FAQ
Q: Is this chair suitable for tall users (e.g. over 190 cm)?
A: The chair is rated for recommended user height approximately 160-190 cm. Users significantly taller may still use it but should check the seat height and backrest clearance to ensure comfort.
Q: Can the armrests be adjusted to support a dual-monitor workstation setup?
A: Yes. The 3-direction lockable armrests allow forward-back and left-right adjustment as well as height adjustment, making it possible to align them with keyboard, mouse or console controller in dual-monitor setups.
Q: How does the mesh back compare to a padded leather back in terms of comfort and durability?
A: The breathable mesh back is designed to keep you cooler during extended use, especially in warmer environments. It also provides flexible support and conforms to your back shape while remaining durable thanks to its high-tensile construction.
Q: Does this chair require special maintenance?
A: Regular care involves vacuuming or lightly wiping the mesh to prevent dust build-up and avoiding direct sunlight for long periods. Tightening bolts annually and checking the gas lift for smooth action are also recommended for longevity.
