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 got my husband a manual coffee grinder when he got into coffee. I thought it was stupid to spend over 250€ on a stupid coffee grinder for a phase he would drop soon but oh well. I was wrong. Neither did he drop the phase nor was the grinder not worth it. It is a great grinder, I love it myself, and I am enjoying coffee so much more now. The snobs were indeed right all along.
