My only gripe was the slightly outdated build instructions but the chair itself seems to be of good build quality, sturdy materials and comfortable. Very happy with my purchase after using it for a day. Hopefully I’ll still think the same in 6 months 🙂 ### ⭐⭐⭐⭐ yes *by M***G on 12 July 2024* great chair would recommend ample lumbar support great leg support to and great for long hours studying ### ⭐ Worst chair I’ve owned *by A***A on 11 April 2026* The most uncomfortable chair I’ve ever owned. No matter how I adjust it I never feel comfortable. The combination of the weird shape and the mesh material has literally cheese grated my spine caused damage to my skin which is still scarred after months of no longer using this torture device. Definitely would not recommend, especially the mesh, do not choose the mesh! Also no matter what I do, tighten, lubricate, add rubber washers etc it squeaks like you wouldn’t believe, you’d probably need ear defenders in an office full of these. ## Frequently Bought Together - SIHOO Ergonomic Office Chair with 4D Arms, 2-Way Lumbar Support - Adjustable Seat Depth - PU Headrest – Height-Adjustable Backrest – High-Back Computer Desk Chair (Black) - Logitech MX Master 3S - Wireless Performance Mouse with Ultra-Fast Scrolling, Ergonomic, 8K DPI, Glass Tracking, Silent Clicks, USB-C, Bluetooth, Windows, Linux, Chrome - Dark Gray - Xiaomi 30769 Motion Monitor Light bar, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/400106561-v1-m109](https://www.desertcart.hk/products/400106561-v1-m109) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-18*
