In your situation, I suggest picking a fabric that will hold up well and easier to clean. That would be a heavy tight woven olefin in dark colors that can hide stains well. For solid colors choose Ultra suede.
R&B is a retailer not a manufacturer and Wesley Hall is a manufacturer.

I should add that many upholstery manufacturers should review their pics and videos on how not to tie a 8-way hand tied coil springs. This includes Wesley Hall and Hancock & Moore. I could name a few others as well. The rails should always be at least 2" below the center height of the springs after tying. This is the proper way to make a good 8-way seat, but it would require more time and more experience to tie this way. As it is now, these 8-way tied coils is inferior to a solid well designed no-sag sinuous wire seat.

Room and board sells a lot of McCreary Modern of Newton, North Caolina.
