6-Pack Metal Anti-Slip Mattress Spacers - Stable mattress support: Keeps the mattress in place and prevents slipping, reducing the need to readjust during the night. - Adjustable width compatibility: The adjustable width design fits a wide range of bed frames with a maximum width of 96.5 cm. Suitable for most bed frames. - Scratch protection and secure fit: Locks the mattress to the bed frame while protecting the frame from scratches. The recessed pan-head screws are gentle on the mattress and minimize the risk of scratches compared with knurled screws. - What’s included: Six metal spacers for stable, even support. - Practical applications: - Use on platform or slat bed frames where the mattress tends to shift at the edges. - Use on adjustable or modular frames to accommodate varying widths without changing components. - Use in guest rooms or shared beds where multiple bed styles may be used, ensuring a stable mattress across different frames.
