- Casters: Periodically check the casters for any accumulated debris (e.g., hair, dust) and clean them to ensure smooth movement.
- Fasteners: Over time, screws and bolts may loosen. Periodically check all fasteners and tighten them as needed to maintain stability.
- Cushions: The three-layer elastic sponge cushions are designed for durability. Fluffing them occasionally can help maintain their shape and comfort.

- Chair wobbles: Verify that all screws and bolts are securely tightened. Ensure the chair is placed on a flat, even surface.
- Casters not rolling smoothly: Inspect the casters for any obstructions like hair or debris and remove them. Lubrication may be applied if necessary.
