Actually, I'm pretty disappointed.  The chair itself is crooked and when you sit it not only is a little lopsided but also tends to lean you forward like you're being ejected.  However, I have a very handy husband who put some spacers under the front and fixed the forward part.   It's still a little lopsided, but I can live with that.  I really do like the adjustable aspect... that works fine.  I guess it all goes back to "you get what you pay for."
