### ⭐⭐⭐⭐⭐ Value for money

Product is amazing. Great comfort for the money. Installation was quick and seamless

### ⭐⭐⭐⭐ Comfortable, Supportive, and Worth It!
*by P***N on 29 October 2025*

I’ve been using **The Sleep Company Onyx Orthopedic Office Chair** for a few weeks, and it’s been a great upgrade. The **SmartGRID technology** and **adjustable lumbar support** make long work hours much more comfortable, and the **high backrest** gives good neck and shoulder support. The **upright seating position** takes a little getting used to, but once you adjust, it feels very supportive. The **seat cushion** may seem a bit flimsy at first, yet it’s comfortable even for long sittings. The **armrests could use a bit more cushioning**, though they’re still functional and well-placed. Also, the **free assembly service arranged by Amazon** was smooth and quick. Overall, a **great ergonomic chair** with minor improvements needed but excellent comfort, support, and value for the price!
