Started as a Kickstarter project in early 2015, Bookniture raised almost $450,000 to make their small-space design a reality. The concept is simple: When not in use, each "book" folds up, and is easy to store on a shelf. Having friends over? Open it up to create a stool or side table! Available on Bookniture.com; $86.

Here, it can serve at a moment's notice as additional, surprisingly comfortable seating. Then, when not in use, the lightweight, collapsible stool tucks into a corner or closet. Available on Etsy; $69.
