This is a nice feeling solid chair. Easy to build. Parts were labeled and separated for easy setup (pretty neat thinking actually). While it says it's ergonomic it doesn't really offer any lumbar support for the lower back. I have placed a gel-pillow on it to help with the support. Very sturdy though and I've enjoyed it all week. Hopefully for years to come. I would recommend this chair (unless you need a lot of lumbar support).
The amount of assembly required would challenge an engineer. Would not recommend this unless you have a lot of free time on your hands and don't really need the chair soon
