 19ild Talalay as you've recommended to test as a comfort layer.

Thanks again!

Hey Mia12345,

This sometimes can get very confusing my apologies if I sent you in the wrong direction. I do not think you should be looking for three or 4-pound polyfoam. I do think you should look for three or 4-pound memory foam that is a better approximation of the field that you had indicated you like.

Regarding the base foam core, it is recommended that 1.8lb is the minimum density. 35IFD is good. Noted on the hybrid mattresses I remember now. Noted on the latex mattress, you are not the only one that has this "issue" with latex.

Let me know if that makes sense.

Thanks
Sensei

Hi Sensei,

Yes, I definitely was barking up the wrong tree based on your previous post. This is confusing stuff!

So:
-lower density MF
-higher density MF
-low density polyfoam or latex if I find one that's not too "pushy" as transition layers
-foam base

If you know any good posts that go through DIY memory foam bed recommended build specs/ advice, I'm all ears. Hoping to make this quick and painless. Will try to approximate the Comforpedic as much as possible given that there were no details on densities or ILD...Thanks!

Hey Mia12345,

So I was looking back at the brochure, and wanted to look at the layers again...so I then decided to see if I can find some other ILD info. So I googled "aircool transflexion core" and I found some other sites discussing this mattress from 2013/14/15...but I also found websites that have it for sale still, but I am sure they are not available.

I want to find exact specs on this bed, it now bothers me, because this foam is readily available I am sure..I will message you if I find something from a Simmons executive I know pretty well. We'll see.

I also decided to google "Comforpedic Advanced Rest Luxury Firm" again....and on this Amazon link (product unavailable, of course) I found these specs:
(Bold - good info / Red - no density info)
(Ignore the Edge support, no way you could replicate that)


Features: • 9.5” High • 9.5” CPA Zippered Bucket • 9.5” CPA Core • 1” 4.0 AirCool Memory Foam with TruTemp Gel1” Firm Comfort Foam2” 4.5 LB AirCool Memory Foam2” Independent Support Technology3.5” AirCool Transflexion Core • 1.65 LB 45 ILD AirCool Edge Support

I will message again a couple of days, also have you checked out Foamorder.com for different foam densities/MF, etc?

Hi Sensai,

Thanks for looking into this again! That's good intel!

Just to make sure I'm understanding - the 1” Firm Comfort Foam must be polyfoam that's not memory foam (or else they would have just said "memory foam")? Which is another reason why I was thinking of sandwiching MF, other foam, MF in my layers.

It looks like the company Future Foam made the foam in the Comforpedic, but I didn't see a way to tell which of their still-available toppers would be related. And per previous post, they weren't able to provide Comforpedic details (told me to call Simmons) when I called (but did seem very nice).

I did buy a 1 inch 4lb from foamorder based on posts I'd read. It feels nice enough and could definitely get other layers there as needed.

I finally found a 19 ILD Talalay topper to try. It was definitely different than the Dunlop, but still felt too pushy/bouncy to warrant spending the money. Good to try though!

Fingers crossed that your Simmons contact has more ideas!

Hey Mia12345,

Yes, the 1" inch would be polyfoam, or else they would say memory foam...totally correct.

Sometimes these days companies are using "fast response" foam which is more like memory foam but not as "slow recovery"...and good quality for pressure relief...but that's not what we are talking about.

ok on foamorder...and I totally understand about the pushy bouncy 19ild...glad you could see it was different. No worries.

Have not heard from Simmons friend...so possibly early next week.

Talk soon, sorry about the delay in getting back to you.

Hi Sensei,

Thanks again! I'm feeling a little stuck as the Novosbed was returned and I'm now back on the springs bed, which just doesn't work for me. In an effort to make things easier, I had asked the local custom mattress guy to just purchase me a foam core to build off of, per previous advice. But I just found out that he didn't and instead has a MF bed for me to try upside down as a core that is cheap/basic/with no density or IFD info. Given that folks discuss DIY mattresses here, I imagine there must be places to get a foam core and know specs of what you're buying, so I'm not sure why he didn't just do that as asked...but honestly, I'm having trouble finding a good source on my own. Any advice on where to find a good quality foam core?

Still hopeful you might get additional intel on some of the comfort layers from the Comforpedic in case we can purchase/replicate as well. But, I imagine the base is the least finicky component and something I can try to find in the meantime.

It's pretty rough sleeping here so thanks again!

Hi again,

Apologies, I totally missed the "conventional foam blocks" option on Foamorder, which I have to assume is basically a core for DIY. I'll plan to just call Foamorder to choose the kind of foam to select for my needs (and what I can find in past TMU posts using that company).

Is there a TMU guidance page with suggestions for DIY foam mattress? For example, do I need a cover on that block...

This is all based on the assumption that using a core foam block makes more sense than purchasing a MF mattress and turning upside down per previous discussion.

And I'll still keep my fingers crossed on your contact. I think you were hoping they'd have leads on where to get MF layers similar to the Comforpedic, but from your last post, maybe you are saying not to worry/hold my breath about the polyfoam layers in between? I guess I'm confused because if I was trying to get close to my previous experience, that would require polyfoam comfort layers too?

As always, thank you! I hope I'm not incoherent from lack of sleep :)
