Hi Donna,

We do not make mattresses for anybody else and we only sell our own products.

Zip and link mattresses are made as a pair so that the zips align perfectly, which is why John Lewis will not sell you one half. I am afraid you will either need to buy a new set or you would have to purchase a new single mattress.

I hope this helps if you have any further questions please don't hesitate to contact the office on 0161 437 4419

Kind regards.
