These trays were very high quality and perfect for our needs.  They were much nicer than we expected and very sturdy.  The snack tray and storage unit had to be assembled, but that was not very difficult.   Our only disappointment was that we had to wait for them until March.  It was supposed to be a Christmas present but they were sold out and not available until now!  They are very nice, so I can understand why they are so popular.
