What this product does: Stabilizes and levels bookcases, sofas, tables and other household furniture to eliminate wobble, reduce noise and prevent tipping. Protects floors by creating a firm, nonmarring contact between furniture legs and floor surfaces. Key features and benefits: 20 pcs composite wedges: Includes a set of 20 wedges so you have enough pieces for several items or multileg adjustments. Colors included: black, white, brown for discreet placement. Durable construction: Made of longlasting plastic material that resists deformation and maintains integrity under heavy pressure and varied load conditions. Antislip performance: Trapezoidshaped design with a textured surface prevents slipping and holds furniture securely on hardwood, tile or carpet. Stackable shims: Wedges can be layered incrementally to achieve precise leveling. They are easy to trim or break down to the exact thickness you need for a clean look with minimal exposure under furniture feet. Versatile compatibility: Designed to work with most furniture legs, feet and bases—suitable for different shapes and sizes without special tools. Simple to use: Slide a wedge under the low leg, stack additional wedges for fine adjustments, then trim or break away excess for a nearinvisible finish. No drilling or mounting required; repositionable as needed. Typical applications: Level a bookcase on an uneven floor to stop shelves from tipping and reduce rattling. Stabilize a dining table or desk so chairs don't catch and the surface remains steady. Prevent a sofa or armchair from rocking on carpet or partially uneven flooring. Practical notes: Suitable for indoor household furniture stabilization and floor protection. Keep spare wedges from the 20piece set for future adjustments or multiple rooms.
