Adjustable bed and furniture risers with clamp, heavy-duty 4-inch chair risers for sofas, tables, and chairs, suitable for square/round chair legs from 0 to 1.5 inches in diameter.

【HARD PLASTIC MATERIAL】 Adjustable furniture risers made of durable hard plastic, capable of supporting the weight of even the heaviest furniture in your home or office, up to 9,000 kg. They won't crack like other risers. High-density felt pads protect your hardwood, ceramic, and linoleum floors from scratches and scuffs. 【UPGRADED SCREW CLIP & ANTI-FALL】 Don't worry about the bed risers falling. Other chair risers have insufficient grip and can easily tip over. To solve this problem, we've equipped the adjustable bed risers with a screw clamp, preventing them from tipping over. Use the screw clip to adjust the fit; The wrapped furniture legs are drop-resistant. Adjustable sofa/table/desk risers are easy to install. Step 1) Clean the table leg and keep it dry. Step 2) Align the chair legs in the center. Step 3) Use a hex screw to lock them in place. Adjustable Chair Leg Width: The 10.2 cm bed and furniture risers fit round or square legs from 0 mm to 37 mm in diameter. Total height: 134 mm, actual height increased: 103 mm, side length: 52 mm. 【GENERATE USEFUL SPACE】 - Add height under beds, making it easier for vacuum cleaners or robot vacuums to operate. They also make it easier for the elderly to get in and out of bed. Increase the height by 50 mm on beds, sofas, armchairs, tables, couches, and other heavy, fixed furniture, thus preventing shoulder and neck pain caused by low furniture height. 【PROTECT YOUR HARD FLOORS FROM SCRATCHES】 The base of these sturdy sofa risers is made of high-density felt pads. The felt pads protect your floors from scratches. The robust, smooth edges safely support the weight without damaging or cracking hardwood or other hard surfaces. Protect your hardwood, tile, and linoleum floors from marks and scratches.
