A budget-friendly couch priced around $500 is typically manufactured as fast-furniture, meaning it is designed for temporary use and lighter wear profiles. Under normal daily living conditions, a couch in this price bracket usually lasts between 2 to 5 years. Because they frequently employ lightweight particle board or plywood frames, plastic joinery, and low-density polyurethane foam, the cushions will compress, sag, and lose their supportive resilience relatively quickly compared to premium artisan-built furniture.
