Need specs for Stearns and Foster Ava Rose hybrid mattress

[phoenix]

Hi missy_

I did not initially see your link to the Pure Latex Bliss specs (I see it now) so I emailed them to ask them about that and what was meant by the term “bonded foam.” I asked for ILDs for the layers of latex in the Nature and Beautiful and I may have asked about the Mezzanine as well (even though it is a hybrid). I received a reply today from Pure Latex Bliss about the ILD ratings and it stated: “Thank you for your inquiry, but our beds are not built to an ILD rating, they are built to a PLUSHNESS level, which you will find on our website. The Beautiful mattress is a very plus mattress and the Nature is a medium plushness in the scale of offerings. The Mezzanine is a hybrid and an altogether different feel. The best method for finding what speaks to you personally is to ³test drive² them. Purchasing our beds is a very personal experience and finding the right bed for you requires time on the beds themselves.”

I agree with them that the ILD’s are not necessary and mostly meaningless when you are testing a mattress in person (see post #39 here) and it’s not important to know them although the specs that are listed in the post I linked are accurate. Your own careful and objective testing for PPP is all that really matters. You can also read more about their bonded foam core in post #6 here.

Anyway I now see your post about the Pure Latex Bliss ILD ratings, although I am not certain why Pure Latex Bliss did not provide that information to me.

Most likely because they know that the ILD specs aren’t important and that they would end up confusing consumers who try to use “comfort specs” to choose a mattress more than relying on their own careful testing and experience and that these types of “comfort specs” would tend to confuse most consumers more than help them.

I have been busy doing more shopping. I went to a store today that sells MLily memory foam beds. When I got home, I found a post you made about MLily here.

So the ones I was considering do have bamboo charcoal in them. They are Certi-Pur. They definitely feel a lot different from a Tempurpedic Rhapsody Luxe but they are also a lot cheaper. The memory foam (but from what you stated the “actual” firmness of the memory foam may be altered by the fillers they use) on the models I was most interested in is:

Serenity:

0.5 inches of bamboo infused memory foam quilted into the cover
2.0 inches of M48 “high density” memory foam (quotes are mine; as far as I can ascertain from googling, M48 appears to possibly be 4.8 pounds. Did not find this on their website but from somewhere on google.) (If it is 4.8 lbs, is it possible that the actual foam itself may be less dense since their foam contains things like bamboo charcoal?)
3.0 inches of M36 memory foam (I think this is 3.6 pound foam but again, not certain)
7.5 inches of higher resiliency base foam

They talk about a “semi-open cell structure” with their memory foam. Info on their website.

Bliss:

1.0 inches of bamboo infused memory foam quilted into the silk blended cover
1.5 inches of GelCore gel-infused, maxiumum cool high density memory foam (do not know how dense this is)
2.5 inches of M48 high density memory foam (I think this is 4.8 pounds but again that is a best guess on my part)
2.0 inches of UltraCore HD premium high density rebound memory foam
8.0 inches of higher resiliency base foam

It is not possible to tell from these descriptions what the exact foam densities are. I do not know if any of them are “high density” like 5.3 pound or 7.1 pound. The retailer did not know and I do not see it on the MLily website.

The third bed I considered was:

Vitality: This was the firmest bed and it may not have enough memory foam? (3" I think not including the cover)

1.0 inch of bamboo infused, heat dissipating memory foam quilted into the cover
3.0 inches of M36 (this may be 3.6 pounds from googling; not sure) memory foam featuring naturally renewable plant based oils
7.0 inches of higher resliency base foam

Perhaps you know more about these specs than I do? I will try to find more information.

You can read some general comments about mLily here and there is some information about the Bliss in post #3 here and my reply in the following post and about the Vitality in post #2 here but I would always make sure that you know the quality/density of all the foam layers in any mattress you are considering. If you can’t find out this information or the retailer you are dealing with isn’t willing or able to find out or confirm it for you (which is part of the job of any good retailer) then I would pass the mattress by. If you can find out the information you need (see this article) and post it on the forum for any mattress you are considering then I’d be happy to make some comments about the quality of the materials in the mattress or let you know if I see any obvious weak links in the design.

There are many other options in the memory foam list in the tutorial post besides the ones you mentioned that you aren’t comfortable dealing with that would also be well worth talking to.

I’m looking forward to finding out what you end up deciding and or course any other questions or comments you may have along the way.
