In my old apartment I had a sofa and a bad. It was a pretty big apartment but after that I moved to another city and got a much smaller apartment where I could only get a bed in and I had to sell the sofa.
The lesson I learned from this time is that it is even better if you have just a bed and no sofa. let's take for example a movie night with a girl. When a girl enters your apartment for the first time she will probably feel more comfortable to sit on the sofa than to go straight to your bedroom. However, when you only have a bed and this is the only place where you can sit, she will regard it as totally normal to sit there with you. This leads to her being comfortable in your bed in a very short amount of time.
