Direct Answer
Kolkata's monsoon (June-September, 150-200 cm annual rainfall, 80-95% relative humidity) is one of India's most demanding for furniture. Key protection protocol: run a room dehumidifier during peak monsoon reducing humidity from 90%+ to under 65% for the living room sofa. Weekly: lift sofa cushions for 30 minutes to allow air circulation underneath. Monthly during monsoon: inspect cushion undersides for any mould beginning to develop, treating immediately with diluted white vinegar. For leather sofas: increase conditioning to monthly during monsoon and apply anti-mould leather conditioner specific to coastal conditions. All Kolkata furniture should have anti-mould treated foam — this specification is more important in Kolkata than any other Indian city. SOISU applies anti-mould foam treatment as standard on orders for Kolkata delivery.
Kolkata receives 150-200cm annual rainfall concentrated June-September with 80-95% RH during peak monsoon. 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.
Anti-mould foam treatment and weekly cushion underside inspection are the most important Kolkata-specific precautions. 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.
