How does cast iron’s brittleness affect its use in lightweight outdoor ottoman designs?

Cast iron is renowned for its strength and durability, but its brittleness poses challenges for lightweight outdoor ottoman designs. While cast iron can withstand heavy loads and harsh weather, its lack of flexibility makes it prone to cracking under sudden impacts or stress. This limitation is particularly problematic for outdoor furniture, which may face rough handling or extreme temperature changes.

For lightweight ottomans, designers often opt for materials like aluminum or synthetic wicker, which offer similar durability without the brittleness. These alternatives provide better resistance to accidental drops or shifting loads, making them more practical for casual outdoor use. However, cast iron remains a viable choice for stationary, heavy-duty pieces where weight is less of a concern.

Ultimately, the decision to use cast iron in outdoor ottomans depends on balancing aesthetic preferences with functional requirements. While its classic look appeals to many, its brittleness may limit its suitability for highly portable or frequently moved designs.
