Because it is even more fun to receive people if you can offer them overnight. Who knows, you give a party once and some people come from far away. It is of course an option to put a west elm sofa bed in every extra room in the house. Or you can buy loose mattresses to lay on the ground. The big disadvantage of this is that this takes a lot of unnecessary space in the house.
A mattress is difficult to roll up or in a different way smaller and you just have a shed where you can lose the loose mattresses. And then you still have the west elm sofa bed but also for this applies: you just have room for it. These are again much harder to tell so if you have them in a shed, chances are that you need to do a lot of construction work because the folding beds often come with an extra construction (for example, wheels underneath).
You will soon end up at a west elm sofa bed. An extra comfortable sofa bed will come with a price tag. This sofa bed is designed by Per Weiss. When you fold it out you have a generous bed of 200 by 140 cm. If you want to make the bed extra comfortable, order a topper!
