Not all daybeds are suitable as a regular bed. One would need a regular bed that is much more spacious than daybeds. But there are daybeds that you can convert into a full-size bed. Such beds are not only useful as guest beds, but people living in single room apartments can also use them as their primary beds. This type of beds will help them save space and utilise the available space more effectively. They can fold up the bed and use it as a sofa in the morning and use the same piece of furniture as a regular bed during the night.
