Sleeping 5th person at SSR

We are staying at SSR for the first time in December. We have been at moderates before but this is the first time in a DVC. We have five people staying in the room. I am wondering if the bench at the table will be large enough to fit a 10-year-old boy as a bed? Will that be feasible or do we need to think of something else for my son to sleep?

Thanks!
