Convertible couch beds are great if you are having a couple over to stay and have the space to fold out into, but these double-decker solutions is a great alternative for smaller apartments or multiple-but-single overnight guests. Here are three designs from different companies that show off the potential of this strategy (and give you a few color, size and style options to choose from, too).

First, the Coupe deploys as fast as a regular transforming sofa, but expands vertically rather than horizontally to create a pair of beds stacked on top of one another. Based out of Greece, Proteas is a 50-year-old furniture company specializing in high-end designs. The Coupe comes in blue, red, green, brown or beige.

An alternative option that transforms slightly less quickly but unfolds along similar lines (and may be more robust due to its use of side supports) is the DOC.

Designed by BonBon, a UK company, it likewise lifts up to reveal a ladder and second-level sleeping area for guests, starting as a sofa. The DOC comes in in red, purple or orange.

Finally, from Resource Furniture, “the Palazzo bunk bed system, an innovative design that transforms from a sofa to a bunk bed, provides multiple functions while maximizing space. The beds are available with low or high armrests and come equipped with wood-slatted bed springs and removable mattresses. The bunk bed system includes exceptional safety features, including a locking mechanism and a complete barrier around the top bunk.”
