I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
Duuuude. That’s a creative idea I might also use if I need a lap desk again. And something easy for if you need to put a laptop on a soft surface, won’t be wobbly like the bean bag ones.
