I had  asked if the back was metal or plastic and was told it was metal. It is plastic. I bought this to replace a great heavy-duty bench I had for 15-20 years. This bench looks pretty nice and holds 2 average sized people but the back is green plastic, the metal legs and arms are also a greenish color and the seat isn’t very deep. Although it was a real pain to put together (terrible instructions!) it serves it’s purpose and looks nice.
