Patio umbrellas bring a quaint café atmosphere to your backyard patio or gazebo. Most patio umbrellas are constructed of a wooden or aluminum skeleton frame. Before purchasing an umbrella make sure it's easy to open, close and tilt side to side. If your existing patio table has an umbrella hole, you should be able to insert almost any umbrella. However you may need to purchase an umbrella stand or base separately as an anchor so that your umbrella doesn't blow over or away in strong winds. Umbrellas are available in every color and fabric imaginable. Choose a fabric that's water resistant and provides UV protection. A complete umbrella with stand ranges from $200 to $400 online.
