The backrest rotates more stiffly than it used to. How do I maintain it?
After using the TXTR CH9 chair for a long time, the backrest rotation has become sluggish, and the user is looking for a way to maintain it at home.
Since lubricant is applied to the inside of the backrest rotating parts, if the movement has become stiff from prolonged use, you can apply commercially available grease for plastic.
Lubricant is pre-applied to the internal parts designed to rotate the backrest[1]. If you use the chair for a long period, the lubricating component may wear out or dry up, causing the backrest rotation to become stiffer than it initially was[2].
Grease is a high-viscosity lubricant that reduces friction when parts mesh and move. General anti-rust lubricants for metal can damage plastic, so you must choose a product specifically for plastic.
When movement becomes sluggish, applying commercially available grease for plastic into the gaps of the hardware will restore the original smooth rotational feel[3].
Specific recommended product lines for plastic grease or standards for the application cycle have not yet been confirmed.
