When it comes to the framing of metal and leather chairs, you will have two options: aluminum and steel. The best option for you will depend on your preference and budget.
Steel framing makes a chair more expensive, but it will depend on the thickness of the metal that’s used. It’s your best option if you want the most durable type of framing. It’s quite heavy, but it can last several years. Steel is also resistant to corrosion as it's added with chromium. If you will be adding the metal and leather chair in a kitchen or home with kids and pets, we suggest you choose steel framing as it's less reactive to spills.
Aluminum framing may not be as strong as steel, but it’s very light. It's also cheaper compared to steel. As aluminum is soft, it's a favorite among furniture makers which is one of the reasons why there are lots of chairs made of aluminum.
