Help identifying a Dellarobbia sleeper sofa **pictures added**  

I have a nice sofa in good condition made by Dellarobbia. On the cushion it says Dellarobbia pure at least.
I've done several searches looking to try to find the value of this sofa, but can't find a single sofa that looks anything like mine made by Dellarobbia.
The registry no. on the bottom is CA-25018. The arms swing out and lay down into leg rests in the front. The back lays out so that it is then a full sized bed. It is a really cool couch, but I'm just ready for a different look in my living room and need to sell it at it's valued price.
Thanks in advance for any help!
