Like Richard said any good upholstery shop should be able to do the job, but would probably require removing the furniture. And they may not want to work on a motorhome.
In Nacogdoches, TX there are a few good places such as Motorhomes of Texas, Infinity Custom Upholstery, possibly Nacogdoches Motorhome Service and the Foretravel factory.
I'm not familiar with any local shops.
