Surprisingly sturdy! It was hard to find a bed frame that wasn't super low-profile, but this actually has about a 7" clearance if you want to store things under it. Took off a star because the slats are 4" apart (mattress companies recommend slats be at most 3" apart for support) and because the stabilizing legs in the middle of the bed don't all touch the floor. Took 2 of us about 2 hours to put it together.
