As recommended, definitely get a friend to help you build the chair, will probably half the amount of time it took me to build (1.25 hours) and also prevent you from accidentally building the chair upside down (like I did at first). But once I got it together it was all worth it, I’m going to immediately buy a second one for my room. 
The green color is definitely more teal in person, but the phone camera makes it look like a lighter shade than it really is.
