The Monster Bed Frame is hands down the strongest bed frame available. Nicknamed "The Monster" for its scary strength, this heavy-duty bed frame can support a tremendous amount of weight. The secret is in the frame's TWO inch side rails. They literally double the strength of the frame! The Monster is a 5 in 1 bed frame. It will adapt to any size of bedding including California King. Are you ready to put The Monster under your bed?
