Pay a little more, get a lot more

I am a terrible sleeper. I toss and turn all night. Mostly on my side, but I never really know how I will wake up. This mattress was researched very heavily. There were less expensive options but the reviews led me to this one, especially after the sale service. The mattress came rolled up but unlike others that claimed they needed up to 72 hours to fully inflate, this mattress was ready to go within minutes. The comfort is superb but after a couple of nights, I am able to state that I needed it for a long time. I felt less sore in the morning. I still toss and turn, but nowhere near the amount I did prior to this mattress. It's one of the best purchases I ever made.

Good but lacking in one area.

I purchased the 12 inch queen in Firm, it’s not quite as firm as I was expecting however it’s still nice. My only complaint is both ends are lacking on support for sitting to say put socks on. The sides have great support however. All in all I’m happy with it so far.
