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!

But now I'm realizing it: This chair wants to make me healthy! Lumbar cushions, neck cushions... Things you don't find on a normal office chair! Comfortable, supportive... unusual! My body has always been more "hunchback at the top, hollow back at the bottom"! Now the chair is trying to correct both!
