Our hint for an easy assembly: Put up the folded bed on its feet and pull it apart. First, unfold the short side parts and then the large ones until they properly engage. Only then pull the middle of the floor and then the whole floor down until it reaches a flat and stable position.
When folding the bed, do the opposite. First, pull up the floor and only then unbar the short and then the large side parts. For more info watch our installation video.
NOTE: If the floor is pressed first, the tension is too great and it is no longer possible to lock all joints properly. In case of incorrect operation, the springs may be damaged.
