Duetto bed by Centro Ricerche Flou

Its versatility is extraordinary; the bed lies halfway between a dormouse/daybed, a sofa and a bed. The daybed version is a comfortable sofa that can rapidly transform into an equally comfortable bed, with an oprional spare bed stored tidily underneath. When pulled-out and raised, it can be anchored to the first one to produce a practical double-size bed. The BOOK Transformable beds – catalogue illustrates Duetto.
