Rocking chairs are beautiful and universally loved, but how often do we actually use them? Honestly. We sit in them on a rare whim, and watch how they gather dust for the rest of their existence. But what if we could turn any chair into a rocking one when we need it and back when we don’t? This is the idea behind the Skis de Chaise from French designer Marie Thurnauer. These ‘skis’ can be applied to any four-legged chair. The wooden attachments snap into place, transforming your sitting into rocking! Made from wood, the Skis de Chaise has a slightly vintage feel to it, which adds one more complement to your existing furniture.
