The short answer is yes. You should order extra units and you should order a few yards of the material. This will keep you going even if someone destroys one of our bar stools. You have the option to reupholster it locally and you can grab one from the back to keep the spot.
Losing seating in a bar is not a good solution. Less bar stools might mean less sales. For a couple hundred and a little bit of storage space, you can be prepared for the inevitable.
Now if you are purchasing furniture from Richardson Seating, you don't necessarily need to buy extra. Our styles don't change and our colors don't change. If you need a single unit 7 years later, we shouldn't have any issue making an exact match. Our digital records go back to 1999, so there is a good chance we will be able to look you up.
We use Naugahyde for most of our jobs and they are still shipping almost all of the patterns that we have been using for 45 years. If you aren't sure what to do, just ask and we can give you the best advice for your specific needs.
