A small office swivel chair can hide a big risk. How to avoid these risks when choosing an office chair? As an office furniture company with 15 years of manufacturing experience, Yonso always insists on producing high-quality chairs that meet safety and health standards. Here are some vital chair selection criteria for your reference when purchasing office chairs.
1 Check whether the gas lift has safety certification
The quality of the gas lift is one of the important elements that determine the safety factor of the office chair. It is reported that an inferior gas lift mostly causes the cause of the explosion of the office swivel chair. Therefore, when choosing a swivel chair, you must first check whether the gas lift has passed the test of SGS/BIFMA/TUV and other authoritative organizations. Currently, the gas lift used by KC and the most well-known office chair brands is mainly gas lifts that have passed multiple safety certifications. In addition to printing the manufacturer’s trademark on the rod body, the gas lift will also be printed with national certification marks. With the certification qualification, we can identify the pros and cons of gas lifts.
2 Check whether the seat base is installed with explosion-proof steel plates
In order to ensure safety, regular office chair manufacturers will install an explosion-proof steel plate, which is not less than 2 mm at the connection between the gas lift and the seat cushion. This steel plate prevents the gas lift from exploding during use, breaking through the seat cushion, and causing harm to the human body, so as prevent it before it happens.
3 Check the chair base, chair wheels, and fabric materials, and choose the best according to actual needs
3.1 Chair base
It is the key point to the weight capacity of the chair. When choosing the chair, you need to see clearly its material, weight capacity, and inspection standards. The materials of the chair base include PP, PE, nylon, steel, aluminum alloy, etc. Sorted by strength, aluminum alloy > steel > nylon > PE > PP. Nylon and aluminum alloy are commonly used in the chair base. And nylon is the most cost-effective and with a high usage rate on the market. Qualified nylon chair bases have good toughness, tensile and compressive resistance, and can reduce the damage of bumps at the same time. However, aluminum alloy is recommended for tall and heavy people.
3.2 Chair wheels
It is usually divided into three materials: PU, PA, and PP. PU chair wheels are soft and light, not easy to scratch the ground, suitable for hard ground (such as a wooden floor or ceramic tile). PA chair wheels, also known as nylon wheels, are rigid wheels with good toughness and high weight capacity and are suitable for use on soft ground (such as carpet). PP is a plastic chair wheel. The price is relatively cheap, but its performance is relatively poor compared to PU and PA. So PP chair wheels are not recommended. In short, the selection of chair wheels can follow the rules of hard wheels with soft ground and soft wheels with hard ground, abbreviated as “hard and soft”.
3.3 Cover
Office chairs on the market can be roughly divided into fabric chairs, mesh chairs, and leather chairs. Consumers can choose according to their preferences, but try to choose fabrics that are breathable, wear-resistant, and non-irritating. The breathable fabric will increase the comfort of the seat, especially in hot summer. Wear resistance can increase the service life of the seat. Non-irritating is based on the consideration of non-toxic safety.
Require merchants to produce relevant test reports
Among the quality problems of office chairs, in addition to the most embarrassing problems such as the explosion of the gas lift and the damage of the chair base and chair wheels, there are also problems such as excessive formaldehyde and poor flame retardant. As a consumer, some problems are difficult to distinguish with the naked eye. So how to check whether the selected office chair has such safety hazards? The best way is to ask the merchant to show the relevant test report when purchasing.
