Grey matters. This neutral is very popular for the home right now, so to find such a large choice when trying to choose a grey oak dining table set is to be expected. The colour is generally worked in through the choice of cushions or upholstery for the chairs, but occasionally with the finish of the table legs themselves, or even by applying a grey colour wash to the bare oak.
But just as important as the overall look of the table and chairs is the functionality. Pick a grey oak dining table set that suits the size of the room, and also the number of people you have requiring food. Dining benches are handy for seating more people than chairs would in the same space.
Find other dining room furniture to match the style of your grey oak dining table set, including sideboards and display cabinets. Grey can be matched with black and white, and also blue. Experiment with rugs, cushions and other accessories in these colours.
