Brand Office Chair Specifications

Brand office chair specifications typically cover multiple aspects such as seat height, width, depth, backrest height, armrest height, weight capacity, materials, dimensions, and casters. Details are as follows:

Seat height is a core specification of office chairs and must be adjustable to accommodate users of different heights. The standard adjustment range is 400-550mm, achieved through a gas lift or mechanical structure, ensuring that users can keep their feet flat on the ground with knees bent at a natural 90° angle to avoid fatigue from prolonged sitting.

Seat width directly affects comfort and must provide sufficient space for the user's hips and thighs while seated. The standard width range is 450-550mm. If the seat is too narrow, it may cause a feeling of constriction; if too wide, it may affect lumbar support.

Seat depth should match the length of the user's thighs, ideally supporting more than two-thirds of the thigh area. The common depth range is 400-600mm. Insufficient depth will leave the thighs hanging, increasing pressure on the hips; excessive depth may compress the blood vessels and nerves behind the knees.

Backrest height should cover the user's back to the scapular region, providing effective support. The backrest height of ordinary office chairs is 700-1200mm, and high-end models may be equipped with adjustable headrests to further support the cervical spine and relieve neck stiffness caused by prolonged sitting.

Armrest height should be coordinated with the desk height to ensure that the arms hang naturally with elbows bent at 90°. The standard adjustment range is 200-300mm, and some models support forward, backward, left, and right angle adjustments to adapt to different office scenarios (such as typing or reading).

Weight capacity specifications reflect the structural strength of the chair. The weight capacity range for conventional models is 100kg-150kg, while high-end models use reinforced steel frames or high-density foam, with a weight capacity of over 200kg, suitable for larger users or those who need to move frequently.

Material specifications involve mesh breathability, foam density, and leather abrasion resistance. Mesh must pass breathability tests (such as the number of air holes per square centimeter) to prevent heat buildup; foam density is recommended to be 30-45kg/m³ for a balance of support and comfort; leather must meet abrasion resistance standards (such as a Martindale test result of ≥50,000 cycles) to extend service life.

Dimension specifications should fit the office space. The standard seat width is approximately 50cm, the backrest height is 100cm-120cm, and the overall height (including the headrest) should not exceed 130cm to avoid occupying excessive vertical space.

Caster specifications directly affect mobility and quietness. PU silent casters are commonly used, with a soft and abrasion-resistant surface that adapts to different floor types such as wooden floors and carpets, reducing sliding noise and floor scratches.
