Best Praise
+2 pts“comfort option is pretty much all I recommend now being able to dial precisely into the bed you want vs fumbling around different brands cost competitive, and as top/upper layers wear down, just need to replace those at a steep discount they offer vs an entirely new mattress”

+2 pts“Degree of plushness is in the eye (or whatever) of the sleeper, and what feels firm to me (92 pounds) might feel plush to a 200-pound person: the more you weigh the farther you'll sink in. With that in mind, I've found my Comfort Option C-SER-35 plus additional one-inch "C" topper to be just soft enough. It's one of the softer - maybe the softest - builds they offer. Others here have posted that they've found all the Comfort Option line to be too soft - which was a good recommendation for me, to whom most things I tried in stores felt much too firm. The one I bought has a 2" (plus 1" topper) copper memory foam layer on top, with a 2" serene foam layer in the middle, and a 6" layer that I think they consider "medium" (35 ILD) bottom support layer. It comes in a box and I found the company easy to work with. Good prices. No affiliation yada yada.”
