Assembly was a breeze and took less than twenty minutes from unboxing to fully set up. The overall design is very comfortable, and the lumbar support does a fantastic job of keeping my lower back aligned through long workdays. My only drawback is that the seat cushion is quite firm right out of the box. I am hoping the padding softens up a bit with regular use, but otherwise, it is a solid, supportive chair. Plus it’s $120 less than on Eureka’s website.
