Mattress comfort layers - Memory foam

Thanks, Sensei!

I'd love to order from a TMU trusted member, but am just having trouble finding ones that ship to US with memory foam toppers of the kind you were suggesting (have 4lbs/4.5lbs covered with two in that range already). Very open to suggestions.

Searching around Amazon for 5 lbs, I see these brands:
Memory Foam Solutions
DreamDNA

There are other options for 3 lbs, which I don't currently have either. Places where you can try out memory foam toppers would be awesome!

Is there anything to take into account when deciding which MF mattress to use as a "base"? I'm within the sleep trial still, so could return the Novosbed if it doesn't seem like a good "base," especially if it's better to just buy an actual foam base/core.

I guess I meant not progressing because under the 2 to 3 toppers will be the comfort layers of the Novosbed, which are less dense than the topper above it. But, if this is normal DIY light, as you say, then that works for me! Again, complete lack of adventure here :) and interested in following successful footsteps of others so as to be comfortable again asap. If you've seen other posts like mine, please link away. I tried to search the forum, but haven't come across anything.

I think I found a local store with a Talalay 19ILD topper so I'll try to get there (but low hopes given how I've felt lying on Talalay mattresses).

As always, thanks for listening!

Hey Mia1234,

Thanks for the post. I see what you mean on the 5lb topper from USA members. I believe the MFS would be perfectly fine to try, and the Amazon return process is consumer friendly.

Just a point of reference, the 19ild Talalay when used on top of a memory foam topper will provide a feel that is different than the "Talalay mattresses" you had tried in the past. I am not sure those were the best "latex feels" out there.

Regarding the base mattress, what was the Amerisleep mattress model that you also have. I think the model with the more "durable" base would probably be the better choice. Forward it to me again, and I will try to look at the differences in these two.

Thanks,
Sensei

Hi Sensei,

Thanks!

I've purchased the MFS 2 in. 5lb topper.

It's the Amerisleep AS4. But, my sleep trial done in a couple weeks, whereas I have some more time with the Novosbed to try out the newly ordered layers. In terms of feel, the Novosbed is more uniform and "firm," whereas the AS4 does some weird arch-thing in just my lower back.

Here are the Novosbed specs as provided by them:
Soft:
1" - 3.7lb / 8 IFD - 5th generation high-density gel visco-elastic memory foam
1" - 1.95 lb / 9 IFD - 5th generation premium airflow foam
2" - Plush 2.5lb / 12IFD - 5th generation open-cell pneumatic memory foam
7" - 1.75 lb / 32 IFD - Premium support foam

Does it make sense to stick some not MF/polyfoam layers in between the MF layers? I have two different 1 inch polyfoam layers. It's funny to think that before this I thought of beds as one uniform object and now they only exist as layers.

Thanks again!

Hey Mia1234,

Well, even though we know it is "layers in a mattress", you are right in a way as they are all connected together, laminated together, making up one single feel, with everything working together. So when adding toppers to a mattress......it really is like adding to one unit. So for the sake of the DIY lite, don't worry too much as to exactly what the top layers are in the Novosbed, and just build up your one or two layers on top.

Also, you may want to try the toppers under a mattress pad, and under the fitted sheet? Are you doing this already? Sometimes mattress pad can firm up your toppers a little...which may be a good thing, just food for thought as you "test" more.

Thanks, Sensei! That makes sense. I am trying them under the fitted sheet and some of the toppers have comfy covers on them too.

If you end up with any thoughts about Novosbed as a "base," just getting an actual foam base, or trying harder to make the Amerisleep a base, I'm all ears! Thanks again.

Hey Mia1234

Just fyi, once you mentioned the Amerisleep gave you some kind of "arching" thing, I didnt really compare the two products. I did do a quick lookup on the Amerisleep AS4 and I have to say that I don't really even know what this layer is:

ENHANCED "FEELS-LIKE-YOU'RE-FLOATING" LAYER

The Affinity layer with Surface Modification Technology (SMT) is our ergonomic transition foam. It has “zones” that provide extra pressure relief in key areas like the shoulders and lower back, along with precision-cut channels that carry away even more heat and moisture. It’s enough to make you feel like you're weightlessly resting on a cloud.



It may be that this "zoning" they have in this layer, does have too much firmness and/or pushback on your hips/lower back area. It seems like this may not be the right one to try to improve as we may be trying to overcome other variables that don't work for you. Just my thoughts after taking a look at the Amerisleep AS4.

Have a good weekend.

Hi Sensei,

Thanks for the thoughts on the Amerisleep - that makes a lot of sense!

I wanted to circle back to the question about buying a polyfoam core/base vs building off the existing Novosbed. I felt like I was on the right track, but yesterday was one of the warmest days we've had this year and the bed felt completely different. I woke up with nerve compression/tingly feet :( I know temperature changes MF feel, but it seems a bit much to have winter vs summer versions of my bed layers!

Mostly, I'm wondering if the 3 inches of MF in the top comfort layers in the Novosbed aren't stable enough to build on, since they're so impacted by the warmer weather (1" - 3.7lb / 8 IFD and 2" - Plush 2.5lb / 12IFD)?

Would it be better to build on an actual polyfoam support core? If so, I'm having trouble finding a list of places to get a core/recommendations on polyfoam cores from TMU (might not be searching for right keywords...).

Or should I continue to focus on the few inches of MF I'm adding on top? Last night, it felt like I was going right through the top MF comfort layer/topper....again maybe bc of the warmer weather. When MF gets warm, I think that means that my whole body "goes through" or compresses more (not just the heavier hips/butt) and hits the firmer layer underneath, in which case, I'd want to add in another comfort layer to cushion? I really wish I understood the physics here more!

Thank you again!

Hey Mia,

You do point out the memory foam and temperature issues, it is a fact with memory foam that warmer temperatures do cause the foam to soften much quicker.

Your logic about starting out and building on a "foam core" is theoretically better than trying to manage an existing mattress as a base. And then the "traditional memory foam" temperature issue will be there going forward. I was hoping the "DIY lite" may help relieve some of the short term issues.

I am going to check a few of the members and see about the core, if not then you may have to order from one of the recognized foam suppliers. I will forward some of these links later today.

Thanks
Sensei

Hi Sensei,

Thanks so much!

I'm curious if there are any general principles for how to adjust layers when seasons change and seeking a greater understanding of what actually happens. Is the issue that the MF compresses more in warmer temperatures (hence my feeling of going " right through" my top comfort layer)? If so, do people just add in an additional comfort layer when the weather gets hotter? Should this be something that is similar to what they had already - just more of it so as not to "go through" - or something firmer, softer? If polyfoam is less reactive, then is adding an additional layer of that the way to adjust vs MF?

As always, thank you! I did a quick count of how many iterations/combinations of layers I've tested in just the last few months and lost track around 55....I'd like to believe we're in the home stretch here! Just feeling like my sensitivity to the temperature change has thrown a wrench in.

Happy weekend, Mia12345

Hey Mia1234,

Happy Memorial day weekend to you.

You make an interesting point about memory foam and what people do during different seasons? Quite frankly I believe the majority of people just get used to the changes, either the dramatic or the subtle ones and don't adjust at all.

There is some really good information about memory foam in this article, that you may or may not have read.... memory foam pros and cons .

If polyfoam is less reactive, then is adding an additional layer of that the way to adjust vs MF?



Yes, in theory, this is correct but the issue is is that poly foam that is 1.8lb or 2.0lb density is used as a support core and are not as advantageous as comfort layers. What is becoming more popular are the approx 3.0 to 4.0 lb polyfoams that are an instant recovery that act more like latex foam, and are not as temperature sensitive as traditional memory foam. I am not sure if any of members sell this type of foam as toppers. I will be looking at some of their sites today and will let you know if I see any of this kind. Did you get to try the 19ild Talalay?

Thanks again, I really hope we are close.

Sensei
