This chair is just OK... I chose it because most kneeling chairs seem to have pretty lukewarm reviews. A few issues: First, the assembly instructions were wildly confusing and unclear and I'm fairly handy. The backrest isn't secure so it flips back and forth which is annoying if you ever want to drape a sweater on it. Second, the lever to adjust the height is RIGHT where your foot sits, so I accidentally adjust my height multiple times throughout the day. Otherwise, it's comfortable and the fabric seems to be of fine quality. We'll see how it holds up.
