I'm experiencing sagging, less than one year of sleeping on this mattress. Just to note, I'm an 102# female.

After 10 months mattress has holes on both sides. Both my wife and me are so sore each morning. Should have sent it back.

We have had the mattress for about one week. We are truly amazed how we feel getting out of bed in the morning.

[This review was collected as part of a promotion.] It started to deteriorate after the second night and got worse. Would not recommend to anyone.

This is the ultimate mattress, been trying to find a true ultra firm, tried others and returned, this is defined the one, highly recommend
