[0002] E-sports chair: An e-sports seat, simply referred to as an e-sports chair, where e-sports is an activity that reaches the competitive level in video game competitions. E-sports is an intellectual confrontation sport between people using electronic devices as sports equipment.

[0003] It mainly consists of a skeleton, a bottom plate, a gas lift rod, and a five-claw base. These four components form the frame of the e-sports chair, which is also the key to its quality. The skeleton includes a backrest and a seat. Since the people using the e-sports chair sit for a long time, it is required that the backrest of the e-sports chair has good breathability. In the disclosed patent 2022218329441, weft knitting yarns and warp knitting yarns are woven in the outer frame. The weft knitting yarns play a role in supporting the warp knitting yarns. At the same time, the weft knitting yarns can be closely attached to the user's back. The rectangular ventilation holes formed by the weft knitting yarns and the outer frame can improve the ventilation effect. And a wear-resistant composite layer is provided on the outside of the spun cotton core silk, which can make its hair filaments flat, reduce the friction force with the user's back, and reduce the wear on the clothes.

[0004] Although placing the ventilation structure on the front of the backrest is convenient for ventilation and reduces the wear on the clothes, since the ventilation structure woven by wires lacks the supporting force for the waist, e-sports players are prone to waist fatigue and damage to the lumbar spine after sitting for a long time.
