Hi Fatboy,
Unfortunately … Diamond is a manufacturer that I really want to like (see this thread) because they “fit the profile” of better manufacturers and they are doing some good things … but they really make it difficult to like them because they haven’t been very communicative with me or other forum members that tried to find out some of the specs of their mattresses and they don’t always appear to provide the information to their retailers either. You can read a little more of my thoughts about them in post #2 here.
The specs you listed are missing some critical information including the thickness of the layers and the density of any polyfoam or memory foam in the mattress. It’s likely that the polyfoam in the comfort layers is in the range of 1.5 lbs and the same or higher in the base layers and I would “guess” that their memory foam is at least 4 lbs but guessing or speculation is “dangerous” and I really do wish that their specs were easier to obtain because I don’t think they are doing themselves any favors by making them difficult to find. As you know it’s not really possible to make any meaningful comments about their mattresses without more information.
With some of their mattresses such as the all latex Ethos here they disclose all the layers but with their mattresses that include polyfoam or memory foam they often don’t.
It looks to me like the Amor and the Relief both use pocket coils that are in parallel and the Escape uses nested coils. Other than that they do have different amounts of foam and memory foam and they may also have differences in how the layers are tufted or quilted. None of this though is really enough to make an informed decision.
It would be great if your retailer came through and found out the specifics of each mattress. If they do it would be great to post it here so that others will have the specs more easily available. I hope they are more successful than I was.
Overall my feelings about them haven’t changed much. I want to like them … I think they are making some better than average quality/value mattresses using some good materials and construction techniques … and I would rather make a blind purchase of one of their mattresses than a major brand. Unfortunately, I don’t feel good about making a blind purchase at all and I really wish either they or their retailers would be more transparent and make it a lot easier to like them based on fact instead of speculation.
