I got two chairs for replacements for my grown kids computer chairs. It was easy to assemble. Take note on instructions: Don't completely tighten the screws on the arm rests before you add the back rest. There's two tabs that slide into slots. You won't be able to get the back part on with the screws tightened. Other than the fact I ignored that, I did figure it out in a few moments.The chair is comfortable to sit on. I agree with some of the other reviews that the arm rests are too low. All of the computer chairs I've had the arm rests keep you arms about parallel to the desk so typing and moving mouse is fluent. If I jack the chair up to maximum height, it's still a tad shy of this goal.I still gave it 5 stars simply for the fact it's a good chair at a good price and was easy to assemble. If you're a power computer user who sits at desk up to 8 hours at a time, you might want to think twice on this one.
