If you are in the market for a bed frame, look no further than this amazing item! The Modern Sleep Universal Heavy Duty Bed Frame is one solid and sturdy piece of furniture. The quality is amazing (especially for the price) and I feel confident that it will serve my needs for many years. To be more specific, the bed frame has a double rail center support bar that is different from any other one I have had before. It runs from end to end, or head to foot, not side to side like other frames I have had. Also, the frame is adjustable to fit any size bed—twin, full, queen, king, and California king (they include an extender bar for use with California king size mattresses). To me, this is being mindful of the customer's needs and I appreciate that point tremendously! It comes almost completely assembled, you only have to attach the center support rail, which was very quick and easy, and they even include a small wrench to use in the assembly. This is another important detail that shows their consideration for the consumer. You don't even have to rummage through the tool box, everything you need is included. I can't say enough about this top quality bed frame. I would recommend it to everyone.
