The Taby Tray was developed by parents of little children who wanted to make traveling fun for the whole family. This car seat tray is an entertainment center for the kids that attaches perfectly to car seats (and strollers too), giving kids the ability to play and eat while on the go. Imagine the long road trips, pushing the stroller through the mall, or being stuck in traffic... Having the Taby Tray makes moments like these fun for the kids, as its the perfect car seat tray entertainment center. The Taby Tray holds snacks, drinks, books, toys, crayons, etc. easily. It contains a cupbottle holder to help prevent spills. Washes easily with soap and water, and fits most child restraints and strollers. Excellent lap tray. No assembly required. The TABY Tray works on the following: Car seats with armrests, Car seats with an over head shield that is lowered in front of the child after the child is strapped in the car seat, Booster seats with armrests, Booster seats with no armrests.
