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.
My friend, let me introduce you do the MUCH better version that you don’t even have to plug in! The Temperfect Mug https://joeveo.com/ ~$50.00 and does not need anything plugged into it. Keeps my coffee at the right temp for HOURS. I am not joking even a little bit!
