It's an armchair, it's very comfortable. It is possible to sit for several hours. I sit for at least 8 hours a day, and at the end of the day I have no back pain;

The chair is highly adaptable for adapting to various body shapes, allowing for adjustments to both the armrests and the backrest.

I recently bought a Master chair for my desk, after my partner highly recommended it. I’d been using a dinner chair as my desk chair for over a year, which caused me some back pain. The Master chair has been incredible so far! The back support is amazing, and I love how easy it is to adjust the settings to change my posture throughout the day. I’m really hopeful it’ll help undo the damage from my old chair. Overall, I’m so happy with both the product and the fantastic customer service!
