Got a kiddo (or an adult!) who just can't sit still? Instead of fighting the wiggles, harness them with the SitWell Wobble Stool. This clever stool has a rounded, unstable base that lets you gently rock and tilt while you sit. That constant micro-movement forces your core muscles to engage to keep you balanced, which strengthens posture and, surprisingly, can help improve focus and concentration. It's like a fitness ball, but more stable and with an adjustable height seat. Perfect for fidgety students in a classroom, for a home homework station, or even as an active sitting option for adults at a standing desk. The seat height adjusts easily from 15.7 inches to 21.7 inches with a push-button mechanism (it does require about 105 lbs of weight to lower it, so an adult might need to help a small child). It's sturdy, with a 250 lb weight capacity. It arrives fully assembled, is GREENGUARD Gold certified for good indoor air quality, and has safe, rounded edges. In a fun eggplant color, it's a tool that turns sitting into an active, beneficial activity. Help burn energy and build better sitting habits!
