Safety standards for office chairs
To ensure the safety of the lift chair, first of all, it depends on whether the three main parts of the air pressure rod, the chassis and the chair leg are of good quality, and secondly, consider the advantages and disadvantages of the seat fabric.
01. Lifting air pressure rod
The ergonomic chair lifts the seat by controlling the air pressure inside the air rod. It is the only component linking the seat and the chassis. It can be said that it is the core of the entire seat. The lift chair will threaten personal safety mainly because of the inside of the air pressure rod. The nitrogen is not pure, or the thickness of the pipe wall is not up to standard. To ensure the safety of the seat, the nitrogen purity inside the gas pressure rod must reach more than 90%, and the thickness of the pipe wall should be controlled between 38-45cm.
When choosing an air pressure rod, you must look for it: those with authoritative certifications such as SGS, BIFMA, TUV, etc., the strength is divided into 4 grades. Mark C on the air pressure rod as lass1/2/3/4. The higher the grade, the heavier the air pressure rod, of course. Security is also better.
02. Seat chassis
Under normal circumstances, a high-strength chassis can buffer damage, but now: Ivyco and other well-known office furniture brands will also add explosion-proof steel plates to the chassis to provide an insurance for the safety of the buttocks to avoid direct damage to the body by the air pressure rod, even in the event of an accident It will only be injured by bombs, which increases the safety factor.
03. Seat legs
Lift chairs are usually five-star chair legs, because the stability is the best, which can prevent the seat from losing balance and causing a fall. The load-bearing capacity of the seat is determined by the material of the chair legs, mainly stainless steel, aluminum alloy, and nylon.
In terms of strength: aluminum alloy > stainless steel foot > nylon foot
In terms of price: nylon < stainless steel < gold-plated aluminum alloy < polished aluminum alloy
The strength of the chair legs is not only related to the material, but also to the structure. Many high-load-bearing lift chair legs will have reinforcing ribs inside, which will be safer for heavy people.
04. Seat fabric
The quality of seat fabrics will not only affect comfort, but also affect people's health. Because the price is relatively cheap, many unscrupulous businesses will use inferior fabrics, but inferior fabrics will generate more formaldehyde in the production process, and long-term use will endanger human health, so do not buy office chairs blindly cheap.
When choosing a lift office chair, you must see clearly. The above-mentioned places are inconspicuous, but they are the places that should be paid attention to. When choosing a liftable office chair (especially an unknown brand), you should first check the seat. Whether the quality of the air pressure rod, chassis and chair legs of the chair has passed the test, and then consider the comfort of the seat. If you can't choose, buy from well-known brands, you can avoid most of the safety problems caused by quality.
