We have not been able to use the cover because the umbrella is still in the box.  The stand we ordered to use with the umbrella arrived in a damaged and resealed box.  And when we opened the box, the hardware to put the umbrella stand together was missing.  When I called Wayfair, they informed me we would receive the part by March 31.  It is April 4, and we have not received it.  I completed another order and it now indicates April 18.  At this rate, we may not be able to use the umbrella until Winter.  Very disappointed with Wayfair.  Since our box was opened to provide the hardware to someone else, you think they would do the same for us.  Mail us the Hardware kit and hold off selling that umbrella until they receive a replacement Hardware Kit.  Very disappointed and not sure if I will order from them again
