I have first saw these beds overseas, visiting a friend in Istanbul. It took seconds to convert the sofa into a full bed. It had a full batress, that you do not feel any bed structure, metals sticking into your bones. I was amazing how comfortable to sleep in. I would recommend to anyone who does not need an extra bedroom for their guests. Structure of the sofa (beautiful, classic and comfortable) is certainly strong enough to be used as a regular bed by anyone, not just for occasional uses.
