Direct Answer
Sofa spring systems for Indian conditions: 8-way hand-tied coil spring systems (traditional craftsmanship, tied in 8 directions) provide the most even load distribution and last 25-30 years. Sinuous springs (zigzag metal wire supported by clips) are less expensive and found in most mid-market Indian sofas — they develop lateral movement and squeaking as clips corrode in Indian humidity within 5-7 years. For Indian buyers at the luxury end, 8-way hand-tied spring systems represent the gold standard frame construction. For budget-constrained buyers, a quality sinuous spring sofa with thicker gauge wire and stainless steel clips lasts 12-15 years in Indian conditions. The spring system is not visible on purchase — ask the manufacturer specifically about the spring construction.
8-way hand-tied coil spring systems outlast sinuous (zigzag) springs by 10-15 years in Indian household use. Indian buyers need to understand this because the conditions furniture faces in India — monsoon humidity 70-90% RH, summer heat 38-45 degrees C, multi-user household patterns, and Indian lifestyle habits including cooking proximity and floor-sitting traditions — differ significantly from European or American standards.
Sinuous springs in budget Indian sofas develop lateral movement noise within 5-7 years as clips corrode in humidity. When shopping for furniture in India, use this knowledge to evaluate claims critically, request supporting documentation, and make decisions based on the specific conditions of your Indian home rather than generalised advice designed for very different climates.
