RRI Goods Ergonomic Kneeling Chair, Posture Support Comfortable Padded Office Desk Chair, Angled Rocking Stool & Balancing Seat, Natural Relief for Neck or Back Pain

It supplements an ergonomic rocker-kneeler I've enjoyed for 35 years. The instructions for assembly were not as explanatory as I would have hoped. On the whole, it is still a clever and highly effective, posture-conserving device for sitting at my PC desk.

I love the chair, and I am pretty sure that the broken part was a fluke. It’s comfortable (I have back problems), sturdy (I’m not a tiny person), and not overly complicated to put together.However, one of the wooden dowels was broken off in the chair; I contacted the seller through Amazon and have heard nothing back.
