Easy to assemble. The lumbar cushion and neck pillow are filled with foam. Sitting is very comfortable, even for a long time (10 hours +).

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!

Very good chair! Especially good for the lower back
