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.
An ebike: I don’t even really drive anymore most of the time and it beats the hell out of being stuck in traffic. Getting around is fun again.
I always enjoyed cycling and still ride my MTB, but for getting around town quickly, ebikes are hard to beat.
