There's something wonderfully warm about nontraditional bedside tables to personalize a bedroom. In this case, the "nontraditional" isn't a table at all, but serves the same purpose: the bedside chair. Other than the mantelpiece-turned-headboard, these bedside chairs were the first thing we noticed about this bedroom. More examples below:
Domino featured this bistro chair as a bedside table (via This Is Glamorous)
Martha Stewart Living example (via Contented Me)
Bedroom via Habitually Chic: Not shown as a bedside table, but we'd happily scoot this great chair on over and make it one.
