It's weird to think there was an 18th-Century chair designed specifically for unmarried men, but then again, unmarried men in the 18th Century were themselves considered weird.
Presumably single men in the 1900s lived in garrets and other space-tight structures, hence we have this early example of space-saving furniture: A combination chair, step-stool and ironing board. You might be a single loser too short to reach the top shelf on your own, but that's no reason not to continue wearing crisp shirts that you press yourself.
If you're lucky you'll see one of these on eBay, and Woodworker's Woodshop sells plans for the chair if you want to build your own. We question their repetitive use of the heart motif, though; perhaps meant to be hopeful, it just comes off as sad.
