Description

An adjustable office chair suitable for patients with acute low back pain

technical field

The utility model relates to the technical field of office seats, in particular to an adjustable office seat suitable for patients with acute lumbago.

Background technique

Workers who often sit in the office, especially white-collar workers, spend nearly half of their time sitting in the office every day.
