Plywood thickness for sleeping platform.

[Mules]

Here's my bed platform made from 3/4" birch plywood. I’m putting the pneumatic struts on this weekend.

I did not see it mentioned, but something you want to do is put a good exterior water sealant on the plywood, I like a penetrating sealant on all my wood. This will help to keep the plywood from warping and edges from cracking if it gets wet.
