【Adjustable Clamp System】 Set of 4 furniture and table leg risers, 10.2 cm (4 inches) long, for an extra height of 100 mm (4 inches). The table leg extensions fit table legs from 0 to 1.5 inches (0 to 38 mm) thick. You can adjust the spacing of the furniture frame as needed and tighten with the included screwdriver. 【Not Easy to Fall Off】 Our chair and table leg risers come with adjustable screw terminals and use clamp fasteners to securely attach to the frame and will not fall off when lifting and moving furniture. Unlike other taller furniture risers with grooves, but without clamping devices, where even small movements can destabilize the riser and cause the furniture legs to fall. 【Adds 4 Inches in Height】 Set of 4 furniture risers in black or brown, space-saving risers for beds, tables, and sofas, sturdy furniture risers for bathroom cabinets and desks. Create an extra 4 inches of storage space under the bed. Raising the bed makes cleaning under furniture easier, especially for robot vacuums.

【Sturdy Bed Riser】 These furniture risers are made of a sturdy, super strong, and durable material. 4 units combined can easily lift up to 4400 lbs (2000 kg). Not only suitable for raising beds and mattresses, but also perfect for raising nightstands, sofas, tables, desks, cabinets, and shelves in homes and offices to provide you with legroom for extra comfort. 【Protect Your Hard Surfaces】 The bottom is designed with felt pads. Daily use and moving of furniture can damage hard floors. These furniture risers protect your wood, ceramic, and linoleum floors from damage and scratches.
