Installation: The installation steps for the 908/909 office chair are quite detailed. First, insert the five wheels into the five-pronged base, then install the gas lift. Next, use four M625mm screws to attach the backrest support, and then use three M820mm screws to connect the backrest to the seat pan. After that, insert the gas lift into the hole in the seat pan, use two M825mm screws to install the left and right armrests, use an M625mm screw to install the headrest, and finally, place two rubber bands on the footrest.

Usage: The Cmodels 909KT A72V office chair features multiple adjustment functions. The seat height can be adjusted using the flip-up lever on the right side to raise or lower the seat. For the multi-position tilt lock function, after adjusting to the desired position, flip the left lever to lock it, and flip it again to release the tilt lock. For tilt tension control, turning the bottom knob clockwise increases the tilt tension, and turning it counterclockwise decreases it.
