Adjustable Headrest

The 30cm wide headrest is equipped with a 9cm lift adjustment and a 45° angle adjustment, providing flexible support for users to relieve pressure on the cervical vertebrae.

Flexible Lifting Backrest

The backrest can be adjusted with a 6cm lift height, accommodating users with heights ranging from 155cm to 180cm. The backrest follows the natural curve of the human spine, delivering comprehensive back support for comfortable sitting and leaning.

Butterfly Bionic Lumbar Support

The lumbar support is designed in the shape of butterfly wings, perfectly matching the curvature of the human waist. Users can adjust the lumbar support up and down by 3.5cm, allowing for flexible and comfortable customization.

Fixed or Liftable Armrests

Users can choose between fixed or liftable armrests. Fixed armrests feature a crescent-shaped design made of high-quality materials with a delicate touch surface, providing arm support. Liftable armrests have a height adjustment of 10cm, enabling users to set the desired height to comfortably support their elbows.

W-Shaped Curved Seat Cushion

The W-shaped curved ergonomic seat cushion mimics the human hip line. It is constructed with a 1.96-inch thick virgin white cotton, offering a soft and elastic sitting experience. The cushion ensures even pressure distribution, preventing compression of the buttocks and legs, and is suitable for prolonged sitting.

135° Wide-Angle Tilt Back

The chair offers a recline angle range of 105° to 135°. A 105° angle is ideal for focused office work, enhancing efficiency during long periods of sitting. Adjusting the seat to 135° provides a comfortable resting position, reducing fatigue and conserving energy for more productive work.
