We received our chair and didn't open it till Christmas morning.  It was a gift for our son-in-law.  Imagine our surprise when we discovered it had no base!!  We called the next morning and customer service was outstanding!  They immediately sent us a new chair(base and all)  and we were allowed to keep the existing chair and are having a base mounted for it.  The chair is super comfortable and my son-in-law couldn't be happier.  I will be ordering again.  Thanks Wayfair!!!!
