The SitWell Adjustable Stool by ECR4Kids provides a flexible seating option for the classroom, library, office, or home learning environment. This active seat can help decrease the need to fidget caused by back strain and as a result, improved focus, and attention. Backless design helps encourage proper posture. The rounded anti-skid bottom lets kids and adults rock 360° - which help engage and strengthen your core. Rubber base also helps protect your floor from scratches. Customizable 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.
