Or find one someone else threw away.
Find one of these.
Not one of these. The previous is much more sturdier.
Go to one of these.
Find some of these in your favorite colors.

And finish having one of these. They make the perfect portable work tables, light saw horse, etc. They adjust to literally all heights. It is easy enough to lay a small piece of cardboard or plywood over the cover the grates. If you are lucky enough to find one with a decent cover yet, it makes a fine, none scratch surface to work off of. It's all been done before. Just trying to do my part to save our landfills from filling up. Thanks for looking.
