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.
Here you go.
People complain in the comments about it falling off and breaking the mirror. I can attest the base does pop off after maybe a month or two of daily use. If you remove the mirror when you aren’t using it and re-suction every once in a while it’s really not an issue. It’s a bit unrealistic to be asking for an infinite suction cup. Materials admittedly feel cheap but it’s only $20. Just don’t put the base above anything it would damage if it pops off on you.
