Karimoku Rotating Leather Natural Leather Desk Chair XT4310AJ

Karimoku Swivel Desk Chair with Casters

I purchased this item used, so I'm unsure of its condition when new, but I will describe it based on my experience.
There are some dirt and scratches on the leather surface.
I'm not sure if it originally had a clear coating, but there are areas where the shine is not very noticeable.
It swivels and reclines slightly, but there is rust on the damper.
There is a slight noise when swiveling at low speeds (possibly due to lack of oil?).
It also seems to be a feature, but the seat sinks slightly when you sit down and returns when you stand up.
The model number sticker is missing from the side, so the model number may be incorrect.
It has not lowered on its own while I've been sitting on it so far.

I plan to pack it with bubble wrap and cardboard.

This is a used item, so please only purchase if you understand this.
