This product is a set of plastic bed risers. There are 8 pieces in a pack, each standing 3 inches high. The external dimensions are 4.25 * 4.25 * 3.3 inches, while the internal size is 3.25* 3.25* 0.5 inches. The square-shaped risers are made of a sturdy material. Their surface features high-tech printed wood grain, which not only avoids issues like moths and wood thorns but also makes them light yet strong. They can support heavy-duty furniture up to 2200 lbs. With a stacking design, these bed lifters can provide a 3-inch elevation, and you can stack them to increase the height further. They are suitable for various furniture items such as desks, chairs, sofas, couches, tables, cabinets, and beds. Using these risers makes it easier for the elderly to get in and out of bed, provides extra storage space, and allows vacuum cleaners or robot vacuums to operate more flexibly. Color: Brown.
