Yes. The mechanisms in this family convert a sofa into a bed; in Türkiye they are called çekyat mechanisms. There are seven models: [CY-100](https://www.stanmekanizma.com/en/u/CY-100/) Meltem, [CY-200](https://www.stanmekanizma.com/en/u/CY-200/) CSS 3, [CY-201](https://www.stanmekanizma.com/en/u/CY-201/) CSS 3 Lux, [CY-210](https://www.stanmekanizma.com/en/u/CY-210/) CSS 4, [CY-500](https://www.stanmekanizma.com/en/u/CY-500/) Mini Zero, and the [ZK-100](https://www.stanmekanizma.com/en/u/ZK-100/) and [ZK-200](https://www.stanmekanizma.com/en/u/ZK-200/) Z mechanisms. What is the difference between Meltem and Mini Zero? [CY-100](https://www.stanmekanizma.com/en/u/CY-100/) Meltem has three positions: bed and two seating angles, with the backrest opening to 60°. [CY-500](https://www.stanmekanizma.com/en/u/CY-500/) Mini Zero has two: seating (backrest at 102°) and bed. It has an eared bracket foot, fixes with M6 bolts and is widely used in Türkiye. What is a Z mechanism, and which size do I need? The Z mechanism is a sofa bed mechanism common in Europe. It moves the sofa between seating and sleeping and gives access to the storage underneath. Plastic bushings keep it quiet. [ZK-100](https://www.stanmekanizma.com/en/u/ZK-100/) lifts 15 cm; [ZK-200](https://www.stanmekanizma.com/en/u/ZK-200/) lifts 25 cm and has longer arms. Both are available with washers (-P). How many mechanisms does a sofa need? Per the installation guide, [CY-100](https://www.stanmekanizma.com/en/u/CY-100/), [ZK-100](https://www.stanmekanizma.com/en/u/ZK-100/) and [ZK-200](https://www.stanmekanizma.com/en/u/ZK-200/) are fitted one on each side of the frame.
