I was hesitant about buying a bed in a box but I am pleasantly surprised by the comfort of this mattress. I have constant hip pain and was looking for a bed with a little bit more cushion than a pillow top spring mattress as I am a side sleeper. No matter which position I am in this mattress feels great and I don’t have any hip pain at all while sleeping. Only downside I found is that it does get a bit hotter than a spring mattress but I do tend to sleep hot. Also the edges sink down a lot if you sit on them. Other than that I am thrilled with my purchase.
