Be careful where you leave your computer while using this. The first thing I noticed after unpacking and starting to use it was that my laptop slides. I have a habit of leaving my computer on a tilting footstool, and today I got up in a hurry, forgetting to place the footstool in a level position, and my computer slid onto the floor. Luckily, it was a short fall and there was no damage, but . . . I'm going to have to find a solution for this, maybe non-slip shelf liner or velcro just on the cushion.
Otherwise, it's great! Featherweight, comfortable to use on your lap with NO transmission of heat, and the large opening between the top and bottom layers is perfect for tucking away the cords.
