I bought this same umbrella from Wayfair 6 summers ago.  It still looks great and yet I have never stored it during the harsh winters we can get.  And , an awesome fact:  while my neighbors umbrellas were flying across yards and my next door neighbor’s trampoline blew up against my deck, my umbrella did *not* move!  This was during a tornado warning and a very severe thunderstorm.  And, it has continued to stand its ground during many more severe weather outbreaks.  I use the recommended base for it and just fill each piece with water.  I live in Ohio and the summer sun can be grueling and this gives so much shade!
