The Anthros seat is 19.8" wide, with a contoured cushion designed to distribute pressure evenly β not just support a fixed width.
What that means in practice:
The seat edges are softly contoured rather than hard-sided, which makes the effective comfort zone more generous than the measured width alone. Many customers with hip widths in the 19β21" range report a comfortable fit.
Our honest take:
If you're close to or above the seat width and want to be sure, our 60-day risk-free trial is the most reliable answer. Try the chair in your actual work environment. If it doesn't fit, we cover your return β no questions asked.
