Negative Positive
Title: wobbly
Review: good quality. the concept is great, however the tray bounces all over due to the design of a round swivel under the rectangular piece (which is too lightweight to maintain a level position). i have a plain tray (no swivel) for 1 deck, that i put the felt chair glide pieces on and it works better than this one (my opinion).
