We bought two mats and both were cracked in shipping.  They were either shipped in a plastic bag or wrapped sheets of flimsy cardboard.  I know it's free shipping, but when it damages the product before it gets to you, it ruins the benefit of buying online.  Wayfair was great about refunding, but what we wanted was the product without it being damaged.

Pros: beautiful, functional
Cons: caution on shipping, may crack mat
