Chairs (and stools and ottomans) are so essential to good living that we often take them for granted. Treat them like the thrones you deserve, and while you’re at it, think about which ones in your place could use an upgrade or a complementary friend. For lounging, perching, working, dining, conversing, thinking, and reading, nothing beats a perfect chair. When lying down or standing won’t do, find middle ground in seating that’s sublime.
