Sleekform East Austin Ergonomic Kneeling Chair with Back Support - Winter Linen and Wood Ergo Stool for Desk - Best Ergonomic Kneeling Office Chair for Posture and Leg Circulation

My 7 year old son does use his desk quite a bit - voluntarily. He's currently at it re-reading the Poodle books from Michael Clay Thompson and giggling. He also will go over to his desk at times to do his math or handwriting or just to draw or write on his own. Anyway, he stole my desk chair. I got myself the below; it offers movement without the swivel or scootability of typical office chairs. He adores it. (I did too, before he snagged it.) https://www.amazon.com/Sleekform-Austin-Ergonomic-Kneeling-Support/dp/B0DGLSBJT5
