I have a Pottery Barn basic sofa & chair, built before 2013, which means that the slipcovers sold at Pottery Barn today no longer fit. I did some browsing and found Comfort Works in Melbourne, Australia. I emailed them and was told that they made slipcovers for the Basic Pottery furniture pre 2013. The price was 1/3+ less than Pottery Barn also! I emailed back and forth as well as ordering samples. Although I was very pleased with their sales/customer service reps, I was still nervous about the fit. I somewhat hesitantly ordered! Wow!, when they arrived I was so pleased with quality and fit! I must admit that the cushions of these well used Basic pieces are not as firm as they were (and no slipcover will renew that) but I will now get several more years use from these pieces, allowing me to spend monies on re-furnishing another room! I highly recommend Comfort Works!
