Sheets for Vispring

[2MuchAlready]

Does anyone else have a vispring zip& link mattress? If so where do you buy your sheets? I just measured and my bed is 200cm long but seems to be just over 210cm wide (this is when I've really pushed the matresses together. All the fitted sheets seem to be 200x200.

I can’t remember the name of the company, but do google made to measure sheets. We have an odd sized bed, between king and super king (Vi Spring in a sale ages ago) and I had some fitted sheets made a couple of years ago, pure cotton. They were more expensive but not ridiculous. It was a co. in Yorkshire IIRC.
I was unable to find ready-made anywhere.
