Thank you for your question.  In short, there is no way to have one tension of mattress to meet both your needs, not without compromising both of your requirements to some degree. Based on the weights I would normally recommend the 10 stone choose a medium mattress like our Fusion 3 which will allow pressure relief but enough support for this weight, but the 17 stone sleeper would find this too soft (especially as your current Dunlopillo mattress is comparable with the Fusion 6 which is our firmest latex mattress.  Unfortunately, we can not provide a split tension or zip and link option in this range.

Our Origins Pocket Latex 1500 combines a quality pocket sprung unit with a deep Talalay latex comfort layer giving it both a progressive comfort with a traditional support. It has a medium firm feel and has the option of dual spring tension, one side medium for the 10 st person and one side firm for the 17 st person.  There is also the zip and link option.  Both these options are available in King Size and above.

If you would like to discuss the suitability of this mattress or anything else, call our friendly team 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
