Now days everything is expensive and even cotton microfiber or nylon is up there.
Even cheap costo sofas are expensive so its hard to label whats cheap now days based on cost.
In my opinion and experience a customer will say it cost so much and its from pottery barn, room & board or Ashley, macy, jc penny it doesnt matter who you bought it from the tag is 80% inaccurate.
Test the fiber. thats the only way .
Even if it was re upholstered, Ive had folks tell me that its a "good" fabric, it was expensive to re cover.
Nope, many I repeat many times ive encountered Sissal, Rayon and it was expensive. expensive isnt good quality.
Even upholstery shops dont know about textiles. I sure wish they would take a class.
