Two stylish and durable chairs that are really easy to assemble. The metal frames are coated and can be kept clean with a wipe from a damp cloth. The colorful Chili Red fitted seat and back fabric pieces are designed to be weather-resistant too. The only assembly required is to fasten the legs to the seats and backs. This is a simple job and only takes a matter of minutes for each of the two chairs. The backs have some flexibility built in and this helps the sitter to get comfortable easily. All of the fasteners lined up correctly and screwed together easily. The hex key has one flexible ballpoint type end enabling angled fastening.
