Precautions For 2 layer(3.7inches)and 3 layer(5.5inches)and 4 layer(7.2inches), the intermediate sections (excluding the top and bottom) are stackable. 1 layer(2inches) does not have an intermediate section and therefore cannot be stacked.

2In Single Layer, Flexible Stackable Height: Our furniture risers feature a single layer height of 2 inches, taller than standard 1.5-inch risers to deliver extra under-bed storage space instantly. Stack multiple layers freely to reach a max lifting height of 7.2 inches, perfectly solving the trouble of low sofas, beds and appliances.

Heavy Duty PP, 4000 LBS Weight Capacity: Made of thickened durable polypropylene resin, the 4-pack risers jointly hold up to 4000 pounds (equal to a 2-ton private car). Reinforced internal grid structure prevents cracking or deformation under heavy loads, safe for heavy beds, large sofas, refrigerators and washing machines without wobbling or collapsing.

Upgraded Anti-Slip & Floor Protection: Unlike ordinary risers with shallow top lips, we have adopted a design with a deeper, wraparound edge that effectively prevents furniture from sliding. Top surface with dense anti-slip textured bumps locks furniture legs firmly; bottom built-in thick TPU anti-slip rubber pad tightly grips hardwood, carpet, tile floors.

L-Shape Dual Design, Universal Furniture Fit: Unique L half-side dual-purpose design fits all furniture leg sizes: small round/square legs use the L half side; large wide legs use the full flat surface. Fits angular legs, round/oval feet below 6.85 inches, extra-wide legs by placing two risers side by side. Widely compatible with bed frames, sofas, chaise lounges, desks, dressers, washing machines, mini fridges and cabinets.

Tool-Free Install, Multi-Scenario Use: simply tilt furniture slightly and place legs onto the risers within minutes(Please see the image for detailed step-by-step instructions.). Extra clearance under furniture simplifies floor sweeping and vacuuming, expands massive hidden storage space for boxes and clothes.
