Here is one of their newer versions with even more spines. Love it.
Also, in other news, I stumbled across a charcoal gray sofa yesterday on Craigslist that will work perfectly for the new and improved playroom. It's less than an Ektorp from IKEA, and I don't have to mess with shipping costs, etc. It's a Florence Knoll reproduction and screams Mad Men to me . . .
Excuse the Craigslist photo. We went to see it/sit on it today and will have it moved to our house hopefully within a week or so. I think the kids are going to have the coolest room in the house!
