There was no instruction for the assembly but it was not difficult find how. Doing it was a little more co mplicated.  The pieces seemed to be so thight and didn't fit so well in each other.  I took me 2,5 hours of try and error but I achieved it finally.  And the color was not the same as the picture show.  The blue part is black.   I would hav prefer the blue... And also, it is foldable in half moon, Ithought it was the pillars and the bar who was... but except of all that stuff bugging me, IM satisfied for the use I will have of it.  It seems to be solid enough for a little person but Im not sure for a more than 150 lbs person...
