Quality Elements Of Office Chairs

Quality factor

A casters: ordinary casters, PU wheels (soft materials, suitable for wooden floors and machine rooms).

B Chair foot: bow frame (iron frame or wooden frame): the thickness of the iron frame directly affects the life of the chair. Surface treatment: spray paint, baking varnish (surface gloss, not easy to remove paint), electroplating (wood frame can not be electroplated), plating quality is good, it is not easy to rust. Usually the plating quality is good, look at the surface grinding, the surface and the welding place are polished, and the plating may be better. Moreover, electroplating products are not environmentally friendly, and developed countries have strictly controlled the number of electroplating treatment plants and the investment in environmental protection facilities.

C Air Rod: Also called the extension rod, used to adjust the height and rotation of the chair. The inside of the gas rod is filled with high pressure gas. Before the gas rod was invented, the height and rotation of the chair were adjusted by the mast, and it was eliminated because it was not user-friendly.

D Chassis: The part that holds up the seat, and the bottom is connected to the air rod. Many of the chair chassis with retail price below 160 yuan have no casing. After being used for a long time, it is easy to crack and shake. It is easy to have some iron plate thickness. The amount of caliper is only 1.7mm thick. It is usually 1.9mm thick. . The spring of the chassis is not long enough or heat treated. Heat treated new spring with a liver color instead of iron.

E Seat: It consists of wood, sponge and fabric. The quality of the board is usually not felt by consumers. Sponge: Recycled cotton, new cotton. 99% of the manufacturers use the two together. The thicker and harder, the higher the cost, the appropriate thickness and the appropriate hardness. Pressing the seat by hand, if you feel very soft, or do not need to press the seat to feel the end (wood), the quality is not good. There are also some unscrupulous manufacturers that use foam, sponges, pearls and other items that have not been reprocessed to act as sponges. Easy to deform, no use of resilience. Fabric: paralyzed, mesh, leather. Some of the existing chairs have no wooden boards and sponges, just a plastic frame pressed against the net. This type of chair is more breathable. Sitting on it won't be a fever soon, but more comfortable.

F Handrail: Thickness affects quality.

G Seat back seat connection (corner code): The seat and the back of the chair are separated, connected by steel pipe or steel plate. The steel pipe is best covered with steel pipe, only a small part has a sleeve. The steel plate is usually 6 mm or 8 mm thick. However, steel plates with a width of less than 6 cm must be 8 mm thick. Otherwise it is easy to bend.

H The material of the seat back and the seat: the quality evaluation method is similar, but the hardness is relatively soft. Too soft is also not good. The steel frame and the plastic frame chair are made of mesh and are breathable.

I Lumbar pillow: Some chairs have, some chairs do not, if necessary, look at the comfort of the chair.

J Headrest: Some chairs are available, some are not, and the necessity is to see the comfort of the chair. Adjustable function Some high-end computer chairs, such as seat, armrest, seat back, lumbar pillow, headrest can adjust the height. Low-grade chair with a relatively rough surface.
