Hi! Well so far I have not seen a crafting recipe for a couch. There may be one in the higher levels I have not been to yet however. I am in Avalon right now. I have seen plenty of other furniture though. Having a couch you could craft would be very nice.
I don't know of a couch to craft, but that would be awesome!
There is a sette red seat with black back and a royal sofa red seat with brown back. I know the royal sofa can be purchased from the Bazzar or a furniture vendor. Unsure about sette if purchase or just a drop. The other place to get a couch is the crown shop. There are furniture sets that have couches themed after different worlds that you can buy with GOLD, you just have to click buy with gold.
