Milliard 9-Leg Support System Heavy Duty Metal Bed Frame with Lockable Rollers/Wheels - Twin Thick frame construction provides ample support and resists bending or breaking while still retaining a semi-portable form factor. Center rail is supported with extra legs to reinforce every bed frame's weak spot: the middle. Most of the frame members interlock with pins and sockets for easy, but secure assembly. Recessed edges and end caps minimize accidents and maximize safety. Reinforced headboard brackets are designed to fit headboards of almost any kind.
