Outdoor Patio Umbrellas Market umbrellas for outside furniture provide shade and color to an outdoor area such as a deck or patio. Large patio umbrellas look great in any backyard when placed in the center of a patio table or standing alone over a bistro set or lounge chairs by the pool. Outdoor umbrellas are necessary additions to patio furniture during the warm months of the summer to provide protections from the sun's rays and heat. Patio table umbrellas and outdoor patio umbrellas are also great to protect little ones from the sun when they play outside. Deck furniture with patio furniture umbrellas also have covers to protect them during times not in use.
