Warnings and disclaimers
Disclaimer
Urethane foam will burn if exposed to an open flame or other sufficient heat source. Do not expose urethane foam to open flames or any other direct or indirect high temperature ignition sources such as burning operations, burning cigarettes, space heaters or naked lights. Once ignited, urethane foam will burn rapidly; releasing great heat and consuming oxygen at a high rate. In an enclosed space the resulting deficiency of oxygen will present a danger of suffocation to the occupants. Hazardous gases released by the burning foam can be incapacitating or fatal to human beings if inhaled in sufficient quantities. Once ignited, urethane foam is difficult to extinguish. Foam fires that appear to be extinguished may smolder and reignite. Always have fire officials determine whether a fire has been fully extinguished.

Returned at 6 months
Mattress seemed OK at first. I returned it at 6 months. It had no support on the edges and seemed to be "shrinking" in height. Outer cover was actually gathering along the bottom all the way around, which to me indicated it was compressing overall. I actually could feel some springs in one spot when I slept on my side. I'm not a little fellow ( 6'2" and 220 lbs) but should not have felt springs. When I sat on the edge of the bed, I could feel springs poking at the side of the bed. This was my second bad experience with "mattress in a box". I'm going to go back to a regular mattress.
Lumpy, more plush than firm
This mattress is awful! The moment I lay on it I get nerve pain down my shoulder blade. Tossing and turning are normal with this squishy bed. Returning but Sam's makes it a hassle. I don't have a truck and their so called pickup partner AIT never leaves a message or callback number! I will be getting my money back, this mattress is a dud!
Horrible mattress
To start, the mattress didn’t even come with a label — no brand, no specs, nothing. That was the first red flag. The edges are extremely soft, like a pillow, and the firmness is nonexistent. It sinks in the center, even after rotating it, and we’ve had it for less than a month. Honestly, it feels like I ended up with a cheap Temu mattress by mistake. As bad as the mattress is, the return process has been even worse. I've been dealing with it for almost a month now, and there's still no resolution. This has been a frustrating and disappointing experience from start to finish. I would not recommend this mattress or seller to anyone.
