Do you mean a click clack sofa that converts to a bed? Like these https://www.wayfair.com/keyword.php?keyword=click+clack+sofa+&command=dosearch&new_keyword_search=true&class_id=

I have a sofa/futon very similar to the one terriks linked above from wayfair. It is very hard and uncomfortable to sleep on. I had to purchase a 3" foam pad to make it 'sleepable'. For sitting, it's OK. The seat is not too deep. It's in a rarely used room so I keep it.

Yes, terriks, thank you! That's what I meant. :)

Thank you, czarinalex! I currently have a day bed in the guest room, which is impossible to use as a sofa. We have an overnight guest about once every five years, so I'd really like something comfortable to sit on that could be used as a bed once in a while. Ideally I think I'd like a sleeper love seat.

Ikea has some surprisingly comfortable sleeper sofas because they don’t use a foldout mechanism with bars.

They can be amazing. We had several..they're much more popular with urban living. Then it was long time ago, in Europe, and they were extremely well made.

My click clack I bought for our first tiny living room, so can be used as sleeper too, now stands at my Mom's, 20 years after, and is heavily used by guests-it's comfortable like any great mattress would be, it's great to sit on too.

My guess is one can find something similar, it'd just be very expensive. Even bad new sofas are expensive..what to say about good ones)) It won't be 500. would be more like 2-3 K. And most likely lean to be modern in style(which I love but not everybody does).

I researched them myself...my favorite was 3,5 K so I drastically changed my wants and went with a daybed I found on Craigslist lol

There are always exceptions..my friend has one I use when I come to visit her and it s quite comfortable, and she told me it was cheap. But then it also was bought 15 or so years ago. And they, she didn't remember who "they" were lol, didn't carry it anymore)

Or one can look for vintage..

We have one that is very similar. However you need a thick foam mattress topper and then it is perfect. Basically it is like sleeping on a carpeted floor. Anything will feel good that is firm with a nice thick mattress topper on it.
