There's a very high lip around the edge of the seat that cuts into your thighs making it too uncomfortable to sit on for even a short time. It did earn a star back since the base design was close enough to the chair I was replacing that I was able to use the seat from the old chair with the back/headrest from this chair.
Buy this if love methly isocyanate. It is toxic and they used excess when making the foam. I am letting it air out in the garage for the next month in hope that the toxic chemical smell goes away.
