Assembly Instructions Step12 Assembling slats Please fix the first slats 5 at the end of the rail and work towards the middle of the bed using the spacer N and R as shown to ensure correct spacing. Note that for first slats, spacer R should be used in the middle and spacer N at the sides as shown in the drawing. Fix slats in one side first, then fix them in the central rail by pushing the rail against the slats if necessary. Repeat in the other side rail.
