I'd like to buy a sofa bed that first and foremost is a comfortable option for actually sleeping on it (I'm planning frequent use). If you have one, can you share your experience? If you know good shops for this kind of stuff, can you let me know too? I'm not quite sure that IKEA will rise up to the challenge!
My Googling revealed Bluebell Sofa Bed as allegedly the best sofa bed for sleeping. But I'm still looking, still thinking... :)
