This iconic 1994 Herman Miller chair remains supremely relevant today. This entry-level model has fixed armrests, lumbar support and a legendary sense ofcomfort.

This Norwegian oddity demands you rethink sitting entirely. The saddle seat lets you perch, straddle, lean, or rise to standing height; constantly shifting position throughout the day.

The lumbar support slides precisely into place via side handles. Even with this discount, it's expensive, but if you value both aesthetics and ergonomics, the Gesture justifies its price.
