Its not uncommon to find some differences within the same manufacturers same line of upholstered sofas using the exact same leather. You see a upholstered piece on a showroom floor and order the exact sofa and in the exact same leather from that manufacture, but when the sofa arrives in your home, you feel that they must have given you a completely different sofa. It sits different, the leather doesnt feel the same, it doesnt look the same as the showroom sample and you think that you made a bad purchase decision. When if fact it happens more often than not. Upholstery is more art and leather is a natural product so more than anything else their will be variances. Pick a sofa based upon the manufacturers construction method, attention to detail and materials used plus how their warranty compares for equivalent priced sofas. Leather is an investment, so the need for doing some basic research to understand these important aspects.

Be careful they are in financial trouble and some believe on the verge of going bankrupt.

I discovered this rating chart years ago, and see that it has been updated over time to add other manufacturers. I don't see the two that you mention listed, but it's a good link to bookmark. Here is a link that might be useful: List of most Major Leather Brands and where they rank as far as quality in the industry.

I am an interior designer and have recently been very disappointed with the quality of Norwalk upholstery and the unwillingness of the company to rectify issues. My client purchased a sectional and within 3 weeks of delivery a hole on each corner of the arm has appeared where the fabric has rubbed against nothing but wood. There is no padding in between the fabric and the wood and the fabric was not backed to prevent this. The other issue is puling of the fabric on the side of the sectional near the back corner creating a ripple effect. The company has refused to fix these issues. I have a very unhappy client and would not recommend them.
