Dellarobbia sleeper? Help!!

[Abrew]

I have a sofa in good condition made by Dellarobbia the I got from a guy through Craigslist about 2 years ago for $100. On the cushion it says Dellarobbia pure. He bought the sofa from Cantoni and was updating his house and wanted new furniture.

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 so I can get something more my style. PLEASE HELP

Thanks in advance for any help!
