Office Chair Hollow-out Model
There are differences in the installation, functionality, and pricing of hollow-out model office chairs. Here is the specific information:

Installation Steps
The installation steps for hollow-out model office chairs vary slightly depending on the model, but the overall process is similar. Taking the W209 hollow-out model computer chair as an example, the first step is to place the five-star base with the bottom facing up, insert the five casters into the five-star base one by one, then insert the gas lift (the thicker end) into the five-star base and press gently, while paying attention to the 'L/R' markings on the bottom of the armrests. Next, align the armrests, seat pan, and backrest with the pre-drilled holes on the seat cushion and seat pan respectively, secure them with the appropriate number and size of screws, and tighten them with a wrench. Then, insert the gas lift into the circular hole of the seat pan and press gently, and finally install the headrest. When installing the W906 hollow-out model computer chair, first install the casters and gas lift as well, then align the armrests, seat pan, and backrest with the screw holes on the seat cushion and seat pan, secure them with screws and tighten them, and finally insert the gas lift into the circular hole of the seat pan to complete the installation.
Product Features
Both hollow-out model computer chairs offer a rich set of features. The headrest of the W209 supports up-and-down and rotational adjustments; the armrests can be raised and lowered, moved forward and backward, and moved left and right; the seat height can be adjusted by flipping the front lever, and it can recline at a large angle by flipping the rear lever. It is also equipped with a pull-out footrest for convenient afternoon naps. The armrests of the W906 can be adjusted up and down, forward and backward, and left and right, and can also rotate at a large angle; pulling the handle upwards adjusts the seat depth, pulling the handle outwards adjusts the reclining angle, pushing the handle inwards locks it, pulling the handle outwards and applying backward pressure on the backrest makes it return to the upright position. Turning the knob to the left loosens it, allowing light-weight users to recline easily, and turning it to the right tightens it, enabling heavy-weight users to recline comfortably. It also has a pull-out footrest.
