I purchase a LazyBoy Slumber Air sofa that it *exccedingly* comfortable. The mattress not only has a standard sofabed innerspring mattress, but it also has an inflatable mattress on top. Once inflated, you end up with a 10 inch thick, verry comfortable mattress for sleeping that you never know was in a sofa. It is also comfortable for sitting. I believe other manufacturers (e.g., FlexSteel) has similar inflatable mattresses. I can't recommend them highly enough!

Timsmil, I'm about to get an AU Furniture sleeper sofa for my small guestroom/sitting room. They've got an unusual structure that means no 'bar' in your back. I've heard only good things from people who own them. You can search on their site (below) for a store near you where they're available.

Best of all, for my purposes, they are very short front-to-back when they've open. (Like I said, my guest room is *small*.) A typical sleeper is 90-100', within which you only get a 72' long mattress (even in Queen sizes). The AU sleepers are only 83' deep, and within that you get an 80' long mattress, even on the Full & Twin sizes. The long mattress is great for grown-up visitors.

The AU Furniture sleepers do cost more than competitors -- the Full size is about $2000 in microfiber, more in leather (under American Leather brand).

The Crate & Barrel 'Nuevo' sofa is made by AU Furniture and has the same mechanism and virtues. It's bulkier, overall.

Hope this helps!
