[Ergonomic Design]The 29.5-inch thickened and widened backrest, along with 30D one-piece molded high-density memory latex headrest and lumbar support and top pocket spring seat cushion, follows ergonomics. It precisely supports head, neck, shoulders, back, waist, buttocks and legs. The 3.9-inch adjustable height, 90 - 135 degree adjustable backrest, retractable footrest and soft cushion-linked armrests enables the gaming chair to accommodate different heights and usage preferences. It can disperse 95% of body pressure and relieve long-sitting fatigue, applicable for work, gaming or rest.[No Collapse After Long Sitting]We've inserted the individually pocketed springs from mattresses into the gaming chair's seat cushion. Special-tuned, each spring flexibly adjusts based on force points, jointly enabling precise weight distribution. Wrapped with 45D high-quality, high-resilience sponge outside, it ensures no collapse during long sitting and buffers vibrations subtly. This guarantees no sagging during long sits, buffers vibrations subtly, and offers a cloud-like comfort. Their shape and support duration are 50% longer than traditional materials. The gaming chair cushion's surface air holes boost the spring system's load, cut noise, and enhance the overall sitting feel.[Comfortable and Sturdy]Our gaming chair features a skin-friendly soft PU leather surface with a thickness of 0.03 inch, resistant to friction, peeling and stains. With professional sewing, its breathability is 33 times that of traditional PU leather, enhancing comfort. The internal structure includes a sturdy one-piece alloy frame and heavy-duty anti-tilt shafts with great rigidity and toughness. The backrest, fixed by upgraded steel plates, can bear over 200 pounds of impact. Triangularly distributed fixing screws boost backrest stability.[Stable Without Noise]The BIFMA-certified gaming chair base has undergone thousands of static pressure tests and can withstand up to 2866 LBS, with Shore hardness 65 silent casters that form a 360-degree seamless swivel system without any jams and produce less than 45 decibels of noise for all kinds of scenarios. SGS certified level 3 gas lift, reinforced steel frame, and a maximum load capacity of 330 LBS ensure durability and reliability.Polyurethane(PU)
