My son's 100 yo house could take no other type of box spring up those narrow stairs! Perfect fit carrying the box up. Not too heavy. So easy to unfold to make correct size. When you put the zipper cover on have the frame not completely open flat. Or else the corners are too tight a fit to comfortably add the fabric cover. I thought I was clear in ordering the regular size but we got the low rise. Double check! I had customer service place the order and could have sworn we did regular. He has the unfolding foam mattress which is rather thick so it's not too low. But he would have preferred the higher profile. Not worth returning. So far so good. Can't comment on the longevity. It's only a week old. Wendy. Ocean, NJ. Thu Oct 15 2026
