Supportive Innerspring This gaming chair uses pocket spring cushion to make it ergonomic. The special reinforcement structure is adopted to endow the spring structure with excellent durability, so that the spring will not be tilted and deformed. Each spring body operates independently, expands and contracts point-like, and supports independently. The force between the springs is evenly distributed and responds to every movement of the body independently, so there is no need to worry about the pressure on the waist when sitting for a long time. Rhombus Suture Design The parts of the high back and seat cushion are sewn with long needles, stitched according to different patterns, so as to divide them into uniform diamond patterns. It makes the overall shape of the game chair more three-dimensional and full, with a fashionable and advanced texture.

Wheel Wheels made of soft PU material, move smoothly and without noise. It has a long lifespan because we have tested it for durability. Gas Cylinder With the industry's top grade 4 hydraulic pressure, even if the computher chair is lifted and lowered more than a thousand times, it will not be damaged.
