Chair is amazing. Ships in 3 boxes. There is a small instruction booklet that was hidden in the bottom of one of the boxes. They ask you to save the boxes in case you need to warranty something on your chair. Good idea if you have a warehouse to store them. 

Had a small issue getting the arms attached as the mounting holes don’t line up exactly perfect. There are no instructional videos for this model on the company website. 

Overall, love the chair. Super comfortable but I’m a big guy at 6’ 3”. My wife who is shorter at 5’ 5” has some issues with not being able to use the shoulder or neck massage function.
