Features of SIHOO A3 Domino Stereoscopic Lumbar luxury ergonomic mesh computer Gaming executive boss chair office Chair
1: Domino waist support system (adaptive lumbar pillow) can automatically adjust the angle, height, and bearing distance according to the user's needs (to accommodate more people for use), without the need for manual adjustment. Also, it won't pull clothes when sliding.
2: The backrest is designed with four adjustable gears that can be adjusted up and down, suitable for people of different heights (male and female users).
3: Scene-based armrest can better meet the problem of hand support when playing mobile games and handle games.
4: The 90°-100°-112° reclining design is designed according to normal office scenes, sitting and leaning against the office scene when tired, and resting scenes. The three angles can meet different body needs.
5: Considering that prolonged sitting can easily lead to poor blood circulation in the thigh area and cause diseases, we use a waterfall-type seat cushion. Meanwhile, the angle used in the Doro-C300 waterfall-type seat cushion is more conducive to the circulation of blood in the thigh area.
6: Other selling points include the mesh material used in the backrest and seat cushion, the S-shaped ergonomic design of the backrest, the movable seat cushion, the PU casters that are quieter and do not damage wooden floors, and the 4-level gas pressure bar for greater safety.
7: Short assembly time, quick after-sales service response time, and a 2-year warranty.
