I got my mattress. It's apparently not fireproof and it's very springy and bouncy (not motion isolating) and sinks in just a little bit. It feels very supportive and cloudlike but on the firm side. I'm 270 lbs and I would say that's the weight limit for one single sleeper on a queen. It's very bouncy with a tiny bit of softness. The sleep surface is silky smooth. The edge support is decent but not the very best. I like it better than my old one but I'm not sure if I would pay $650 again for a mattress that's not fire proof, this firm, and not motion isolating. It's supposed to last at least 5 years and it has a "forever warranty". So if you get a 1.5" indentation they may repair or replace. I
You just have to keep it clean with no tears or stains, which I got a mattress protector for. I'm supposed to rotate it every 2 months due to my weight of 270 lbs, but I may end up returning it due to it being too firm. I tried the hybrid in store and enjoyed that more, but I'll probably go with a different mattress brand entirely at this point. I want something cheaper and more plush, with motion isolation and edge support. I thought about a mattress topper but am not sure that would solve the firmness. I've slept on it one night and it didn't relieve my pain.
