Hi Phoenix,
Yesterday I went back to Sovn here in Dallas. From what I can tell, seems to be very high quality stuff from Berkeley Ergonomics. I used to love their 8" 100% latex, but now that I’ve tried latex at home, I realize even their “A” soft model isn’t quite “snuggly” enough for me unless I also add the $1,000 topper. Even the softest was still quite firm and springy. And I’m learning that I do like a little more cush on top. But, I do need very good support underneath for my stomach sleeping.
I did have kind of a break through there yesterday. I really liked the Willow “C”- it’s firmer honeycomb coils on the base and 2" of soft talalay latex on top (25ILD I believe). That seemed like maybe a good amount of firm support underneath, but soft enough on top. She did say that you can return for a 20% restocking, but no one ever does b/c you have 60 days for starters to adjust your bed slats & layers to find the right fit if you don’t get it right initially. Even swap out the whole coil system for a different one or for latex, or softer/firmer top, etc… And then supposedly they do not soften or sag. They have a 10 full warrantly for NO SAG. It’s ~$3,400 for the king mattress with adjustable slats. Not cheap at all, but in the range with many of the Tempurpedics.
