A Pull out couch often called a sofa bed or a bed couch is actually a sofa couch which has a metal frame with a thin mattress under the seating cushions than can be unfolded and pulled out and arranged into a bed. You can select a pull out couch from a large choice of styles and colors available in the furniture stores. In certain sofa beds there is built-in storage and at times you can even choose the type of mattress that suits you.
A sofa is a common piece of furniture in the living room, but it can be a perfect arrangement if this sofa allows a dual purpose like seating arrangement during the day and an extra bed for the night. It is quite flexible and advantageous in places where space is limited. Usually pull out couches look just like normal couches until you pull out the bed.
The cushions are removed and a tri-folding metal or wooden frame and mattress is pulled out to make a bed. When not in use the frame and mattress is easily folded back into the sofa. Another good point is that since the pull out couch or sofa-cum-bed looks like an ordinary sofa, you can buy one matching with the other furniture in the room.
One problem with these pull out couches is their excess weight. Due to these couches being very heavy it sometimes becomes difficult to move them through narrow doorways or up the stairs.
