Comprehensive Protection: The adjustable threaded bed frame anti-shake tool with EVA cushion can effectively reduce noise and protect your walls from damage. It can prevent the head of the bed from shaking and let you sleep at ease. Adjustable Height: The bed frame stopper only needs to adjust the length of the headboard bumper and screw the headboard wall protector into place, which can easily change the distance between the bed frame and the wall and keep the bed frame stable. Various Uses: This adjustable threaded bed frame anti-shake tool is widely used for objects with unstable center of gravity or easy to shake, such as cabinet beds, chairs, sofas and so on. Easy Installation: Our bed stabilizer against wall does not need to be drilled into the wall or headboard. Tear off the round sticker and stick to the bed frame, then tighten the screws and adjust the length until the black EVA end is against the wall beside the bed frame.
