Abstract: The disclosure relates to the field of seat design and manufacture, in particular to a lumbar support seat. The disclosure is achieved by the following technical solution: a lumbar support seat, comprising a lumbar support and a gas spring; the lumbar support closely fits with the back of human body through the expansion of the gas spring when the back is moved, to provide continuous and uniform uplift force. An object of the disclosure is to overcome defects of the prior art and provide a lumbar support seat. When the user moves on the seat back and forth, the lumbar support may move synchronously in contact with the back of the human body, to fit with the waist in real time, thereby increasing the supporting force in waist position of the human body.
