Boat Seat Swivel Set

Purchased new from this site 2 months ago. Selling because it doesn't suit my fishing style.
The seat comfort is very good, and I was able to enjoy my fishing trips relaxingly, but it was so comfortable that I ended up dozing off during my trips and couldn't concentrate.
I've only used it for 2 fishing trips since purchasing it, and I don't believe there are any tears, damage, or discoloration. There are some minor scratches from use, but I think it's still perfectly usable. Please judge from the photos.
There is a belt to secure the backrest when folded, but the snap seemed weak, so I modified and reinforced it.
The swivel plate? also rotates without any issues.

There are no bolts or anything else; the photos show everything included.
Thank you.
