If you are buying an apartment for the first time, do not skimp when it comes to the bed.  Even if you want to go with a bit smaller bed, make sure that it is high quality.  Make sure that you look at multiple mattresses, bed in a bags, and box springs before making your final decision.  Because you spend so much time in the bed it is important that you get a good nights sleep, and the best way to accomplish this is through a high quality bed.  There are so many choices out there, but make sure that you do not go with the lowest quality model or you very well may find yourself with back pain.
