I admit I was a bit skeptical about buying a Mattress In a Box without trying out in a store first, however, I have loved this Wave Hybrid King Split Mattress since the first night!  It is super comfortable, and I absolutely love all of the features including the infinite adjustable head and feet positions, easy to use remote, the massage feature and nightlight.  I just want to stay in bed all day!   The adjustable head and headrest are great for reading and watching TV in bed ... no more need to prop up 3 pillows to do that.  And the whit glove delivery was tops!  One of the best purchases I have ever made!
