When I am not wearing much.
Like now.
The laptop is so hot and I have a blanket under it, but that's making me hot too. I use pillows sometimes but they wobble.
I know I should have it on a table, but that is not comfy.
Maybe I could use those trays that have the cushion attached. The ones you're meant to eat your dinner off whilst watching tv!
I am aware I am answering my own question!!
