Hi Diane,
 
Thank you for your question on our website.  Zip and links are an ideal solution when there may be an access issue getting your new mattress to the room of your choice or when there is a difference in body weights and two different spring tensions are required.  Spring tension is based solely on your body weight to give you the correct level of support.
 

 
Both our Origins range, which is our synthetic fibre range and our Artisan range, which are constructed using natural fibres, have the option of zip and link in King Size and above.
 

 
The size you require is not a standard size that we do but we could make this as a bespoke size item.  There would be an additional cost of 10% per 6-inch increment of change and there would be no ’60 day love it or return it’ guarantee on any bespoke size item purchased.  In order to make a recommendation, we would need to know your body weights, your comfort preferences and your sleeping habits.
 
If you would like any further information or to discuss the suitability of any of our mattresses please do not hesitate to contact the office on 0161 437 4419.  Our office hours are 8 am – 8 pm Monday to Friday and 10 am – 4 pm Saturday and Sunday.
 
Kind Regards
Michaela
