I love the Blue color and overall it is pretty comfortable when the backrest is in the slanted position. 
Assembly wasn't too bad, the included tools got the job done, Just be careful not to over-tighten any screws.
The only reasons I'm giving this 4 stars instead of 5 is because the backrest isn't too comfortable to sleep on in the bed position (too firm) and I wish that the armrests were a bit taller or had more padding.
