Couches during the day for our two, they have their own spots with quilts and blankets. At night they sleep in our conservatory on metal frame beds my husband made (similar to the Coolaroo design). We make removable covers out of sturdy material (vinyl backed curtain offcuts are pretty good) and fleece in winter. The elevation allows for air circulation and for the bigger dog eliminates pressure on his joints. They are also really easy to clean.
