We are all set to look for a sleeper sofa for the 3rd bedroom in our CYV - a Bonita/Foxglove plan. It's not a huge 3rd bedroom, we use it for an office/music room (Ohioboy is a cornet player and practices occasionally, so we leave his music stand out and he uses the desk chair).
Then - my kids gave us a high quality queen-size airbed (Aero brand). Inflates and deflates in about 5 minutes. Quite comfortable. We have slept on it 4 or 5 times. It's one of those double mattress ones, about 20-24 inches high (I've never measured).
We decided a sleeper sofa would really cramp the room, wouldn't have a good place for the desk and a recliner that migrated into that room, and the restored jukebox my brother-in-law gave us (until I kick the bucket, but good luck getting it back from Ohioboy if I go first).
Plus, we can take it back and forth to Ohio and wherever we might visit in our retirement travels. Our friends are all starting to retire in different places, and it's kind of fun to get 3 or 4 couples together sometimes for a weekend visit. We feel more welcome when we can bring our own bed
