Has this been tested? Sufficiently?

The next Olympics is going to be very eco-conscious, which is good, and the housing will be somewhat temporary, so they're going to use cardboard beds. 

Apparently they've thought this plan through.

Tokyo Olympics athletes are assured their cardboard beds won't collapse during SEX - so long as they limit themselves to two-in-a-bed

According to the article, they tested the beds by dropping weights on them.

But did they test them by dropping weights on them repeatedly?

I think more work needs to be done before the Games begin.

I'd dutifully volunteer.
