Find the right size to fit the space.
Think about sun protection when you make your purchase. Tightly woven fabric canopies are your best choices. Remember darker colors block out more rays than a lighter color will do.
Pick a sturdy base. Many of the newer Patio Umbrella's have a good amount of weight so getting a sturdy base is important. You will also need to factor in the weather as well. Certain area's of the country see more wind than others.
Read the warranty very closely. Many people do not even read it and that can be a huge mistake. Find out what is covered and what is not. This way you will know exactly where you stand with the product and the company.
