The concept of the sofa bed is older than many of us think. The ancient Chinese and Native Americans both realised the space saving potential of something that could be used for both sitting and sleeping. Since then, sofa beds have come a long way but the basic concept remains the same. Sofa beds - as the name suggests - effectively combine two useful pieces of furniture in one. Some sofa beds also offer storage, with a compartment underneath to easily store sheets and cushions. They are particularly useful in small spaces such as flats and for those who may occasionally need an extra bed but don't have the space for it. They are especially useful for overnight guests - especially the unexpected variety - as they can be converted from sofa to bed in a matter of seconds. Today's sofa beds come in a wide range of colours and styles; and you can choose from different fabrics. When choosing a sofa bed, consider the style and colours - but also try to make sure it is comfortable to both sit on and sleep on. Sofa beds can generally sleep two people fairly easily. And one of the most important considerations - consider how easy it is to convert the sofa to a bed and back again. Ideally, one person should be able to convert the sofa into a bed effortlessly.
