Our Heavy Duty Adjustable Bed Risers (4-Pack) give you 3 heights in one set – 3.5", 5", or a full 8.5" when stacked – so you can customize the perfect lift for beds, sofas, tables, or desks. Instantly create massive under-bed storage for dorms and small apartments, or raise your couch just enough for your robot vacuum to clean underneath every day – finally enjoy a truly spotless floor without moving furniture! Engineered with super-strong plastic and a 2000lb capacity, the extra-wide base plus rubber anti-slip pad keeps everything rock-steady while protecting your floors. The deep recessed cups securely grip bed legs, couch feet, or table legs up to 3.2 × 3.2 inches. Whether you need bed risers 8 inch heavy duty, couch lifters for height, table risers 6 inch (or more), or desk lifters/risers to level on uneven floors.
