Do not buy this mattress, the coils gage size is not good enough to support anyone...it was poorly designed and you will never get a good nites sleep!Now i'm understanding that there has to be at least a 2 in sag in the mattress before they will do anything, with no weight on it. Please tell me how they come up with this, the whole point is sleep comfort. They inspect your mattress with no weight on it and a ruler, how would you know it the mattress sags even more without any weight on it! Simmons is terrible!
