The style of table you have selected will directly impact on which chairs will work. For example, you'll often find that circular tables can accommodate far wider seats and even high backs will work well, wheres more angular designs often require compact chairs, as they'll have legs to contend with.
For a more interesting and unusual style of dining furniture, rustic bench seating should absolutely be considered, as it offers a beautifully unique aesthetic. Easy to combine with regular chairs, for a little diversity, bench seats are ideal for busy family homes, where the evening meal is considered to be a cherished moment of reflection and interaction. Children always enjoy a more fun style of furniture and with a bench seat, there's always room for one more guest.
