High-quality material: The furniture legs are made of aluminum alloy, which is rust-resistant, anti-oxidizing, beautiful, and practical. They will not deform or fade, and their modern, simple style suits all types of furniture decorations. Excellent design: The base has a non-slip design for increased stability, and the height is adjustable (adjustable range: 3.78 to 4.1 inches), as well as the length (adjustable range: 0.8 inches). This allows them to remain stable even on uneven surfaces, providing you with a comfortable home life. Please check your size before ordering. Protects your floor: The ABC pad on the underside of the leg is non-slip and durable, protecting your floor and reducing noise when you need to move the bed or other furniture. It also prevents scratches on the floor. Easy to install: Simply screw these legs onto your base and enjoy. Compatible with headboards; just tighten them. You can replace/install the furniture legs at any time; simply remove the old legs and install the new ones for easy installation. Applicable scenarios: The adjustable bed legs are waterproof and moisture-proof and can be used on sofas, wardrobes, beds, TV cabinets, and other surfaces. They also do not rust, even with long-term use in bathrooms or humid environments.
