Be careful when you lay it out. Check and make sure that it has been rolled evenly. Mine was crooked and when it started to open (on its own), it began to tear. It has a 6 inch tear but it is on the bottom foam and at the foot, so I am not going to worry about it. I HATE mailing things back. BUT, what a comfortable night I had. It is absolutely wonderful. The pressure areas on my hips bones have not hurt one time since I have been sleeping on the topper. I would highly recommend it!!!
