Yes, it's oak, and you CAN get replacement cushions! We replaced these a few years ago! We got the couch and love seat over 30 years ago, just before our first son was born, and we built our family room. (first addition) We wanted something kid-proof. It certainly was! When we built the second addition, which added the offices downstairs and our main bedroom/bath upstairs, (the room where the puppies were USED to be the main bedroom!) we moved the This End Up couch into Dave's office (which is really as much "man cave" as office... it includes TV and beer fridge! LOL!) and got the leather couches for the family room. A few years ago I got the new cushions for him for Christmas. They weren't cheap, but they were very good quality, and look SO much better!Ohhhh, so very sweet! 🥰
I spot that This End Up sofa there! We had the same one back in apt. days and LOVED it but they were going out of business as we were looking to replace the cushions. We moved into our home and gave it away. I hope it’s still kicking around somewhere as it was made so well. Not sure if the wood was oak?
