LIME GREEN SOFA BED

The sofa that I have at home is a two seater and looks great in my living room (if I say so myself, ahem).  Unfortunately, if I have guests coming to stay I can't use it as a bed as it is simply not made for it.
Now if I have a sofa bed like the one above, then it would just be perfect.  The lime green is also to my taste.  Problem is, I can't think of a place in my house to place another sofa.   So if I have more than two relatives coming to stay, then I'll have to book them into hotels.
