How much should I spend on a sofa?

Match the spend to the years you need. Under $700 buys fast-furniture with webbing suspensions and low-density foam — fine for a short lease, tired by year three. The $800–$1,800 band is where kiln-dried or plywood frames, sinuous springs, and 1.8+ lb/ft³ cushions appear; that is the sweet spot for a daily sofa you keep seven to ten years. Past $2,500 you are buying premium suspensions, better fabrics, and brand. Whatever the price, the frame material, suspension type, and cushion density printed on the spec sheet tell you more than the showroom sit.
