Overall works great and is comfortable. The mattress is very firm. We have a memory foam topper for guests who would like a softer bed. The knobs constantly fall off or come loose. They are a little tricky to get to since they are under the mattress and you need to try put them on with it open (so the knobs are then facing the floor). But otherwise, no issues. Be aware - this is SUPER heavy and a beast to move.
