A bed is generally the most prominent piece of furniture in the bedroom and can set the mood for the entire space. Beds can also be a big purchase, and one that will last for a considerable amount of time. Consider the type of feel you want to create in your bedroom as well as the amount of space, and use that as a guide to help you choose a new bed. Beds increase in the following sizes, Single, Double, Queen and finally the King size bed. It may be worth noting that the Queen size bed is notoriously difficult to buy fitted bedding for.
