Fast and easy. It's that simple. Adjustable components render this bed frame completely tool-free for set up. We use nothing short of railroad grade steel in our bed frames to ensure that the proper and most durable support for your mattress set is provided night after night. Rug roller wheels for carpeted surfaces are included. The frames are available in all sizes and the queen features 5 legs while the king has 6 for the correct amount of support for all bed sizes. *Glides for hard sufaces also available.
