Don't get me wrong these panels are beautiful....BUT...They do not stay standing.  Even with expensive saddle style canvas sand bags on each leg...they fall over with every breeze and will BEND.  I contacted Wayfair, and truly disappointed...they tell you to send them back (pay for shipping, they are huge and heavy).  They took HOURS to assemble, and boxes are trashed.  Please tell me how we are just suppose to pack them up and return.  Information in description should detail how they should be placed in an isolated area where they won't get blown over.  The company of panels do provide bolts to fasten them to your concrete...but as described, the beauty of self-standing panels is the ease to remove them if you want.  We did not want to permanently connect them to our patio.  Again...hugely disappointed with Wayfair Customer Service and these panels.  Pretty to look at if you like to look at them laying down!
