Best guest bedroom beds

Top pick: the VIYET 75-inch folding rollaway guest bed. It's the best balance for a guest room — a 5" memory-foam mattress on a heavy-duty metal frame rated to 450 lb, wheels so it rolls out of a closet when someone visits, and it folds flat when the room goes back to being an office or den.

Who the others suit:

• Compact foldaway guest bed — if you want something that arrives fully assembled and stores in a corner; it's the simplest to live with.
• Costway rollaway with memory foam — a similar rollaway in navy if you'd rather match a room's colour.
• Full-size Murphy cabinet beds — if the room must do double duty year-round and you want a real bed that disappears into the wall; these cost more and need wall space and installation.
• Queen bed frame with trundle — if you'd rather have a permanent bed that sleeps two separately when needed.
• SUGIFT folding bed — for a child's room or a very occasional overnight, not for adult guests night after night.

For a guest room used more than a few nights a year, a real mattress on a simple frame beats any folding bed.
