A free-size cushion that gently supports a heavy lower back. I purchased this the other day and used it for two nights. I am selling it because it doesn't suit me. It can also be washed in your home washing machine. I think it's in a clean condition without any stains, so how about it for those who want to try it? *Returns are not accepted.
