A sleeper sofa is a great piece of dual purpose furniture. As with any piece of furniture consider your needs, especially whether it will be primarily used as a bed or seating. There are many manufacturers offering them, with great differences in quality and pricing. Generally speaking, higher priced sleepers are better.
Do You Have Space Restrictions?
Twin size sofa beds might be the perfect answer for you as these are less than 5 feet wide. The mattress for a twin size sleeper sofa is about 39 inches wide, and they are great for sleeping one person. Opened up, the length can be around 54 inches wide and 85 inches long. They are sometimes referred to as chair and a half beds or chair beds also. Don't expect them to be any cheaper because of the size. People usually buy them because of space restrictions.
Do You Need More Room to Stretch?
A full size sleeper sofa is what you need if a twin size seems too restrictive. It can even sleep two. For sitting, its size is between a sofa and a love seat, so it is still an option for a smaller space. A full size sleeper is 72 inches wide, and approximately 90 inches long when fully opened.
When Space is Not an Issue
