What is the standard seat pan depth for a conference chair?

Standard conference chair seat pan depth is 15–18 in., measured front-to-back. A seat pan that is too deep (over 18 in. for average users) puts pressure on the back of the knees, while too shallow (under 14 in.) provides insufficient thigh support. Some chairs offer a seat-depth adjustment of 1–2 in. for different user heights. OfficeFurniture2go.com provides seat depth specifications for all chairs — call 1-800-460-0858.
