Klas Adjustable Height Ergonomic Active Stool

This active stool helps to keep you from slouching as you tackle your projects in your home office. It's built with an aluminum frame and features a circular base that allows you to lean in different directions while forcing you to work on your posture to promote lower back strength. The round seat is upholstered and filled with foam for just the right amount of support as you sit. Plus, you can adjust the height of the stool using the ring under the seat and swivel a full 360°.
