What is the difference between different grades of gas pressure rods? How to choose a lift chair with a limited budget?

Why does the lift chair automatically sink every time you sit on it after using it for half a year? But there is not much change in the weight after measuring it. What is the problem?
Mainly, there is a problem with the gas pressure rod of the chair.

How to choose a lift chair? Why are some lift chairs so expensive?

• First: gas pressure rod

Most of the gas pressure rods with a price of 100-200 are not certified or use first-level or second-level gas pressure rods. Generally, the price of regular gas pressure rods is dozens of dollars. If your lift chair does not even cost 200, then you should think carefully about whether to replace the chair.

If you have carefully looked at the gas pressure rod during assembly, the gas pressure rods produced by regular manufacturers will generally have steel stamps, the more common ones are SGS, TUV, and BIFMA, and the higher the grade marked on the gas pressure rod, the better the quality.

It is recommended to choose a grade 3 or 4 gas pressure rod, because the inner core wall is thick and it is safer to use.

Many lifting chairs are caused by the quality problems of the gas pressure rod, so we have to prevent it. The difference between gas pressure rods of different grades is not only in length and load-bearing capacity. You cannot choose a lifting chair based on weight or height unilaterally, and regularly check for dangers to avoid injury.

• Second: Chassis

The quality of the chassis between different price ranges is also very different. The above is a comparison of two chassis with high and low prices. We can feel a difference from the appearance. The texture design of the high price in the picture above has high technological content, while the design of the low price in the picture below is simple, and the corresponding safety is not so high.

• Third: Five-star feet

It is divided into three types: steel, nylon and aluminum alloy. Generally, the low-priced ones will use steel welded feet. Note that this is not aluminum alloy. Steel welded feet have limited load-bearing capacity and may rust after a long time of use, so the price will be relatively cheap.

Therefore, nylon five-star feet are more common. They are light to use and the floor wear is not so high. They are almost silent when moving.

A good lift chair can be used for 10-20 years or even longer, but the key is that the quality must be good and safe. Many times when I buy furniture, I will adhere to the concept of "you get what you pay for". If you convert it from the use time, you will find that buying a good quality chair will be better in terms of use experience than one or two hundred. At the same time, a good quality chair will cost only about 100 yuan per year for 10 years, while a poor quality chair will cost 200 yuan per year if it is replaced once a year. Safety risks must also be considered, but everyone's choice is different.
