Where Does the Larssen Deep Seat Sofa Work Best?

This three-seat outdoor sofa fits naturally on covered porches, screened lanais, pool decks, and open patios where full-size seating is needed. The powder-coated aluminum frame resists corrosion in salt air, maintains structural integrity through temperature extremes, and requires only periodic cleaning with mild soap and water. Pair it with pieces from our outdoor accent chairs collection to create flexible seating zones, or complete your setup with selections from our all outdoor furniture range for coordinated patio arrangements.

How Do Sunbrella Cushions Perform Over Time?

Sunbrella cushion fabric carries a manufacturer warranty against fading and staining, handles everyday spills with simple soap-and-water cleanup, and can be machine washed in cold water when deeper cleaning is needed. The cushions resist mildew and water penetration, making them suitable for humid climates and covered outdoor spaces where moisture lingers. For long-term care, machine wash covers in cold water with mild detergent, air dry only, and store cushions in a dry location during extended periods of non-use.
