To start, this is a large gaming chair. The backrest and sitting area can easily accommodate big-boned users who weigh up to 135 kg (297.62 lb). The S300 is made out of breathable cold foam upholstery, and along with the fabric cover, this gaming chair offers one of the coziest sitting surfaces a gaming chair can offer. The fabric is a nice detail both to the touch and the chair's aesthetics. No matter the environmental conditions, the S300 will be fine, neither too cold or hot as is often the case with PU or leather covers. Sweat issues will most likely also not occur since fabric is breathable. We shall wait and see how easy it is to clean the white radiant stripes once they get dirty, though.
Sitting in the S300 is definitely an experience to remember. First of all, it's our first gaming chair with a fabric cover, and from now on, we will use it as a reference point for any other gaming chair featuring the same material. Secondly, the padding of the S300 has been distributed in a way that makes the whole sitting experience even better without the provided cushions. Personally, I have never before used a gaming chair or even an office chair (other than the Ergohuman and Secretlab Titan) without a lumbar-support cushion. While trying this chair out, a colleague of mine removed its lumbar-support cushion. Without even noticing it, I sat down only to realize how amazing it felt without the cushion. With this cushion removed, a user can utilize even more of the seat's sitting area while the pelvis and back areas are supported nicely by the padding of the backrest.
The armrests are 3D, which I didn't clue in on initially. One day , while in a rush, I grabbed the armrests right before taking a seat, and the armpads abruptly slid back. It was then that I realized that they could actually be moved to the front/back and inward/outward, which is great for the money spent as it gives you all the ergonomic features pricier chairs offer. Trying this chair out, all users did, however, find that the armpads would actually slide to the back or front a bit too easily. As such, you should be careful about grabbing the armpads to quickly take a seat since they can move forward, which might make you lose your balance.
A rocking mechanism is always welcome since it helps increase the blood flow to the body, improves the mood, and let's be honest, makes us feel as though we are fooling around while working or gaming! Well, the S300 has a rocking mechanism, but it works strangely. My colleagues and I weigh less than 80 kg (176.36 lb) each, and we could only rock back and forth under certain circumstances. The backrest must lean backwards quite a bit in order for the rocking mechanism to operate. Since there is a knob under the seat's base with which one can adjust the tilt's tension, we tried to loosen the tilt, but doing so didn't have the desired effect. We do not have a person that weighs more than 80 kg (176.36 lb) in our facilities to figure out whether the rocking mechanism would initiate more readily with more weight applied, and forcing two people to sit on the chair at the same time just wouldn't end well for the chair.
The caster wheels have a 50 mm diameter and are, as such, smaller than those most chairs use. However, they still only roll on demand and do not slide along on their own. Thus, these casters are of the hardest ones we have come across to date. With that said, making these roll on a carpet or an uneven surface won't be easy. Just for the record, I prefer caster wheels that are stable to those that move along too readily. The two-year warranty appears to be an honest one if you take two facts into consideration—the fabric used and the chair's low price tag.
