This parasol umbrella is of excellent quality, lasts for a long time and comes with a 2-year warranty. The sturdy rib of the umbrella can sufficiently support the canopy. The beach umbrella is made of UV protective and anti-fade polyester which is nice to block out the harmful UV rays of the sun. This umbrella can be mounted on your existing stand or in the middle of tables if holes available. The umbrella can be adjusted to any direction with tilt function, which provides you with optimum protection against the sun. The vent on the top is designed to promote airflow, allowing the bench umbrella to combat high winds to keep more stable.
