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 have a single use for mine, and it’s grating frozen chunks of ginger for cooking.
No fucking about with the fibrous texture, no chopping, no bits. It’s just creates ultimate melt away ginger for stirfrys.
