Room and Board has (9) "sleeper sofas". You'll have to look at styles to see if anything might work....
What I liked and wanted for myself (though not technically a "sleeper sofa") was the Room and Board sofa "Encore". The back cushions go down. Unfortunately the market has been flooded with a lot of "cheap knock-offs" of this look. Room and Board quality in general is good. Sofa probably comfortable for a night or two but, not long term. This item 82" in length.
Some companies make "sleeper chairs" but, don't have a specific manufacture to recommend
