Due to the side post arrangement, offset patio umbrellas offer a lot of space underneath and appear very stylish and modern. They can rotate to change the angle of shade as the sun moves. This makes them an excellent choice for poolside decks, gardens and other outdoor areas. This larger-sized patio offset umbrella stretches a full 10 feet when opened, giving you complete shade all around - and because there's no pole in the middle, your shady spot will never be split in two.Please note that this patio umbrella does not come with a base. We highly recommend that you purchase a weighted outdoor umbrella base separately and fill it with water or sand for long, stable use.
