People who live in tiny houses end up devising table solutions that fit their circumstances and lives, and that somehow work in the limited space available in their homes. Some use one surface to serve multiple purposes; for example, a counter or desk that is also used as a table. I've seen many creative examples of folding tables--tables that fold out of the way when not in use (and are usually permanently installed).
I mentioned in an earlier post that I have discovered that, unlike when I shared living space, I do not have a daily need for a table now that I live alone. When alone, I do not eat at a table. I never use a desk at home as a desk. (I never did, not even when I was in college.) I use a laptop computer in my lap, and I use a drafting board in my lap. Thinking honestly about how I live these days, I reached the conclusion that I only need a table when I have company over to dinner and for the occasional project (like when I set up my sewing machine, for example). Therefore, I will use a 28" diameter table that, when not in use, is folded away in a small closet with some folding chairs. When I need a larger table to seat more people, I will add a folding 48" table extender to the top of the table.
(These are not the chairs I will use in my JayBee, but I thought they added perspective to the table's size.)
One additional benefit to using a folding table is that I will be able to easily set the table up outside when I want to serve dinner on my deck.
