The Palet Sofa is a neat looking sofabed. Not only are the armrests and the cushions interchangeable and removable, but the entire sofa turns into what looks like quite a comfortable bed.

The Palet Sofa is a red and gray/white sofa with a wooden base. I really like how the armrests can be extended to create higher rests if necessary. The entire sofa bed is one interchangeable piece of furniture, with extra footrests or cushions if the sofa needs to accommodate more people.

It's a pretty innovative couch!
