The first mattress sunk where I sleep in less than a year and was warranty replaced. I’m 220lbs 5’10”. We spun the mattress after 6 mo to see if it was just me and it did it again in different spot. Soun again and was still same from last spot. Second replacement mattress now after less 6mo same thing. Hoping they will do something about this one also. Don’t want another mattress from them though. It took a month to get them to pickup the old mattress. Laid in my garage taking up space the whole time
