Key Features

• 【𝐄𝐫𝐠𝐨𝐧𝐨𝐦𝐢𝐜 𝐃𝐞𝐬𝐢𝐠𝐧】The SIHOO ergonomic chair possesses all of the characteristics of an ergonomic design. The S-shaped backrest design mimics the human spine and fully supports the back. The adjustable headrest supports the neck, providing our health-conscious customers with long-term comfort and perfect support. The ergonomic office chair can easily tilt 110°–116°–126° and is height adjustable by 10 cm in order to help you find a comfortable position after long gaming sessions or when working from home.
• 【𝟑𝐃 𝐀𝐫𝐦𝐫𝐞𝐬𝐭】Unlike 2D armrests, 3D armrests can be raised and lowered in 5 positions, and the PU leather armrest surface can also be adjusted back and forth and rotated left and right as your sitting position changes, providing multi-angle support for your hands so that you can maintain a healthy, comfortable posture when gaming, streaming, working, or napping.
• 【𝐌𝐞𝐬𝐡 𝐌𝐚𝐭𝐞𝐫𝐢𝐚𝐥】The springy foam at the front end of the seat cushion and its curved design give you plenty of support while sitting. The seat and backrest are made of polyester mesh which is tough and breathable and provides support while keeping you cool and sweat-free on hot summer days.
• 【𝐇𝐢𝐠𝐡 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 & 𝐄𝐚𝐬𝐲 𝐀𝐬𝐬𝐞𝐦𝐛𝐥𝐲】Every part of this computer office chair has undergone strict safety and quality testing, including cushion impact tests, armrest fatigue tests, and chair foot static pressure tests.
