My mom has had an earlier model of this chair for over 10 years and it's still in great shape so I decided to get one for my home office. It helps my back so much which has been in worse shape now that I'm pregnant. It offers the support I need while sitting at the desk for long periods of time and it's a relief to sit in after being on my feet.
The seat has a wheel that doesn't fit in at all! It's also hard to hammer in with a hammer! And there were no tools to help people to use screws! Super poor experience!
