Outdoor sofas can indeed be used in a cloister, provided they are made from weather-resistant materials and properly maintained. Cloisters, often semi-covered or exposed to the elements, require furniture that withstands moisture, UV rays, and temperature fluctuations. Opt for sofas crafted from teak, aluminum, or synthetic wicker, as these materials are durable and resistant to decay.

To prevent damage, consider using waterproof cushions and storing them during harsh weather. Regular cleaning and protective covers can also extend the sofa's lifespan. Placement matters too—ensure the cloister offers partial shelter to minimize direct exposure. With the right choices, outdoor sofas can enhance a cloister's charm without compromising durability.
