The Tempress 48" Folding Bench Seat is the same that we make for our Boat Building Customers. It is made with a light weight corrosion proof aluminum frame back and a heavy duty plastic base. This allows for extreme durability, light weight, and easy installation in a wide variety of configurations. The 48" long bench seat folds with black powder coated hinges, and is covered in 30oz marine grade UV stable vinyl. The high density foam inside provides perfect support and cushioning for those days when the weather gets rough. Dimensions are 48"L x 19"H x 20"D. Mounting hardware is not included.
