This was the first time I've ordered a mattress in a box. I usually get them from a store where I can see/feel them, but an expensive mattress and box spring wasn't in my budget right now. The mattress arrived on time, was well packaged, and was easy to get in place. It's not too heavy, just bulky and awkward to maneuver. I'm 5'3" and 65 yrs old and got it inside and upstairs by myself.There was no smell, and it reached the full height in about 36 hours. I was worried that it might be too soft, but the mattress is really comfortable. It has just the right amount of firmness that I don't have pressure points on my hips and shoulders like my old gel foam mattress, which makes for pain free mornings. I can't speak to the cooling layer, as it has been very cold at night here, but it doesn't seem to be as warm as my old mattress.The fit is perfect for my full size platform bed and it doesn't move around. I would definitely purchase this mattress again.
