1 - Assembly. Very easy, it had all the necessary tools included, I assembled it without even looking at the instructions.
2 - Quality. Quite good and sturdy set without worrying joints, based on the simplicity of construction and materials. It comfortably withstands 10 kilograms without excessive tightening.
3 - Appearance. Nice color, generally beautiful, easily matches with dark furniture in a room.
Overall, it has many positives.

The only negative is for anyone who needs more surface area, so this solution will not serve them, and for those who have difficulty bending down to put on or take off the brakes from the wheels (yes, it has those too!)
