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.
Lighting is a big deal when it comes to the feel of the room. Subtle changes in the lighting can make big differences. There are lots of ways to do that other than the standard light that you have currently. The easiest way is through lamps, either through table or floor lamps. I prefer floor lamps because you can move them about the house easily and experiment with how they look in different positions.
If you are happy with your current light fittings think about lamp shades. It is simple to change a lamp shade but they too can influence the feel of the room. Before you do that though just think about the effects they are likely to have. When most people think of living room ideas they think of furniture. This doesn't mean that you have to go out and buy new things. You can make a big difference by moving what you have around. This should be relatively easy and save you some money.
