Some beds have a mechanism that uses gravity and friction to keep the bed upright, but if your bed is too heavy or the mechanism isn't working properly, you may need to fix it. One way to do this is to attach small rubber pads to each of the bed's leg posts, then flip the bed over so that the feet are pointing toward the ceiling. Next, peel off the backing of the rubber pads, stick one on the bottom of each leg post, and flip back over the bed. Now, your bed should stay up thanks to its gripper pads!
