Sinks

Me and my husband are not over weight we are healthy BMI and this mattress sinks in significantly in each side we sleep on with a hump in the middle I have to roll up on to the hump To his side so cuddle him. I have back pain we are both side and back sleepers. I opted pillow top as I had a posturepedic medium pillow top that did not cause these problems until after having for 10 plus years.
