Do you like soft or hard beds? Would you prefer a standard mattress or a foam mattress? If you are not sure, go try out a few different mattress types. Second, consider your budget. This is not a purchase you want to scrimp on, as a poor nights sleep can affect your whole day. Try to get as much value as you can for your budget. Finally, size is a very important factor especially if there is more than one person sleeping in the bed. Ideally, you should both be able to lie on the bed with your arms behind your heads and not touch. A bed needs to be 10-15 cm longer than the tallest person sleeping in that bed. Also pay attention to the height. Lower beds can be easy to get into but harder to get out of. High beds can be hard to get into, especially for shorter people, but very easy to hop out of in the morning.
