Best bed frame I've ever seen.

extremely easy to assemble only takes about 5 minutes. it fits a twin a full and a queen mattress. the centerpieces slide and snap into the correct size that's marked on the piece. the sides fold out including the legs already installed. extremely well put together very strong. I would recommend this to anyone. and it will hold a headboard sold separately it just folds out and you bolt it to the headboard.

Adjustable and Easy Assembly

I needed a bed frame in a hurry when I had guests coming to stay, and this one was exactly what I was looking for. I already had a mattress and box spring, so I just needed a sturdy frame that would fit and could be assembled quickly. The adjustable twin/full/queen design made it easy to get the right fit, and assembly was straightforward with no surprises. Once put together, the frame felt stable and securely supported the bed. For the price, I think this is an excellent value. If you already have a box spring and need a simple, reliable bed frame, this is a great option that gets the job done.
