awful!!!! after 2 months sleeping on this mattress we hated it. My husband's side of the bed sags way down ( wt 190) my side as well sags way down ( my at 110lbs!) we called to get the situation rectified the representative came out to the house measured the sag in the mattress instead it was considered normal. we continue to complain to bobs, which we spent over 4000 dollars in their store on furniture, and we were told there's nothing they could do. all the furniture we bought in from them is all falling apart. you definitely get what you pay for steer clear of bobs!!!
