Hello,
Here is a photo of what your furniture would look like with different upholstery. And, yes, I think it would be alright to do:)
https://auntmaysfurnituresale.wordpress.com/2014/01/30/dining-room-table/HIBRITEN is actually a trademark for BERNHARDT FURNTITURE COMPANY. In 1971, a U.S. federal trademark registration was filed for HIBRITEN by BERNHARDT FURNITURE COMPANY in Lenior, NC. The trademark was filed and then expired in 1993.

"In 1958 a major new product category - upholstered furniture - was introduced with the launching of the Flair division. This new high-fashion look quickly made a name for itself with some of the most sophisticated buyers in America. Flair's creative styling and striking fabrics became a benchmark for others in the home fashion industry. During the sixties and seventies, Bernhardt continued to expand its manufacturing plants, showrooms, and offices to keep up with the increasing demand for its now broad line of furniture."
