The instructions in the beginning are confusing as to what is right. We started out with it upside down which put the right on the left when we put it upright. We had to take it apart  and put it back together. But we found out before we got to the trays. Trays were difficult to align, but once it was achieved they were fine. They should note in the instructions there are segments sick out and line up with the next tray and snap together. The plastic warps so once you figure out how to push it out to be straight it will then line up to the groove it needs to be snapped in.
The plastic on the 2 front trays for holding brushes & pencils were broken in shipment. I would like replacements. 

Otherwise we like the concept. It raises up easily and is a solid, sturdy table. We are pleased overall. 
Only disappointment was the plastic trays being cracked & one has a piece chipped out.
