HI Phoenix, two models in the Evosleep line by Sherwood seem to meet my PPP. The first one, the memory foam one, would appear to be slightly better on paper. The second one felt great and is apparently very popular based on my calls with retailers, but may have a few weak links as you can see, albeit minor.
It was hard to get exact specs from my local retailer, likewise when I even spoke to a rep at Sherwood, who did not give out the specs “for proprietary reasons.” It took several calls to different retailers to get the specs from their documents.
Anyway, onto the mattresses. About me: I’m 6’1" and 160 lbs – kind of a beanpole figure. My comments are in parentheses.
Conforma Cool Perfection Luxury Firm Gel 5.0
(This choice was Phoenix-approved in post #6 here, although the specs were just slightly off, but approval was given for the accurately detailed firmer 3.5 version in post #6 here, which uses the same quality ingredients.)
-Super heavy weight lycra knit ticking with Outlast technology
-100% natural and chemical free barrier sock, wraps the entire foam core (Not sure why the term “sock” is used only on their memory foam models.)
-A layer of H.D. gel-infused cool memory foam: 1" @ 3.7 lb (Please note this is not the same as the biomedical gel used in their Biomedical Gel Rx Series)
-A thick layer of H.D. memory foam: 1.5" @ 5lb
-A layer of H.D. transitional memory foam: 1" @ 4lb (specs actually say 1" of VX13400, but this was Phoenix-indicated as 4 lb in post #6 here.)
-A thick layer of H.D. memory foam: 1.5" @ 5 lb
-A 6" foam encased soy-based H.D. foam support core: 6" @1.5 lb / 28 ILD: (not sure what they mean by foam encased foam)
Biotemp Ambiance Luxury Plush Euro Top
(I realize the two top layers of quilt foam come close to or perhaps surpass the limits of being acceptable. And while I realize there can be good latex hybrid mattresses with minority latex content, the fact that there’s just under 2" of latex in a 13.5" mattress of multiple layers of regular foam gives me pause. Still, it felt comfortable, and as I said, it’s apparently popular.)
-Heavy weight circular knit cover infused with Outlast technology for temperature management
-100% natural and chemical free fire barrier
-A layer of hyper-soft soy-based quilt foam: 7/8" @ unknown weight / unknown ILD (The Sherwood rep told me they don’t use any foam below 1.5 lb, but when I asked if that included the quilting layer, he said “no”; based on a Phoenix estimate on the Harbor Plush model described in post #6 here, it could be 1.2 lb. And while the Harbor Plush is a lesser model than the Ambiance, the other specs listed in the above post seem to indicate it would be the same quality stuff.)
-A layer of hyper-soft soy-based quilt foam: 7/8" @ unknown weight / unknown ILD (See above comment.)
-A thick layer of natural phase change celsion latex: .9" @ 21 ILD
-A thick layer of H.D. super soft soy-based comfort foam: 1.5" @ 1.5 lb / 15 ILD
-A thick layer of natural talalay latex: .9" @ 19 ILD
-A super-thick layer of H.D. soy based support foam: 1.75" @ 1.5 lb / 23 ILD
-A super-thick layer of H.D. soy-based support foam: 1.75" @ 1.5 lb / 23 ILD
-A 3.5" layer of super H.D. soy-based upholstery grade convoluted foam: 3.5" @ 1.8 lb / 32 ILD
-A layer of H.D. firm soy-based support foam: 7/8" @ 1.45 lb / 40 ILD (The 1.45 lb spec seems weird being taken out to the hundredths place, especially given the Sherwood rep’s comments about not using below 1.5 lb. Same thing about some thicknesses being listed as 7/8" and .9". Apparently .9" qualifies as “thick” but 7/8" does not in Sherwood’s books. Even the 1" layers in the Conforma Cool above are not described as “thick.”)
Thanks for your time and attention!
