These adjustable bed support legs are designed to provide the necessary stability for heavy mattresses, preventing bed slats or metal bed frames from bending or breaking. The legs can be adjusted to accommodate uneven floors, with an original height of 7.08 in. (18 cm) and a maximum adjustable height of 12.6 in. (32 cm). Crafted from high-quality steel with a multi-layer baking paint process, the legs are rust-resistant and durable. The upgraded feet base features a thicker and wider design for increased force area, reducing pressure and enhancing weight-bearing capacity. The legs come with rubber pads to prevent slipping, reduce noise, and protect floors. Installation is straightforward, with options for both pre-drilled and non-drilled bed frames. The package includes four adjustable bed legs, eight bolts, eight hexagonal nuts, and four mounting auxiliary plates, ensuring a secure and stable foundation for your bed. Color: Black.
