We bought two of these as kitchen chairs.  They are super comfortable, easy to clean, adjustable and tilt back for even more comfort.  They roll just fine on our vinyl plank floor.  Some of the reviews said the dark grey had a blue hue to it.  This was a bonus as we paired the chairs with a custom navy quartz table top with chrome legs.  The combination could not look better.  Where else but Wayfair can an average person renovating and decorating conceive of a  final product and then find exactly what is needed to make that dream a reality.  I love the endless choices.
