Flat Weave is the most popular and commonly used variety of rattan used in outdoor furniture. This is a durable and lightweight weaving method that's perfect for regular use. In contrast, half-round and full rod weaves are heavier patterns that can be more durable, but this comes at the cost of significantly greater weight. Generally, this is inconvenient for outdoor furniture sets.  With mixed weaves, it generally mixes half-round and full rod weaves to create a unique look. However, this can result in a wide range of weights and durability. Due to its predictable lightweight and durable nature flat weave is typically the preferred option over these other options.
