First of all you need to consider the weather conditions of the area where the restaurant is located. It will ensure that you do not spend money on non durable furniture that will be destroyed by the weather. For example if the area has a lot of rain you should probably have movable furniture. This way you can easily fold it and move it inside. Some materials do not withstand a lot of heat, so choose them wisely. They should be long lasting and protected against rust and that the furniture is coated to give protection against weather conditions. Also the color of cloth for the cushions, if any, should be such that it does not fade a lot in the sun. Make sure that it is easy to clean as it will be exposed to dust and pollution all the time.

Another thing that is necessary to consider is the style. You need to maintain the same theme as the indoor furniture so that there is uniformity. Not every color compliments the outdoors; choose them cautiously so that they match the color schemes as well as the outdoors. Many customers will be attracted by the outdoor furniture and will base their decision on the elegance, colors and style of the furniture. So the overall ambiance needs to be appealing.

Keep in mind that customers sit outside to relax, so the element of comfort is important in making a choice. The height of the tables should match the chairs. If the chairs are too low as compared to the tables, your customers will not feel comfortable. Therefore, the individual pieces need to fit in well together. Also keep the size of the chairs in mind; they shouldn't be very small as not all your customers are petite.
