Pretty easy to assemble should take you under an hour easily. Chair overall is comfy and definitely is a good posture/support check for my back. I dock a star as I feel like the seat itself isn't as large as some of my past chairs. But asides from that good for a sitting up posture chair and good price for the discount.
1. When buying this blue mesh chair UN59458 they have two version that the mesh is different. The UN59458-CC (blue no vertical pattern) and UN59458-US(with blue vertical pattern). 2. Be careful if u pick Black color from the screen both back and seat are mesh! While blue has mesh on back and sponge type seat!
I checked on another few resources to get an inexpensive office chair (I spend 8-12 hrs in it a day). this one is comfortable (the seat) and flexible. I've had it a week or so with NO complaints. It has good lumbar support (adjustable). I do recommend it even at perhaps nearly full price.
