We have used this mattress almost every night for 14 years and have been completely satisfied. Love that this mattress can be flipped because it is two sided and will fold to get through awkward places if needed. Comfort This mattress is very comfortable. Support It is an ultra-plush but still offers support that we need. Firmness Firm enough for us yet still plushy soft. Durability We've used this mattress and box spring set for 14 years and just now are noticing that we are rolling to the edge of the bed at night so the middle is less used. We are considering buying another one and we are looking into the prorated warranty.
