The cushions are available in the sizes and heights S, M, L and XL. Unfortunately, I can only find out the height of two of the three Millenium cushions on sale. I am looking for a Millenium cushion in size L, i.e. 11cm or XL with a height of 12.5cm. How high is the third one? Incidentally, this is the most important information for these cushions. Unfortunately this is missing!
