I like the GhostBed. For me, it's extremely comfortable to fall asleep in and feels supportive. The material is dense and I actually think the cooling technology works. I was worried because my partner and I are both on the heavier side in terms of weight and I've had an online hybrid mattress before from a different company that was just way too "sink-y." GhostBed does much better at that, but I did pair it with a heavy duty bedframe to give it as much help as possible. The main reasons for 4 stars instead of 5 are that (1) in the morning I do feel like I'm a little sunken into the bed (although falling asleep feels great) and (2) the edge support, especially at the corners, isn't great. Actually, the edges never popped up all the way after unboxing. Not sure how that will do over time. Like other reviews said, the free pillows are great! They're so cold after they've been sitting for a while they almost feel wet. We may order more.
