I can't really say how this box spring will hold up since I just received them and put them on our guest bed and no one has slept on it yet. I did not notice that although I put them on a queen bed there seems to be a bit smaller. Until I put the mattress on (it should arrive next week) I don't know if it will work out ok. But it did arrive in tact in two large boxes. I like the split queen box springs better because they are easier to handle when you have to move, especially if the staircase is narrow.
