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.
I don’t think you could fit them over glasses. Luckily I’m nearsighted so it doesn’t really matter for my use case
I’m very nearsighted. I wouldn’t be able to read that way bevause it would be too far away.
