I completely understand what you mean, this could have been a pricing error - has been changed in any case. For smaller price differences, it could simply be different supplier conditions. But the difference you describe doesn't make sense to me either (apart from a possible price error).

In the WOOD colour version, the height is given as 36cm in the description, unfortunately not for WHITE.

Dimensions: L 120 cm, W 32 cm, H 40 cm.

Above the field where the question is written, it says the following: "If you have questions about this product, you can ask them here. If you have a question about an order, please contact customer service directly."

It should fit every bed, as long as the mattress isn't over 19 cm high.
