Hi Heather

Thanks for your question,

Your sleeping habits/personal preference will then determine how you would like the mattress to feel in the comfort layers. This is where you will achieve the feel you are looking for (soft/medium/firm). Do you know if you have a preference for a soft, medium or firm?

If you do not, I would advise to go out and try;

Vispring Devonshire - Soft in upper layers - Comparable with the Artisan Luxury

Vispring Regal Superb - True medium in upper layers - Comparable with Artisan Bespoke 004

Vispring Herald - Firm in the upper layers - Comparable with the Artisan Bespoke

[recommended-product post="626331"]

As you are suffering from back pain this would lead me to suggest nothing too firm in the comfort layer as this will only cause the pain to increase, a medium in the comfort layer would be my recommendation for you.

From there, your body weight determines the spring tension you require as shown below

I hope this helps, if you have any further questions please don't hesitate to contact the office on 0161 437 4419.

Kind Regards
