Hanna is 66 cm tall and adapts well to most mattresses. The assembly is very simple. It can be folded down 180 degrees. The collapsible bed rail does not need to be disassembled every time it is not in use, but can be set up again immediately. The airy mesh is made of environmentally friendly material and is breathable. It ensures adequate air circulation and allows for constant supervision of the sleeping child. The special Standsafe lock protects against accidental folding of the safety barrier and guarantees that the barrier will not collapse on its own under any pressure from the child. Hanna has undergone a multi-stage testing process and has passed both a series of internal controls and tests at an independent certification body. It fully complies with the European safety standard EN 71-3.
