I have an injury that has made sleeping and finding the right mattress very difficult. With the number of professional athletes promoting this brand and the promise of restorative sleep, I had high hopes. Unfortunately, this is one of the the most uncomfortable mattresses I have ever slept on. It's so hard, I don't know how it could be restorative for anyone. My injury got significantly worse during the required 30 night trial, and I'm currently sleeping on an air mattress because it is the better option. Can't wait to get this thing out of here so I can get something else. FYI: While everyone in customer service is really nice, returns/refunds are not as quick/simple as they make them sound.
