There are many factors to consider when choosing a porch swing. First, think about the comfort level because if you can't sit in it for long periods it defeats the purpose. Next consider the material, style, and color you're after. You should also be mindful of the finish, construction, and durability. Compare prices, attachment styles, and whether the porch swing can be used both indoors and/or outdoors. Also, consider if the swing chair needs to be hung or if it should be attached to a stand. Many are available both ways.
