• High weight capacity: With a maximum weight capacity of 3500lbs, the spring supports a wide range of mattress types and combined occupant weight.

• Easy assembly: Clear installation instructions and included hardware let most people complete setup quickly and without special tools.
• Anti-slip and silent: Seamless welding and a silent design reduce noise and movement when changing position on the mattress.
• Removable fabric cover: The fabric cover detaches for quick cleaning, simplifying upkeep in high-use spaces.
