Along with all the parts, Vertagear include an additional box which contains the instructions manual, gaslift mechanism and five plastic wheels. The gaslift is weighty and sturdy and the wheels are also constructed of good-quality materials.
The lower section of SL4000 consists of a single piece of steel to form the feet for the chair. This piece of metal is well-made, substantial and has a matt finish as opposed to any gloss.
Each of the wheels clip directly into the ends without the need for any screws or tools.
Independent of the actual chair, there are two similar sized cushions included with the SL4000. Both cushions utilise the same materials and finish as those found on key parts of the chair – carbon pattern and matt PVC leather. Both also feature double stitching and elastic straps to attach to the chair.
One of the cushions is used as lumbar support for your back and the other is a headrest to supply extra support for the back of the head. Both items are of course optional and can be used as desired.
