    1. WS15 Sit to Stand chair 5 Star Review

      Posted by on May 30th 2014

      Standing all day caused inflamed bursitis in my knee. I compared 5 different work stool and "leaning chairs", and this seemed the best bang for the buck. It's been fine for its purposes. In a confined space, the base seems quite large and is in the way, but in an open space this works very well, and allows for quick movement in and out of the office. It was a good purchase.

    2. Good product 4 Star Review

      Posted by on Dec 8th 2013

      Good comfortable chair, easy to adjust. It lets you work without getting "stuck" into a chair, making it hard to work while rising and sitting many times a day. The only negative was the solid black base, which matches the mat it is placed on, causing a trip hazard on rare occasions.

    3. Sit to Stand Stool 5 Star Review

      Great for the busy work environment and manufacturing style work that it is used for.
