Choosing among many types of transformation of sofas, you need to consider whether you will lay out a berth daily, or only occasionally, when guests rush into the house.
Book ("click-gag")

- As a rule, it is possible to provide a linen box.
- The berth is flat, without "excesses".
Eurobook

pros
- Durability: Simplicity sofa folding mechanism excludes breakdowns.
- Large selection of sizes.
- A large linen box due to the lack of internal parts of the mechanism.
