The Chatsworth house, the home of the Duke and Duchess of Devonshire, is over five centuries old. Home to the family's impressive art collection, it's a fitting place for an exhibition. But "Make Yourself Comfortable at Chatsworth" is not the type you'd expect. Open through October 2015, it brings modern seating—and some site-specific designs—to the home's historic interiors, making for an unusual juxtaposition of old and new.
