The SitWell Adjustable Stool provides a flexible seating option for the classroom, library, office, or home learning environment. Active seating supports the body’s natural need for movement. Seats that rock, swivel, and tilt encourage good posture, core strength, and alertness. Constant small movements increase blood flow to the body and brain aiding concentration. Ideal for children and adults who have restlessness, ADHD, ASD, or sensory sensitivities; dynamic seating can help sustain attention and focus by creating an outlet for fidgeting and wiggles. Featuring a rubberized textured seat and a convex base lets you rock 360° and helps keep you upright. Seat height adjusts from 15.7" to 21.7" with the push of a button; it requires a minimum 105 lbs. to adjust the seat down. GREENGUARD [GOLD] Certified for low VOCs and CPSIA compliant.

You and your kids deserve the absolute best for a brighter way to play, share, learn and grow.
