I worked at a large family owned furniture store for a number of years and Rowe/Robin Bruce was one of the brands that we carried. IMO, I would say that Rowe is more of a mid line upholstery company with Robin Bruce being their “step up” product. To me the main difference was the style options and finishing choices in Robin Bruce. We considered them a good family friendly upholstery product and we did not get many issues from our customers on them. It’s been a few years since I worked with this line but I do recall them having a good basic warranty program (they used to have a lifetime warranty on their seat cores but I think it’s 5 years now) and they did fix the problems that arose. I will also mention that if the store you are purchasing from does a lot of business with Rowe, then you will likely have better chances of getting any issues resolved quickly. More clout. Rowe obviously would want the retailers stocking/pushing their lines to be happy and a good retailer should want you to be happy. This is one area where of the smaller retailer can beat out the big box/on line companies.
The last thing I’ll throw out is that there is a wide variance and what people/designers consider to be an “upscale” line. You can buy a sofa for $499.or you can buy one for $10,000. +. So it pays to do some research and find a reputable manufacturer and good retailer that has been doing business for a while. And if you’re looking at Robin Bruce level, you might want to check into the Lee Industries line as a possible alternative. It was probably my favorite company (even though we carried some more expensive lines) for their quality, choices of fabrics and finishing custom options at a reasonable price level. Taylor King also very good but price would be higher yet. Good luck in your hunt.
