Factual Questions
1

If I wished to create an ottoman 2 feet square by 1 foot high, with the lid to be covered by 6 inches of foam padding, what thickness of plywood should I get to make the top and sides out of such that a 250 pound person could sit on top of the ottoman and not risk falling through?

(without adding center support, because the lid shall be liftable and the interior used for storage space.)

3/4" ought to be plenty. It workd great for flooring and would give a nice traction to any upholstery you want to add.

LV my husband, Craig the Carpenter, agrees that the 3/4" that MonkeyMensch recommended should be fine. Good luck and “happy building”.
