Heavy Duty Carbon Steel Material: Made of heavy-duty steel and felt furniture pads, these risers can support the weight of heavy furniture in your home or office, safely holding up to 1,000 lbs. Protect floors and enjoy durable bed lifts that won't crack like other risers. Lifting Height 3cm & Create Extra Space: These risers lift heavy furniture up to 3cm smoothly and safely without causing dents or cracks on hard floors. Increased furniture height allows for more under-storage space and easier cleaning underneath, ideal for use with robotic sweepers and vacuum cleaners. Self-Adhesive Foam Pads for the Top: Self-adhesive foam pads help secure furniture to the risers, preventing slippage. The risers feature felt pads on the bottom to protect hardwood floors, reduce noise, prevent scratches, and avoid leaving marks. No Noise, No Scratches: Daily movement and use of furniture can damage hard floor surfaces. These risers help protect hardwood, ceramic tile, and linoleum floors from scratches and scuff marks. Felt padding provides floor protection, operates quietly, and leaves no residue. Suitable for All Furniture: A set of 4 furniture risers fits round furniture legs and can be used to raise desks, chairs, sofas, castor-equipped furniture, and beds. Designed to support heavy furniture while protecting your floors and creating additional storage space.
