Hi san0844,
The specs they provided “translate” into these (from the bottom up) …
The support core has two 4" pocket coils (the specifics of the coil count and gauge aren’t mentioned) which would be a total of 8". They have double edge guards for edge support.
The padding and insulator layers above the coils (to protect the foam and wool layers above from sinking into the coils and even out the compression of the coils) includes the resinated textile pad (shoddy pad) of unknown thickness, 7/8" of firm 1.5 lb density foam, and the cotton batting (of unknown thickness). These are probably a little over 2" in total and there would be no weak links in any of them used in the deeper layers of the mattress.
The Eurotop over the padding and insulator layers includes 4" of wool and 2" of Talalay latex which along with the fabric is 6.5". These are both high quality materials.
The panel is the cover and the quilting material and has 1.25" of 1.5 lb polyfoam, a layer of dacron (polyester) fiber (unknown thickness) and the fire barrier so this is probably a little over 2" as well. These are on the lower quality end of the scale.
The specs don’t mention the type of fabric used in the cover.
All of these (8" pocket coils, @2" insulator and padding, 6.5" eurotop, @2" quilting panel) add up to about 18.5" which is about the thickness of the mattress so it seems that none of the layers or components are missing.
There is @ 2" of lower quality/density materials in the quilting (the polyfoam and the dacron) which is a little more than I would normally be comfortable with but this is quilted and tufted which would precompress the material and help them maintain their loft and add to their durability.
The Eurotop with 4" of wool and 1" of Talalay latex on each side will also compress somewhat over time (wool generally compresses by about 30% of its thickness) but the tufting and the latex on each side would precompress the wool and also help the wool maintain its loft and help to minimize the impressions. Some impressions are a normal part of a mattress that has thicker layers of wool which will maintain it’s resilience even when it has compressed. The impressions can also be evened out by sleeping in the center of the mattress from time to time so that the comfort materials compress more evenly.
These top 8" or so (the quilting panel and the eurotop) would be the part of the mattress that would be most subject to developing some impressions over time and this would be a normal expectation for this type of mattress but because of the materials and the design this shouldn’t have a significant effect the comfort or support of the mattress.
In other words … while the mattress may develop some impressions over time … they will tend to even out to some degree and this wouldn’t be a weak link with a mattress that is tufted and uses a larger amount of natural fibers in the comfort layers.
As an interesting aside … you can see the main “selling point” of how this mattress is marketed to retailers in this picture (“the highest profit ultra premium collection in the industry”) which of course is why retailers like it so much.
This type of mattress is more of a “luxury” than a “necessity” and it may not be any better than another mattress in a lower budget range that uses the same or higher quality materials in terms of PPP or how well you sleep. In many cases with this type of mattress purchase, how you feel “about” the mattress can be a more important part of your personal value equation than how well you sleep “on” the mattress. I would make sure that you make some careful comparisons both in terms of PPP and your personal value equation so that you are satisfied that the more premium price is worth it to you and there is a compelling reason to choose this mattress over another one that is also a good match in terms of PPP but is in a lower budget range. If there is a significant difference between this mattress and others that you have tested and you aren’t only going by “showroom feel” and “appearance” and a mattress that is as much about luxury as it is about PPP and quality of sleep is important to you, then it would certainly be worth considering or at least comparing with other similar types of “luxury” mattresses.
