Does the B100 Pro have a headrest?

No. This model has a mesh back without a headrest. Sihoo sells separate headrests for some models, but check compatibility before buying one.

What is the weight capacity?

The chair is rated to 300 lb maximum weight.

Can I adjust the seat depth?

Yes. The seat slides forward and back, which helps shorter and taller users get thigh support.

How does it compare with the Sihoo Doro series?

The Doro chairs add features such as a headrest and more elaborate lumbar and arm adjustment, at higher prices. The B100 Pro covers the basics for less.
