Our extra was in the back closet on one side in the bedroom. But you definitely need the extra cushion. And, be very, very careful. The 'rails' that make up the lip for the table when it is down doesn't match up to the table edges for a darn, as the table edges are rounded. I made up a plywood plate that I put down on the rails first to make it more secure, stored it behind the dinette when not in use. The grandkids got dumped on the floor more than once when the table edge slid and fell.
