I'll be doing the same over the next few days to put her up for the winter
We're planning on our Alaska trip starting in May but getting ready to hibernate for a while in a land of snow and ice.
As for the table; when our grand-daughter gets old enough I might cut the width of the table down, use the cut-offs for braces on the seat bottoms and make a cushion to fit. It'll only make for a short bed but should work for a kid.
