After what seems to be months and months of searching, we've settled on purchasing the York and Metro sofas, both in fabric. I've been able to look at about 4 York models in different furniture stores. None have had welting on upholstery. I've seen one Metro (in person) and one Metro (photos on this web site). The Metro models have both had welting at seams.

What are the pros and cons of having welts? Of not having welts?

Thanks.
