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.
Do you take notes by typing or by hand with a stylus. Or do you use one of those Samsung automated OCR handwriting? I want to try a tablet for my workflow but I hate typing on touch screens. It even infuriates me on my phone.
