Black - Adjustable Bed and Furniture Riser with Screw Clamps, Heavy Duty 4" Sofa and Table Riser, Fits 0.8" to 1.6" Chair Legs.

【STURDY PLASTIC MATERIAL】These sturdy, adjustable furniture legs can support even the heaviest furniture in your home or office, up to 20,000 lbs (9,072 kg). They won't creak like other stair legs. High-density felt pads protect your hardwood, ceramic, and linoleum floors from scratches and wear. 【SECURE SCREW LOCK - NO TIPPING】You don't have to worry about the furniture leg tipping over. Other furniture legs often lack sufficient support, causing them to fall easily. To solve this problem, we've equipped the adjustable furniture leg with a screw lock. The 3cm-deep groove is recessed to prevent the legs from tipping over. The screw locks make it easy to adjust and secure the furniture leg: the included furniture legs remain securely in place. Easy to install on sofas, armchairs, tables, and adjustable desks. 【Adjustable Chair Leg Width】 - The 5cm high furniture leg risers fit round or square leg diameters (22mm to 42mm). Total height: 83mm, added height: 52mm, side length: 52mm. Additional notch protection: 30mm. Note: Not suitable for legs less than 22mm or more than 42mm wide. NOTE: Not suitable for curved or adjustable chairs, only for right-angle chairs. 【Added Height】 - These risers not only create more storage space under the bed, but also provide more room for a vacuum cleaner or robot vacuum. They also make it easier for the elderly to get in and out of bed. They raise heavy, fixed furniture such as beds, sofas, chairs, tables, armchairs, etc. by 1.75cm (2/4 inch) to prevent shoulder and neck pain caused by furniture that is too low. [Protect your floors from scratches] The bottom of the sturdy sofa legs is made of high-density felt. The felt pads protect your floors from scratches. The smooth, stable edges firmly support the weight without causing dents or cracks in wooden surfaces. This protects hardwood, tile, and linoleum floors from scuffs and scratches.
