One of the most exciting things about getting your own apartment is decorating it. Finally, you have a space that can reflect your taste. Unfortunately, renting an apartment means that your ocean of ideas may not fit into the space. Instead of going overboard buying furniture, focus on a few pieces you'll really need and your space will start to come together. 

Before searching for any furniture, measure your apartment to determine how much space you have. Then, think about how you'll use your apartment and use this information to prioritize furniture purchases. If you eat dinner in front of the TV, don't spend a lot of money on a big dining table, for example. 

This sounds incredibly obvious, but the most important piece of furniture you can spend space and money on is your bed. When buying a bed there may be more to consider than you thought. First of all, determine what size you'll need and what size will fit. Even if you can go large, it doesn't mean you should. You'll want room for other furniture too. The size of bed you choose might be influenced by whether or not your partner will be sharing it. If you're single, you can get away with a twin, though a full is more comfortable. If you  are part of a couple, a queen will give you both the room you'll need.

Shop around online for your bed but buy it in the store. This will give you an idea of how much you need to spend. When you get to the store, you can test out your different mattress options.

Anyone with a computer – so pretty much everyone – is going to want a desk in his or her apartment. While sitting on your bed with your laptop can be cozy, there are those days that sitting at a desk makes getting work done easier – even if that just means intense social media use. If you're the type who likes to stay organized, consider purchasing a desk with drawers. That way, all your "office" supplies can stay in one place. 

You want to make sure the surface of the desk has enough room for everything you do. Your computer monitor or laptop should fit alongside whatever papers and supplies you like to leave out. Do you like to keep your printer on your desk as well? When you're at the store, sit down in front of the desk to make sure it feels comfortable. 

While you may not want to spend a lot of your apartment space on a sofa, think about how it will be used. If you entertain frequently or have friends spend the night, a big couch is a must. You'll want space for guests to sit or crash, if need be. If your friends sleep on the sofa often, consider a futon instead. This way, your furniture has multiple is versatile. Futons allow you to get more use from your space. 

If you don't entertain much, you may want a small love seat or just a couple of comfortable chairs.
