How long do untreated pine outdoor sofas last in rainy environments?

Untreated pine outdoor sofas typically last 1-3 years in rainy environments due to the wood's susceptibility to moisture, mold, and rot. Pine is a softwood, making it less durable than hardwoods like teak or cedar when exposed to constant rain. Without protective sealants or regular maintenance, the wood will warp, crack, and deteriorate faster.

To extend its lifespan, consider applying a waterproof sealant, storing the sofa under cover during heavy rains, or using weather-resistant cushions. For longer-lasting outdoor furniture, opt for treated pine or naturally weather-resistant woods. Regular cleaning and reapplying protective coatings can also help slow decay.

If left completely untreated, expect noticeable wear within a year, with structural integrity weakening significantly by the second or third year in wet climates.
