QWORK® 4 Pcs Bed Mattress Retainer, Non Slip Holder, Stopper, for Solid Panels, Wooden Frames

Material & Size: Made of flat, thick metal with a black rust-resistant finish. Each mattress retainer measures approx. 26 x 8 x 9 cm. Please carefully check the product dimensions, the available mounting area and your mattress size before purchasing. Suitable Bed Frames: Designed for installation on flat, solid wooden bed panels or wooden bed frames. This product is not a universal fit and is not suitable for metal frames, upholstered bed frames, hollow panels, or bed frames without a solid wooden surface for screw mounting. Installation Requirements: The holders must be fixed with screws directly to a stable wooden surface. Please ensure that the wooden panel is wide and strong enough for installation. Pre-drilling is recommended to help prevent the wood from splitting. Mattress Retention: The raised metal bar helps keep the mattress in position and can reduce movement during use. Please confirm that the 9 cm height and 26 cm width are suitable for your bed structure and mattress before installation. Package Contents: Includes 4 mattress retainers and mounting screws. The included screws are intended for wooden bed frames only; depending on the thickness and material of your bed frame, alternative screws may be required.
