FAQ
The comfort test of upholstered chairs is a complex process involving multiple aspects of testing and evaluation. Here are some of the main testing methods:
1. Office chair testing instrument single-station seat back comprehensive test
Office chair testing instrument The single-station seat back comprehensive test is a commonly used method. It evaluates the load-bearing capacity, comfort and stability of the office chair by testing the comprehensive performance of the seat surface and backrest of the office chair1. This test includes a seat load-bearing capacity test and a backrest tipping stability test. The seat surface load-bearing capacity test simulates different load conditions, such as normal use, temporary overload, etc., to ensure that the seat surface will not crack or deform due to excessive weight. The backrest tipping stability test simulates normal use, reclining and other tipping situations to ensure that the backrest can safely support the user's body and will not endanger the user's safety due to tilting.
2. Pressure distribution measurement
Pressure distribution measurement is a common method of testing seat comfort. It evaluates the comfort and support performance of the chair by measuring the pressure distribution experienced by people on various parts of the chair. This method can intuitively reflect the pressure distribution of the human body on the seat, thereby helping designers and manufacturers optimize the design of the seat and improve the comfort of the seat.
3. Customized mattress comfort tester
In addition to the above-mentioned general testing methods, there are also some customized testing instruments, such as mattress comfort tester (simple version), which can provide instruments and equipment that meet corporate standards according to customer needs2. This type of tester is usually provided by professional testing companies and can be designed and manufactured according to the specific needs of customers to ensure that the test results can meet the actual needs of customers.
4. International standard testing
The International Organization for Standardization (ISO) has developed a series of standards to evaluate the comfort of upholstered furniture, such as ISO8191-1 Upholstered Furniture Seat Simmering Test and ISO8191-2 Upholstered Seat Open Flame Burning Test56. These test methods are primarily intended to evaluate the flame resistance of material combinations to ignition sources and small flames from smoldering cigarettes, rather than the fire resistance of finished products or portions of materials. They ensure the safety of upholstered furniture in practical use.
5. User experience research
In addition to the above physical testing methods, research on seat comfort also includes research on user experience. Research in this area usually uses subjective scale evaluation methods to evaluate the comfort of seats by asking users about their feelings and using questionnaires and scales to quantify users' subjective feelings. This method can better reflect the user's actual perception of seat comfort, but it is also affected by personal subjective feelings, so it needs to be combined with objective measurement data for comprehensive analysis.
The above is a detailed introduction to the comfort testing methods of upholstered chairs. It should be noted that the actual testing process may be more complex and requires
A variety of factors must be taken into consideration and may need to be adjusted based on specific usage scenarios and needs.
1 Introduction
Stability testing of upholstered chairs is very important, as it involves the safety of the chair during use. The main purpose of the stability test is to evaluate the stability of the chair under various conditions of use, including static and dynamic stability.

This method gives guidance on testing force values, number of cycles, etc., and is used to evaluate the performance of office work chairs, regardless of product materials, structural design, and production processes. The test results are only valid for the sample being tested. When the test results need to be used for other similar products, it is very important that the test sample can represent a certain production model.
2.3 Test methods for stability, strength and durability of child seats
There are also test methods for stability, strength and durability of child seats, which specify general test conditions, stability, strength and durability test methods for child seats8. This method is applicable to seats used by children aged 3 to 14 years old. If the child seat product has an adjustable function, the strength and durability must be implemented in accordance with the highest requirements, and the stability needs to be implemented once in the lowest and highest use ranges.
3. Testing precautions
When conducting stability testing of upholstered chairs, you need to pay attention to the following points:
Sample selection: The test piece should be a finished product. If the test piece is disassembly, the product should be assembled according to the product's assembly instructions; if the test piece can be assembled or combined in different ways, the test should be carried out in the least Assemble or combine test pieces in a manner that facilitates strength and durability testing.
Loading requirements: The loading speed should be slow enough so that the additional dynamic load is small enough and can be ignored. During the endurance test, the loading speed should be slow enough so that the test piece does not dynamically heat up and affect the results.
Test environment: All loading devices should be movable in the direction of force application and should be as close to the load-bearing surface as possible. In addition to the seat impact test, if necessary a piece of foam can be placed at the loading point to prevent sliding.
Comply with standards: Testing should be conducted according to relevant national or industry standards to ensure the accuracy and fairness of the test.
In daily work, the comfort of office chairs plays an important role in improving work efficiency and maintaining health. Here are some tips for improving the comfort of your office chair:
1. Adjust the height of the office chair
First, adjust the desk or workbench to the appropriate height according to the nature of the work. Different desk heights have different requirements for seat placement. Generally speaking, the ideal office chair height should be able to meet the 90-degree verticality between the thighs and calves, as well as the verticality of the spine and hips. This height not only relieves fatigue from sitting for long periods of time at work, but is also beneficial to health.
2. Use a lumbar pad
Many office chairs come with built-in lumbar cushions, and some high-end office chairs use more advanced intelligent technology to allow the lumbar cushion to be adjusted more humanely, such as height, left, and right adjustment functions. The height of the lumbar cushion should generally not be adjusted too high. It is mainly based on the ability to support the waist and facilitate the waist to borrow force. If the lumbar cushion is too high, it may be more likely to cause back pain.
3. Adjust the height of the armrest
The handrails should be positioned just enough to catch the upper arm, ensuring that the upper arm and spine are parallel. This not only improves comfort but also prevents muscle fatigue and pain caused by prolonged poor posture.
4. Adjust the angle of the chair back and cushions
The angle of the chair back should adapt to the curve of your spine and provide adequate support. If the back of your chair doesn't provide enough support, it can cause lower back pain. In addition, you can also consider using cushions to stretch your back in an arc, which can reduce back fatigue.
5. Use a wrist rest
A wrist rest is a good choice for people who work in front of a computer for long periods of time. It can help you maintain a correct wrist posture and reduce discomfort and fatigue caused by constant friction and contact between the wrist and the table.
6. Exercise regularly
Sitting for long periods of time can cause many problems in the body. Therefore, you can add some exercises to your daily routine and focus on leg and butt training to prevent health problems caused by sitting for long periods of time.
The above are some tips to improve the comfort of office chairs. Remember, everyone’s body is different, so it’s best to personalize your regimen based on your body’s needs.
Safety is an important factor that must be considered when designing an upholstered chair. Here are some key security factors:
1. Seat stability
The stability of the seat is the basis for ensuring safe use. Designers need to ensure that the seat remains stable in a variety of usage situations and does not tip over or collapse easily.
2. Seat comfort
Although comfort is not a safety factor, it is closely related to safety. An uncomfortable seat can lead to health problems by causing the user to remain in poor posture for long periods of time. For example, sitting too deep may cause fatigue in the waist muscles, and excessive inclination of the sitting surface may increase the burden on the muscles and ligaments, making it easy to fatigue.
3. Ergonomic design of the seat
Ergonomic design is the key to ensuring seat safety. Designers need to design seats according to the size and characteristics of the human body to ensure the safety and comfort of users during use. For example, the seating depth and width of the seat, the inclination of the sitting surface, the height of the chair back and armrests, etc. all need to be designed according to ergonomic principles.
4. Seat belt connecting piece design
When the seat is installed on the vehicle, the seat belt and the seat are fixed and retracted through connecting pieces. Qualified seat belt connecting pieces are smooth to ensure that the seat belt will not get stuck or be excessively worn. It will have a certain degree of toughness, with reasonable softness and hardness.
5. Seat cushioning and safety design
The seat and the base back cover are connected by a long steel shaft, which can be adjusted up and down by sliding in the shaft groove. This organ-like design can be seen in the shaft groove, the edge of the seat back, and the base slide.
That’s some information I found in the search results about safety factors considered in the design of upholstered chairs.
