Everlasting Comfort Memory Foam Seat Cushion

This is a set of a backrest and seat cushion.
I purchased it on Amazon and used it for about 10 days, but it didn't fit my body, so I'm selling it.

The manufacturer's outer box is not included.
There are no noticeable stains or sagging.
Immediate purchase OK.
