Stool and Office Chair
There are significant differences in design and functionality between stools and office chairs. Office chairs have advantages in terms of comfort and functionality, and different models of office chairs have distinct features in terms of adjustability and installation methods.
From a basic definition perspective, a stool generally refers to a backless seating furniture with a relatively simple structure, primarily meeting basic sitting needs. In contrast, an office chair is usually a seating furniture with a backrest and armrests, designed with a greater emphasis on ergonomics to provide better support and comfort, making it suitable for long hours of office work.
In terms of functional characteristics, ergonomic office chairs have developed rapidly. Contemporary chairs have given rise to the category of ergonomic chairs, which incorporate smart chips and highly sensitive sensors to enable dynamic lumbar support that automatically adjusts the support force according to the user's sitting posture, effectively reducing lumbar pressure. Some high-end office chairs also integrate immersive audio systems and health monitoring functions, such as monitoring health data like heart rate and breathing through built-in sensors and providing relaxing music or prompts through the audio system to enhance the user experience. In 2025, the industry introduced three-zone adaptive lumbar support technology and highly elastic anti-aging mesh materials, further improving the comfort and durability of office chairs.
Taking the Jingdong Jingzao Z5Pro as an example, its lumbar support can be adjusted up and down as well as forward and backward, and the backrest can be adjusted up and down,ๅธฆๅจ (this Chinese character seems out of place here, perhaps it was a typo and should be removed) the lumbar support to adjust together. It can be fixed with a bottom knob and the support force can be adjusted to meet the needs of different heights and sitting postures. However, its initial angle is only 95 degrees, and the headrest cannot be adjusted forward and backward, which may have an impact on the user experience for some users.
In terms of installation methods, different models of office chairs also vary. For example, the 1012A office chair requires the installation of base casters and seat armrests, following video instructions to use screw C, install screw D on the inside, and place screw E with a washer to complete the installation. The 1011A office chair, on the other hand, requires inserting AL screws with a washer according to video instructions, fixing the seat armrests first and then tightening them, and using screws for fixation. These differences in installation steps require users to carefully read the instructions or watch installation videos during installation to ensure correct assembly.
