I regret to say that this is the worst chair I have ever used for work. Despite its decent appearance, the chair has several major flaws. Firstly, it feels like you're constantly tilting slightly to one side, which is both uncomfortable and unsettling. The back support is ineffective; I use a pillow just to make it somewhat functional. Additionally, the leg extension feature is poorly designed. When using it, I feel like I might fall backward at any moment. Overall, I am extremely dissatisfied with this chair and would not recommend it to anyone.
