This tray tray table is for car seat cupholders so that your little ones can snack/color on the go. The cup is designed to accept a standard skateboard bearing seating a tray with a 8mm bolt of at least 20mm in length. The bolt sits nicely in the cupholder, and slots into the cup body which is placed in the car-seat's cupholder.
The bearing allows the tray to spin so that it make getting your child in and out of the car quicker.
The tray has a cup, lip around the edge so that whatever is on the table does not slide around, and slots for crayons or markers.
