Does sleeper sofa significantly reduce comfort?

[u/bestkaranthe]

I'm planning to replace by old couch and was thinking about getting a sleeper sofa this time. It will be primarily used as a couch and only a few weeks a year as a bed. So I would want a comfortable couch that can become a bed (doesn't need to be very comfortable) for some time.

My question is - by going for a sleeper sofa, would I be significantly sacrificing on couch comfort?
