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.
For people that don’t have a work that pays for it, Nutritionix is it completely free? And is the database that MyFitnessPal uses. You get the same tracking, macros, and barcode scanning ability without the silly subscription or paid app.
