L Shaped Chippendale Bench

I recently purchased this bench on Ebay. I don't know much about it at all. The ownder of the bench was in her 60s and she said the bench was in her parents home for years. It is one solid piece and is 4x6 feet and about 32" high. Besides a few nicks in the wood the frame is in pretty good condition. The 2 seat cushions are spring but have pretty much deteriorated, and need to be replaced. I love the piece and am so curious about the time period it was constructed, materiarl etc..... Any information would be greatly appreciated. Please let me know if you require additional information. Thank you
