Hi Geraldine,
 
The total weight of an Artisan Naturals king size mattress is 60 Kg due to the amount (GSM) of upholstery we put into our comfort layers.

If you have difficulty turning and rotating a king size mattress it may be beneficial for you to consider a zip and link option. With a zip and link mattress you can simply unzip the mattresses, flip each one from north to south and then zip them back together.  Zip and link mattresses are also ideal if you require two different spring tensions or if you have access issues getting larger mattresses to the room of your choice.
 
I hope this is helpful and if you would like any further information please do not hesitate to contact the office on 0161 437 4419.
 
Kind Regards
Michaela
