Best sleeper sofas for guests

Top pick: Koala Sofa Bed (4th Gen) — the one I'd put guests on. It's a real sofa by day and a queen-size bed by night, and thousands of ratings back up that it holds up to nightly use. If guests sleep over more than a few times a year, this is the one worth stretching for.

Who the others suit:

• Cushie 2 Seater Modular Sleeper — a queen memory-foam sleeper in a compact footprint; best for a small guest room or studio.
• West Elm Shelter Sleeper — the most furniture-like of the bunch; pick it if the sofa has to look good in a main living room.
• Mahoney Sofa Sleeper — a solid mid-range traditional sleeper with strong ratings.
• Anpport 3-in-1 / Wiilayok / GAOHAPY convertibles — cheap, small-space fold-outs for occasional one-night guests; fine for a teen's room or a den, not for a week-long visit.

Whatever you choose, check the mattress type and the open length against your room before buying.
