To save more on space, especially if you got a small, cramped studio unit, you can consider getting a sofa set that can double as a sleeping mattress. Commonly called sofa beds, they can be converted to a seating furniture sofa and to a bed that you can sleep on such as a futon sofa bed.
If you are one of the latter then what you can do is to make the place as cozy as possible through well-planned interior design and the use of practical yet comfortable furniture.
The beauty of these things is that they are so versatile and useful but they can also be stylish and elegant. Of course, the prices will be directly proportional to how comfortable and stylish they are but you definitely can acquire a well-designed and functional unit at any price point. For maximum comfort, get the high end models that sport really thick mattresses and spring foams. For maximum affordability, you could go for the thinner mattress futon sofa types which are sometimes considered to be disposable beds.
