Adjustable clamp mounting system: 2 inch furniture raiser and table raiser, increases height by 50 mm. The table leg extension is suitable for desk legs with a thickness of 0 inches to 1.5 inches (0 - 38 mm). You can adjust the distance to your furniture frame as needed and tighten with the included screwdriver to prevent wobbling. Secure fit: Unlike other furniture risers or bed risers with grooves but no clamping mechanism, which may become unstable or detach with minor movement, our bed risers feature a clamp bracket that securely holds the frame in place and stays firmly attached when lifting or moving furniture. Increases height by 2 inches: Set of 4 furniture feet, brown furniture lifters, ideal for beds, tables, desks, cabinets, bathroom vanities, and more. Adds 2 inches of clearance under the bed, creating extra storage space and making cleaning underneath easier—especially convenient for use with robot vacuum cleaners. Durable construction: Made from strong, durable materials, these furniture risers support up to 5000 pounds. Suitable not only for beds and mattresses but also for nightstands, sofas, tables, desks, cupboards, and bookshelves at home or in the office. Enhances legroom and improves comfort. Protects floors: Designed with felt pads on the bottom. Helps prevent damage to hardwood, ceramic tile, and linoleum flooring caused by daily use or moving furniture.
