Black - Adjustable bed and furniture riser with screw clips, 4" heavy-duty sofa and chair table riser, fits chair legs from 0.8" to 1.6".

【HARD PLASTIC MATERIAL】 These sturdy, adjustable furniture risers are made of hard plastic and can support the weight of even the heaviest furniture in your home or office, safely holding up to 20,000 lbs. They won't creak like other risers. The high-density felt furniture pads protect your hardwood, ceramic, and linoleum floors from scratches and scuffs.【Secure Leveling Screw Clip and Won't Fall Off】 You don't have to worry about the bed riser falling. Other furniture risers don't have sufficient grip and are prone to falling. To solve this problem, we've improved the adjustable furniture riser with a screw clamp. The 3 cm groove is recessed, preventing tilting. Use the screw clips to adjust and secure it, and the wrapped furniture legs won't easily fall off. Adjustable sofa/couch/table/desk risers, easy to install. 【Adjustable Chair Leg Width】 - These 2-inch bed and furniture risers fit round or square leg diameters (22 mm / 0.8 inch to 42 mm / 1.6 inch). Total height: 83 mm / 3.3 inches, added height: 52 mm / 2 inches, side length: 52 mm / 2 inches. Additional notch protection: 30 mm / 1.18 inches. Please note: Not suitable for legs less than 22 mm (0.8 inches) wide or greater than 42 mm (1.6 inches) wide. NOTE: Not suitable for curved or reclining chairs, only for right-angle chairs. 【Add Extra Height】 - Not only do these add extra height for under-bed storage, but they also provide extra height for your vacuum cleaner or robot vacuum for more flexible operation. They also make it easier for the elderly to get in and out of bed. Increase the height of heavy, fixed furniture such as beds, sofas, chairs, tables, couches, etc., by 2/4 inch to prevent shoulder and neck pain caused by low furniture height. 【Protect Your Hard Floors from Scratches】 The bottom of the solid sofa legs is made of high-density felt pads. The felt pads protect your floors from scratches. The solid, smooth edges can hold the weight firmly without causing dents or cracks on hardwood or other hard surfaces. Protects your hardwood, tile, and linoleum floors from marks and scuffs.
