We featured the Sofia sofa from the same retailer a short while back, but that differs in a couple of ways from the 1960s-style Sofia Mitte sofa bed at Urban Outfitters.
Firstly, the design is different, a more angular take on the button-back sofa in terms of the arm, the back and the base. But perhaps more importantly, the Mitte version also converts easily into an emergency bed. That might be handy if you tend to have friends outstaying their welcome on a regular basis.
The sofa is available in the two colours you see here, selling for £850.
Update: We have just noticed am armchair as part of the same range, which also converts into a bed. You can see that here.
