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 large dogs will tear up even the most ‘durable’ dog toys in a matter of minutes. Nylon? Kevlar? Doesn’t matter. But if I give them toys meant for really small dogs, they don’t tear them up at all. Go figure.
