After carefully observing the Bed frame I've noticed 3 of the legs were a bit short or maybe the flooring is unleveled.  Basically was not touching the floor has a tiny bit of a gap. Got the bed frame for the guest room and paired it up with a 10 inch mattress that fit perfectly up until the start of the upholstery head board. Just as I wanted. I'm please with purchase. It's a cute bed frame.
