Dog days at the office can sometimes get a little long, and thankless desk jobs — not to mention the desk chairs that come with them — can do a number on the spine.

Today's roundup of chiropractor-approved seats, however, keeps it fresh without bringing the pain. There's the ubiquitous Eames entry, of course, as well as a few new pieces in bright, bold colors and interesting finishes — just the ticket to brighten up an otherwise mundane eight-hour day while providing a little comfort to boot.
