For sitting, the size of a full sized sleeper is between a sofa and a love seat, rather like an apartment sofa, so it is still a good option for smaller spaces and apartments. You will find that a full-size sleeper is generally about 72 inches wide, and approximately about 90 inches long when fully opened. There is no simple, easy yes or no answer to this question because the answer depends on several factors. If you are planning to reupholster an old sofa then you should really consider them before you commit to an expensive undertaking.
As there are many manufacturers offering sofa beds, you will notice great differences both in quality and pricing. Needless to say, buy the best quality you can afford. Often sleepers in higher price points are also better made. If you have a very small space then Twin size sofa beds might be the perfect answer for you as these are less than 5 feet wide and they are great for sleeping one person. The mattress for a twin size sleeper sofa is about 39" wide.
If you plan to use it as the primary sleeping surface for yourself, look into the type of mattress that comes with it. As you are no doubt aware, sleepers come with many different types of mattresses, some using specialty materials, some come with inner-springs and others are air beds. Try and find one with a mattress type you are happy using. Also look for a mechanism that opens and closes easily.
