Bought this mattress last fall/winter, very comfortable at first but within 1-2 months noticed that center caving in even with rotating mattress as instructed. My husband is 160# and I am 105# so we are not overweight but this mattress very quickly broke down and became terribly uncomfortable. We both feel like were falling into the center. Removed mattress and resurrected our old mattress from guest room and we are both much much more comfortable.
