Designed to securely raise most types of furniture, these stackable risers can be stacked together. Stacking it together is easy, insert the top of one riser into the bottom of another riser, and they will securely nest together. For safety reasons, it is recommended that no more than 3 risers be stacked together under each furniture leg. Each riser features a specially designed recessed holder top that holds all types of furniture legs that are at a foot, furniture panels/bases, and bed rollers /casters. Built strong to support even the most massive furniture, each riser can support 1,000 pounds. These bright and low-profile risers are perfect for raising low-sitting furniture like desks, tables, couches, and sofas; these low-profile risers are also high for creating extra storage space under beds and dressers. Safe on all floor surfaces, the removable rubber o-ring on the bottom of each riser protects floor surfaces from damage and provides a non-slip grip to keep supported furniture firmly in place. Includes 8 clear risers that are covered by a 5-year free replacement warranty and a 1-year commercial warranty. Please note that all wheels on bed frames must be in the caster slots to ensure a stable hold. Not recommended for use on high-pile carpets.
