Abstract

The invention relates to an ergonomic chair, which comprises a chair back and a chair seat. The front surface of the middle lower portion of the chair back is protruded forwards, the protruded portion extends along a horizontal direction, recess structures are symmetrically arranged nearby a center line of the protruded portion left and right, so that a curve surface corresponding to the spinal column of a human body is formed, the chair back and the chair seat are integrally formed, or the chair back is used as an independent component connected to the rear of the chair seat, and supporting legs for supporting the chair seat are fixedly disposed on the lower portion of the chair seat. The ergonomic chair can effectively support the lumbar vertebra of the human body, and is favorable for relieving fatigue.

Description

Technical field [0001] The invention relates to a chair, in particular to an ergonomic chair that can support the lumbar spine of a person.
