A daybed is a type of bed that can be used both as a sofa and as a bed. Daybeds are usually made with a metal frame and a mattress, and they often have a built-in trundle bed underneath. Many people use daybeds as guest beds because they are so versatile. Some daybeds even come with storage drawers beneath the mattress, which makes them even more practical.
There are several pieces of furniture that are similar to daybeds. Futons and sleeper sofas are two common examples. Both of these pieces of furniture can be used as both beds and sofas, and they often have trundle beds or storage underneath. However, futons tend to be smaller than daybeds, and sleeper sofas usually have springs or coils in the mattress instead of foam or another type of material.
