Too soft, will not last, do not buy.

This is a hybrid between innner spring and memory foam. Having several Sealy Posturpedics in my lifetime with success, I had purchased based on the name and how it felt in the store. Less than 2 years in, this bed turned to mush and developed huge body impressions creating a high hump in the middle (think of a W shape almost). Needless to say, it has wreaked havoc on our backs. Do not believe the 10 year warranty. The only warranty is through the distributor you buy from, not Sealy directly (if you call Sealy, they will direct you back to the distributor), and their "independent" contractors told us the impressions were .25 inches away from being covered under warranty for a replacement (how convenient!). You can't flip this mattress either as it's one sided, the most you can do is move the head to bottom. As of 2 years later, it is even worse and we are getting a different bed. To me, $1700 for a bed that breaks down after less than 2 years and is totally unusable after 4 is a complete waste of money! Stay away.
