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.
Wooden chairs, finished with a luxuriously quilted seat cushions, not only look pretty, they are fantastically comfortable as well, making them ideal for both formal and informal dining. The only aspect to be very careful about is the fabric covering the pads, as it will need to be washable. Nobody wants to deal with pesky pesto stains or tomato marks, long-term and family homes always seem to encounter spills.
