Great mattress and expanded to 18” and is firm. For the price it’s worth the purchase. I didn’t let it expand about 72 hours before use.

I wouldn't buy this again. It sinks in too far when you are not sleeping alone. We've had it maybe a week now.

The media could not be loaded. When the write up says very heavy item, trust me it is. Once you get it out of the box and it could just be me I couldn’t tell where to start opening it so with my luck, the mattress was upside down and I had to flip it in the bedroom that was just about big enough to hold it, but I got it. It’s on a metal base 18 inches high and the bed is 18 inches high. You do not need a box spring as of right now that could change in the future, but everything looks good.

This mattress turned out better than I expected for the price. It has a nice balance - firm enough to feel supportive, but with just enough softness from the gel layer to stay comfortable. The edge support is solid, so you don’t feel like you’re going to slide off if you sit or lie near the edge. It also sleeps cooler than I thought it would, which is a big plus. It came well-packed, expanded quickly, and had only a slight smell at first that went away in a day. Overall, a good, firm mattress that feels supportive and comfortable.

Not firm and springs are shaky. Just opened 2 days before will wait and see if it gets better, mostly not.
