Hi Mcgill,

Thanks for your question.

In the more man made fibre filled mattresses the zip link options can come a little wider, as the spring units arrive at the manufacturers already to size, and then adding the zip and the extra padding on the side can make the overall width bigger.

The Artisan range where the spring units are more hand made and can be adjusted, the zip link mattresses can be made to the correct size of 180 cm wide by 200 cm long for the super kingsize, and 180 cm wide by 190 cm long for the extra kingsize version.

If you require any further assistance please call the office on 0161 413 2265.

Kind Regards, Gary
