Here's one possibility

IKEA, as you could probably guess, makes a zillion types of space-efficient and stylish lounging solutions. The one pictured here is from a group called Kramfors.

There are a lot of different pieces that can be mixed and matched. Sooz likes this black/white fabric as the pattern won't show too much dirt and it's color-neutral. (She wants to add her color with rugs and pillows, etc.)

It's also pretty inexpensive; remember, this isn't a year-round couch so we don't need anything too hard-wearing. It would be nice to have a sofa bed but we haven't seen one that we like the look of yet.

We'll look more in February but our goal is to have whatever we choose delivered in Easter when we're there for a week.
