This set of four wooden bed risers is engineered for heavy-duty support, tested to hold up to 2500 pounds collectively, and coated with a double layer of wood wax oil for protection against moisture and mold. Each riser measures 4.13 inches in width, 4.13 inches in depth, and 5 inches in height, with an inner height of 4 inches and a default inner diameter of 3.07 inches to accommodate larger furniture legs. The set includes adjustable EVA rings that can be inserted to reduce the inner diameter to 2 inches with one ring or 1 inch with both rings, and the rings are trimmable for further customization to ensure a secure fit for various leg sizes. A 1-inch raised edge around the top helps prevent furniture from slipping or tipping, enhancing stability for bed frames, tables, sofas, chairs, or cabinets. High-grip, anti-slip pads on the bottom adhere firmly to hardwood, tile, or carpet, preventing sliding and protecting floors from scratches. The block-style design requires no tools for setup or removal, and elevating furniture creates additional under-bed storage space, facilitates easier cleaning, and can assist individuals with mobility needs by making it easier to rise from seated positions. The combination of durable materials, customizable fit, and substantial weight capacity makes these risers a reliable and functional solution for improving furniture height and accessibility.
