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.

Component Material of Sihoo A3 Domino Stereoscopic Lumbar Luxury Ergonomic Mesh Computer Gaming Executive Boss Chair Office

Headrest

Made of PA and fiber materials, with adjustable lifting and rotating functions, it helps maintain a healthy and upright neck posture and relieve brain fatigue.

Backrest

The chair backrest features an innovative soft rubber support technology, forming a triangle-shaped flexible and elastic support that allows the backrest to move naturally with the body and posture. It provides optimal support for every area of the back, with 4-level height adjustment, S-shaped backrest frame that fits the curve of the spine, and comprehensive support for the back, making sitting and reclining more comfortable.

Lumbar Support

Made of PA and fiber materials, it is self-adjustable and provides strong and supportive force to the waist, promoting a healthy and upright back posture.

Mechanism

The chair has a self-weight-bearing base that allows adjustable height, adjustable front and back seat movement, large-angle reclining, and is suitable for both office and leisure use.

Seat Cushion

The seat cushion is designed to relieve pressure, with a curved surface that provides the most comfortable support whether you are leaning back or forward. It relieves pressure on the back of the thighs and entire buttocks. The "waterfall" shaped side of the seat effectively reduces pressure on the lower side of the thighs, maintaining smooth blood circulation.

Mesh

The headrest, backrest, and seat cushion are all made of domestically produced high-quality mesh material that is breathable, oil-proof, and dirt-resistant, more sturdy, pressure-resistant, tear-resistant, and durable.

Armrest

The new 5D armrest is super soft and thick, with adjustable height up to 60mm and adjustable inward rotation of 60 degrees/outward rotation of 15 degrees. The PU armrest surface can be rotated inward/outward and adjusted forward/backward up to 50mm. The armrest can be rotated upward by 35 degrees, providing customers with a unique gaming experience.

Wheels

The chair has electroplated PU wheels that glide smoothly and have a rounded edge to protect the floor and prevent scratches, and are flexible and silent.
