It took a couple of days to realize how much I like my new Wave mattress. I was used to a firmer feeling mattress so I wasn't quite sure that the soft, cozy feeling was right for me. Then I realized that I was sleeping better without getting overheated and that cozy feeling was good for my stress. Now it's easier to convince myself to go to bed, and I sometimes lounge in bed in the morning with the head up, reading and snoozing. It's a winner.
