The SPC Gear SX500 Onyx White is a highly comfortable computer chair with an attractive design. Predominantly white, it features silver and light grey accents, and is themed around the rare and precious white variety of the mineral onyx. “A visually-appealing computer station in a distinctive style is a reflection of its user, often a gamer. The computer chair should match the elegant and stylish character of a carefully selected setup”, said SX500 Onyx White designer Valeria Arlova. The materials were carefully selected and combined: the seat, backrest and two cushions attached to the chair were upholstered with a soft and breathable fabric, as well as high-quality PU leather. The bucket-chair profile, which features cushions that support the spine in key areas, and the highly adjustable 4D armrests ensure high levels of comfort not only while playing games, but also while working, studying or simply relaxing.


“White onyx gemstone is distinguished by a unique composition of colors: white, light gray and silver. Due to its peculiar character, I couldn't afford to make any compromises. Hence, even the supporting elements of the SX500 Onyx White, such as the base, large wheels, and even the actuator are also in colors reminiscent of the white onyx” — emphasizes Valeria Arlova. As a result: white, light gray and silver are intertwined, and tastefully blend in across the entire chair.


The choice of materials and where they are used is also not accidental: "In the central part of the seat and backrest — that is at the main point of contact with the body — I used an extremely soft, pleasant to the touch fabric that allows air to pass through, which is crucial when it comes to the comfortable character of the SX500. I chose the same material for the pillows”, adds Valeria. Located on the sides is a durable and easy-to-clean artificial leather (PU). The all-metal frame is embedded in cold-pressed foam, which not only provides even support, but also prevents deformation of the chair in individual places, and ensures comfort long into the future.

Comfortable support for your arms is extremely important when it comes to maintaining proper posture in front of the computer. That's why the SX500 Onyx White has been equipped with 4D armrests, which allow for four planes of adjustment: up/down, left/right, forward/backward and even the ability to rotate.


Another key feature of any ergonomic chair is adequate support for the lumbar spine and neck, which makes it easier to maintain correct posture at the computer. Included with every SX500 Onyx White chair are two pillows in a light grey colour, mounted with rubber straps. Both are filled with a durable and soft memory foam material. The neck pillow, as well as the central part of the lumbar pillow, are completely covered with a breathable fabric that is very pleasant to the touch.


In order to reach the highest levels of durability and comfort, both the seat and backrest are filled with cold-pressed foam ("molded foam"). Thanks to its elasticity, it provides adequate support for both the back and legs. Due to the filling formation technology used when building the chair, the foam retains its shape and plasticity, even after long periods of use.


Thanks to its TILT mechanism, the SX500 Onyx White is equipped with a rocking function. The force needed to tilt the chair back can be adjusted using the large knob under the seat. At any time, the user also has the option of completely blocking the rocking function.


A special mechanism located on the right side of the chair, connecting the seat with the backrest, allows for the adjustment of incline in a range from 90° (completely vertical position) to 170° (an almost horizontal position). Thanks to this function, you can adjust the backrest and essentially lie down in the chair and comfortably rest after intense gaming or equally intense work or study sessions.


The SX500 Onyx White uses a lift of the highest quality (up to 150 kg static lifting capacity) and allows for the adjustment of seat height to the user's individual height. It’s possible to set the height of the seat in a range of 40 mm — from 450 mm to 490 mm from the ground.


The light grey wheels have a diameter of 60 mm and are covered with a layer of nylon. This durable, and at the same time quite soft material, not only protects the floor from scratches, but also suppresses unwanted noise made when the chair is moved over exposed floors or tiles.


The steel frame, durable TILT mechanism, class 4 lift, and wide base are the core of the SX500 Onyx White chair structure. Each of these elements is characterized by extremely high levels of deformation resistance and support for the user's body. Due to this, we recommend the chair for people up to 120 kg, also taking into account the dynamics of sitting down (temporarily significantly increasing the pressure).
