Height and Angle Adjustable Headrest

The chair features a headrest that is both height and angle adjustable. This headrest can be rotated up and down, allowing for flexible adjustments to fit the curvature of your cervical vertebrae and provide relief from cervical spine pressure.

SIHOO M57 Integrated S-Shaped Backrest

The chair's backrest is designed with an integrated stable back frame that offers scientific support for your back. The S-shaped backrest, combined with the polyester mesh material, provides robust support and conforms to the natural curve of your waist, promoting better spinal health.

Effectively Adjustable Lumbar Support

The chair includes a 2D lumbar support feature, which allows for free movement both vertically and horizontally. This adjustability enables you to customize the lumbar support to suit your specific needs, providing strong and tailored support for your lower back.

SIHOO M57 3D PU Armrests

The chair's armrests are equipped with thick and soft padding for enhanced comfort. They can be adjusted in multiple ways, including vertical movement, horizontal movement, and swiveling up to 34°. This versatility allows you to position your arms comfortably in various ways while working.

SIHOO M57 Breathable Mesh Seat Cushion

The chair's high-density mesh seat cushion offers a comfortable and soft seating experience. The cushion follows a waterfall design that conforms to the natural curve of your buttocks. Additionally, the front section of the cushion contains high-elasticity shaping cotton, which effectively reduces pressure on your buttocks and thighs, relieving any sense of discomfort.

110°-130° Three-Position Tilt Back Angle

The chair provides multiple reclining angles to accommodate various preferences and needs. You can adjust the backrest to a 110° curve, which is more ergonomic than the standard 90°, providing better support for your waist. For different scenarios, you can further recline to 116° for a relaxed sitting position or to a fully reclined 130° position for a comfortable and rejuvenating rest.
