What are the best methods to prevent thermal expansion noise in metal ottomans?

Thermal expansion noise in metal ottomans can be annoying, but there are effective ways to prevent it. First, ensure proper assembly by tightening all screws and bolts regularly, as loose fittings can amplify noise. Applying lubricant like silicone spray or wax to joints and moving parts reduces friction and minimizes sound. Placing felt pads or rubber stoppers between metal surfaces can also dampen vibrations. Additionally, keeping the ottoman in a stable environment with consistent temperature helps prevent excessive expansion and contraction. For long-term care, consider using anti-rattle pads or insulating materials to absorb noise. These simple steps will help maintain a quiet and comfortable piece of furniture.
