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 am thoroughly pleased with my purchase in every aspect. The product I acquired is of exceptional quality, exhibiting versatility and reliability, thereby significantly improving my overall user experience. I would wholeheartedly recommend it to individuals seeking such qualities in a product.

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!
