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.
It's thin and sucks. Look at the sides, and the flap. Thin thin. It's the type of bag DoorDash has and there's a reason pizza shops have way better ones. I have one like it (out of my 2 bags). It's not worth it considering you'll probably have it for years. Don't save $10 just to be disappointed
Something like this, you can see the difference. Much thicker
