Small, but my little neighbor loves it
It's a great product, unfortunately, I'm a great sized woman and it didn't fit my bottom or my managers desk chair, I weigh in about 220 lbs.  So I would definitely not make the mistake I made,  and pay close attention to the measurements, my thighs hung off the sides and it was very uncomfortable,,, HOWEVER,,, my next door neighbor is in her late 80's and has had a broken back.  She's a little tiny lady and she LOVES THIS.  It really brings her a lot of relief on her back when she is knitting.  She uses it actually to lean back on, not sit on. Too small for me though, and too small for the managers office chair
