Abstract: A urethane cup having a slot in the middle covering and completely enclosing the bed frame wheels and shaft to keep you from stumping your toes. Near the bottom of the cup is a slot which the wheel sits in. The remainder of the cup is for the shaft protection. The slot may be formed during the manufacturing as a removable unit, so the cup can be used selectively on bed frames and shafts. A simple application: lift frame and set wheel into cup slot. The lip at the opening must be extended for added safety.
