Although the Caliber R2 comes as a product that you must assemble, that shouldn’t worry you too much, as Cooler Master provides all of the hardware you need to be successful. A total of six steps are laid out in the included assembly guide, and they are for the most part very easy to follow. First up is attaching the backrest to the seatbase, which just requires using four bolts and associated washers and the included multi-tool.
The backrest sits in between two arms that stick up from the seatbase, and once you have the holes lined up, in go the bolts.
Next up is attaching the tilt mechanism and arms to the bottom of the seatbase, which is again accomplished with the multi-tool and bolts. The only real not here is that all of these parts are directional, so I had to make sure that the base was facing the right direction, or I would have tipped forward. The same goes for the arms, which can also be adjusted inward and outward to accommodate different widths.
With the bulk of the seat complete, two reclining mechanism covers are put into place to hide the inner workings of the chair recline feature. Two screws and caps and we are on to the next step. We did find their fit and finish to be a bit lacking, as they seemed a bit wobbly on both sides, being only held on by two plastic snap-in pegs each.
Flipping the five-pointed base over allows you to insert the included swivel wheels into their respective holes. These simply snap into place with a bit of a push. Flipping the base back over lets you slide the gas lift and lift cover into the central base hole.
The last step involves lifting the assembled seatbase and backrest and placing it onto the gas lift. This is all held together with pressure, so once the seat is in place, you are good to go.
If you choose to use the included lumbar and neck pillows, you can also attach them at this time – the neck pillow sliding down over the top of the headrest, while the lumbar pillow vertically snaps around the backrest.
