Office Chair Accessories Knowledge
Office chair accessories knowledge covers the following key components and their characteristics:
1. Casters
Casters come in two types: regular casters and PU casters. PU casters are made of soft materials and are suitable for use on wooden floors or in computer rooms where the floor is prone to scratches, effectively preventing floor damage; regular casters are suitable for general floors. Casters need to be paired with a five-star base to ensure 360-degree rotation flexibility.
2. Chair Base
The five-star base is the universal design for chair bases, offering strong load-bearing capacity and high safety. It can be equipped with either pneumatic or screw lifting mechanisms. The thickness of the iron frame directly affects the service life, and surface treatment processes include polishing, painting, baking paint, and electroplating, with electroplated chair bases having superior rust resistance when the process quality is good.
3. Gas Lift (Height Adjustment Rod)
The gas lift is used to adjust the chair's height and rotation function and is a core safety component. It is recommended to choose a gas lift of grade 4 or above and confirm that it has passed international safety certifications such as TUV and SGS to avoid explosion risks. Poor-quality gas lifts may cause the seat to suddenly drop due to loss of air pressure control.
4. Seat Plate
The seat plate connects the gas lift to the chair seat and supports the entire chair structure. A metal seat plate is more stable, and special attention should be paid to the smoothness of the tilt function. The design of the seat plate determines whether the chair can recline and the ease of adjustment, making it a core component that affects the user experience.
5. Chair Seat
The chair seat consists of a wooden board, foam, and fabric. The thickness and density of the foam directly affect comfort, and fabric options include linen, mesh, or leather. Theๆผๆฅๆฌพ (foam + mesh) combines breathability with support and is suitable for long-term use.
6. Armrests
The thickness of the armrests affects durability, with thicker designs being more resistant to wear. Functionally, 4D armrests support vertical adjustment to meet basic needs; 6D armrests offer additional forward, backward, left, right, and rotational adjustment functions, suitable for users with high operational precision requirements.
7. Backrest-Seat Connection (Corner Bracket)
The split-type backrest and chair seat are connected by steel pipes or steel plates. The thickness of the steel plate is usually 6mm or 8mm, and if the width is less than 6cm, an 8mm steel plate must be used to ensure load-bearing safety.
8. Backrest
The backrest uses a steel frame or plastic frame combined with mesh fabric. Mesh or cotton backrests offer better breathability than plastic backrests, and an aluminum frame structure provides more stable load-bearing capacity. Breathable design reduces stuffiness and enhances comfort during prolonged sitting.
9. Lumbar Pillow and Headrest
The lumbar pillow should have an adaptive adjustment function to fit the curve of the waist and reduce fatigue; the headrest is recommended to be 2D (height adjustment + rotation) or elastic, preferably equipped with memory foam filling to provide neck support.
10. Footrest and Wheels
The hidden telescopic footrest saves space and can be extended for use during lunch breaks; silent wheels are suitable for carpets or wooden floors, sliding smoothly without scratching the surface. The cooperation between the wheels and the five-star base should ensure smooth rotation without jamming.
