Perfect for Slim Furniture Legs: The adjustable bed riser planks feature a round design that effectively adds 3.1 inches in height. These heavy-duty risers are suitable for furniture legs with a round diameter not exceeding 1.8 inches and a square edge length not exceeding 1.3 inches, such as beds, sofas, coffee tables, desks, cabinets, washing machines, chairs, and refrigerators. Resistant Materials: Our round bed furniture riser tubes are made from resistant ABS high-quality plastic and non-slip rubber, ensuring great stability. Each set of riser tubes can support heavy furniture weighing up to 6000 pounds, securely holding the furniture without wobbling. Non-Slip and Shock-Absorbing: The top of the bed leg riser tube features a triangular cone design to prevent slipping and stop furniture from sliding left and right. The bottom of the 3-inch furniture riser has a TPU non-slip rubber design that protects the floor from scratches and reduces vibrations and noise. Adjustable Design: The bed riser tubes can be stacked to adjust the height and can be easily assembled to the desired height. Using two layers together adds 8cm (3.1 inches), while using just one layer adds 5.3cm (2.1 inches). This expandable space under beds and furniture facilitates storage and cleaning. The round design makes it easier to match the riser tubes with furniture legs. A More Comfortable Life: Bed riser blocks not only provide you with more storage space under the bed but also help improve sleep or relieve back pain. Heavy-duty bed risers are an ideal choice for raising low-profile furniture, aiding in the process of transitioning from sitting to standing. This is a quick and easy solution to help those with mobility issues get up from the bed or sofa.
