Outdoor furniture and indoor furniture differ in several ways.

Firstly, outdoor furniture is designed to withstand exposure to the elements such as rain, sun, wind, and snow. Therefore, it is typically made of materials that are weather-resistant and durable, such as metal, plastic, wood treated with weather-resistant finishes, or synthetic materials. Indoor furniture, on the other hand, is designed to be used in a controlled environment and is typically made of materials that may not hold up as well under outdoor conditions, such as untreated wood or upholstery fabrics.

Secondly, outdoor furniture is often larger and bulkier than indoor furniture. This is because outdoor furniture is typically used in open spaces where size and scale are not as constrained as in indoor spaces. Indoor furniture, on the other hand, is often designed to fit within the limited space of a room, and is typically more compact and streamlined.

Lastly, outdoor furniture often has more casual or relaxed designs, while indoor furniture is often more formal and decorative. This is because outdoor furniture is typically used for leisure activities and relaxation, while indoor furniture is often used for more formal occasions or as part of the decor of a room.

Overall, while both types of furniture serve the same basic purpose of providing a place to sit or rest, their designs, materials, and purposes are tailored to their specific environments.
