Pros

Cons

• −$300 is premium-tier — only justified if kneeling chair is a daily-rotation pick
• −Rocking learning curve more pronounced than fixed-base kneeling chairs
• −Cushions slide on the wood frame on aggressive rocking — secondary mounting recommended
• −Limited Amazon stock — direct-from-defydesk.com may be needed if Amazon shows out-of-stock
