LapGear Compact Lap Desk - Pack of 12 - Charcoal

This was cheap, is extremely light, was already assembled and works perfectly to raise your smaller laptop just slightly off your legs which is exactly what I wanted.

Light weight and non-slip surface. Perfect for raising your laptop slightly or keeping the heat from the laptop off your legs. If you are looking to raise the height of your laptop significantly, for example to be at a better height for Zoom meetings, this product will not do that. It could also work well as a writing surface, if you like to use paper and pencil.
