Response from Brian & Lotte:
Thank you for the positive review. I agree with you that the sofa is a bit on the firm side, but some people actually prefer that. The Puzzle sofa is produced by the Danish Design company Innovation. I love its flexibility in that if offers two sitting positions for the back, and that it folds down to provide the base for a very comfortable second bed. We still think it is the most efficient and visually attractive "design compromise" between a sofa and a comfortable sleeping space, so we will keep it.
