Surface: The top of the lap desk is 17 inches wide and 11 inches deep, which is enough space for a 15.6-inch laptop. The surface is sturdy and flat to allow for adequate airflow and ventilation for your computer. Cushion: The Sidekick's microbead cushion holds its position on your lap or on a table, keeping your work surface steady. The cushion is soft and creates a comfortable workspace wherever you decide to sit. Features: The top surface of the desk has an integrated non-slip silicone bar to keep your devices in place, a built-in device ledge offering extra security, and a 6.5-inch phone slot that holds most smartphones horizontally. Compact & Portable: Due to the lightweight (1.14 lbs) and built-in carry handle design, the Sidekick Lap Desk is easy to pick up and take to class, the office, or on a trip. The surface is large enough for your computer but small enough to be used in tight spaces like plane seats. Versatile: This lap desk is also great for taking notes, writing in your journal, or reading a book. Watch a movie, shop online, or chat with friends in the most comfortable seat in the house. Your lap desk goes where you go and provides a flat surface for any project.
