Unlikely. Our sofa is like $300. Let's say it only lasts 3 years before it shows wear or we get bored of it and get another $300 one... your $5k sofa would have to last for 50 years to 'save money'. Not to mention the opportunity cost of those funds.
Pay for quality if you want quality, not in an attempt to save money.
