I'll put my hand up and admit that I've personally made a few of the biggest sofa bed buying mistakes in the past. As such, I'm the sorry owner of a design that's extremely hard to pull open and has a lumpy, bumpy mattress (I'm so sorry to all my guests.)
So, to avoid your embarrassment and their horror as you show them to their less-than-ideal sleeping spot for the night, I've asked a sofa expert to help me identify where the biggest problems arise and what to steer clear of when looking for the best sofa bed to buy. In short, it's worth looking at details like mattress quality, how easy the mechanism is to use, and longevity.
