This table was designed to help up to four children sit in an ergonomically correct position while interacting with tablets. It also ensures expensive tablets are kept protected and safe. Cushioned supports protect the tablet from scratches and our tool-less mounting makes it easy to install and remove tablets. Four identical locks hold the tops closed and secure the tablet inside the table. The open section in the center of the table is 4-1/2"W x 40-1/2"L x 6-1/2"H and creates handy storage for headphones, stylus pens, and books. To provide comfortable viewing, the center of the screen is positioned 3" shorter than height of the table. The openings are designed for tablets sized 9.5" x 7.31".
