The Groove Adjustable Stool was designed to reduce squirming and shifting by providing the comfortable sweet spot immediately. The ergonomic seat encourages a proper working posture when facing forward or to the side so that the student can settle quickly and focus on learning. The high-density polypropylene shell has a gentle flex in the back to continue to provide support for the student who reclines. The generous waterfall seat front supports circulation in the student’s legs and feet.
