I have a super king mattress, can it be resized to kingsize ?

Hi Sherryll Hitchman
 
Thanks for your question, 
 
Unfortunately, there are very few companies that specialise in this field. At John Ryan, By Design, we can make bespoke sizes but are unable to adjust an existing mattress. 
 
I hope this helps if you have any further questions please don’t hesitate to ask.
