This umbrella can not maintain any standing position without a  weighed base. This was not indicated in the information. After getting the umbrella we realized that . We then ordered the four piece water base that was recommended. With all four bases filled with water the umbrella still les forward 
.It is very unstable. I would not recommend this to anyone. The prior cantilever umbrella we had was great. No problems like this at all.Also the four weighted bases are very big and a tripping hazard.
