The invention relates to the technical field of seats, and particularly discloses a damping seat with a large-stroke lifting function. The top of a fixed bracket is fixed on a guide rail of a sliding adjusting part; the damping part comprises a movable plate fixed to the bottom end of the fixed support, an upper connecting sleeve with the bottom movably sleeved with a middle hole of the movable plate, a lower connecting sleeve located below the movable plate and a lower connecting sleeve with the top end and the bottom end corresponding to the upper connecting sleeve. The lifting adjusting part comprises a fixed outer pipe, a lifting inner pipe and an air pressure rod, the fixed outer pipe is sleeved with the lifting inner pipe in a sliding mode, the air pressure rod is located in the lifting inner pipe, and the bottom end of the air pressure rod is fixed to the inner wall of the fixed outer pipe. An adjusting rod used for unlocking the air pressure rod is arranged on a fixing plate fixed to the top end of the lifting inner pipe. The upper connecting sleeve and the lower connecting sleeve are nested on the periphery of the top of the lifting inner pipe; the problem that a vehicle-mounted seat is difficult to meet the requirements of a special vehicle for the lifting stroke and the lightweight damping aspect is solved.
