The effective sleep surface is only the middle 2/3rds of the matress. The outside 1/3 slopes downward, and wants to roll a back sleeper off the side.

Very comfortable-We have only had it for 6 days. So far we have enjoyed the product.

Just got this mattress.

Just got the mattress and pillows today. Still allowing it to air.

My wife got medium I got the firm with adjustable beds we love them.

Good ,not sure after a year or years, but so far it's pretty good for me for 3 months

The most comfortable Masters I’ve ever spend time on!

Hopefully gets some good night sleep
