The first red bulb" is actually for kids. It's a four piece table and chairs that folds away so it is out of the way when not in use - which is the key to all of this furniture.
Next is a kitchenette designed for urban living. It is compact, fun and easy to maintain. This is not for kids - it's actually a full size eating solution and was actually conceptualized pre-IKEA.
Now we approach the "scoop" circular sofa/bed from Italian manfacturer Saba. I forsee a sheet fitting issue, however a king size will tuck nicely into this..... or if you sew - well add some elastic to a queen sheet all the way around it.
And our final option is from bonbon Trading. This is an integrated / patented mechanism that transforms the sofa into a bunk bed..... guests coming? Now this is one useful setup - for just about anyone
