Here's some dimensions ....

Because, unfortunately, no dimensions are in the description, I want this late filing here so that others do not even buy the part and return it back because it does not fit. The total width is about 24.5cm above. The total height is about 5cm. The part that rests on the mattress, has a height of about 2cm. The wedge in the bottom center is about 2cm wide and then upwards to approximately, 5cm wide. (Wedge shape) Thus, the wedge was too big for my gap. The bridge did not fit properly. Had ordered underbed me the mattress protector 180x200cm MESANA microfiber, and this alone was enough for my gap to close. You can feel nothing from Spalt.Durch the height of the bridge (2cm) you would notice me more these "sales", as that you can feel the gap between the mattresses. My gap was only about 3cm (at the center to about 1.20 m length) only at the lower end of the gap was about 5cm (as has the bridge better fit). Otherwise, the processing was good. Now hope that with the dimensions looking one or the other equal know.
