Engineered for both comfort and durability, this ergonomic office chair combines premium materials with thoughtful design to support you through long workdays. The backrest is crafted from a high-strength blend of 70% PP and 30% glass fiber, featuring a curved shape that naturally aligns with your spine, while the skin-friendly nylon mesh provides breathable, anti-slip support. Flip-up armrests made from the same durable composite material allow for flexible positioning and easy storage. Height adjustment is smooth and reliable thanks to a Class 3 gas lift, paired with a medium butterfly base featuring in-situ locking and an explosion-proof structure for enhanced stability. The sturdy nylon star base offers strong load-bearing capacity, rolling quietly on smooth 50MM black PA casters that protect your floors. For lasting comfort, the seat cushion is built with a 10-layer curved plywood core, high-density shaped foam, and elastic fabric that retains its support over time. Available in multiple color combinations with optional colored wheels, this chair delivers a tailored fit for any home office or professional workspace.
