What are the most important ergonomic chair specs for users under 5'3"?

Petite ergonomic chair specification at OfficeFurniture2go.com requires anthropometric confirmation: seat height minimum below 16\", seat depth maximum under 18\", lumbar lower range positioning, and armrest minimum height below standard. We maintain a curated petite-fit selection and confirm all three dimensions against user height. Petite users in standard chairs often compensate by sitting at the seat edge — losing all lumbar support. Call 1-800-460-0858.
