Customer Reviews

I luv my new chair !! Review by Jesse Rivera
We use this product in our security office. It serves two purposes. The first is our guards sit tall and this in itself is a deterrent to thieves and people who would mean us harm. Second, it provides an ergonomic relief for a post that requires alot of time in a chair. Our guards have given us the thumbs up for thier new chair. (Posted on 5/11/2014)

"Great Chair!";-) Review by Willaume Kelley IV
Due to prior neck/back/leg injuries I have a 42" elevated workstation desk and this chair works absolutely perfectly to accomodate sitting comfortably at my workstation throughout the workday!However, I would like to see a newer model with a screwthread hole on the seat pole, so the knob tightener (???) will stay put and readjusting the footrest, (it slips from time to time), throughout the day (Posted on 5/11/2014)
Looking forward to buying a second one Review by Linda Boarman
I'm a Dental Technician that experiences back problems from a vehicle accident and found in this chair great support as well as great comfort as I sit at the bench up to 12 hours a day. (Posted on 5/11/2014)
