Products and service are okay, but the website can do better with regard to size order choices.
Filtering by (1 person) 'Length incl. Tuck-in strip' = '240cm or longer' shows a whole series of products. But if you actually order, the choice is ALWAYS limited to [140x200 / 220cm + 1 pillowcase]. Nothing 240cm, and even one combined 200cm / 220cm choice. The underlying heading Walk-in strip did show 'Double continuous, extra long: total length approximately 240 cm'.
So this is always independent of the chosen product (learned a few samples).
This is VERY CONFUSING! Strong advice to improve the Size selection table, at least something with the numbers 200, 220 and 240 in it as 3 separate choices, if available of course.
The gamble is risky, and the only possible 1-person choice 200/220 selected and ordered.
Eventually received the good product, 240cm incl. Tuck-in strip. I'll say fine, but this is really confusing and a bit of a gamble.
