Hi Sue,

With your body weights you do fall within the medium spring tension range, however, I note that you both have had difficulties with such a mattress on a sprung base. Notwithstanding your issues,  I would normally recommend that you look at our Artisan range in a medium spring tension.

Please view the details of our Artisan Bespoke 004, which should be selected in a medium spring tension, as with it's upholstery layers, it will provide a slightly firmer feel. Zip and link mattress set are normally reserved for people who may have access issues for a one piece super king or require a split tension in a combination which could not be provided in a one piece. Additionally, there is the price to consider and if your budget is currently the same as your previous purchase, you may wish to consider a king size one piece meaning that you could retain your current base.

I trust that this helps, but if you require any further advice, please call our office on 0161 437 4419.

Kind Regards
