Hi Adrian,

Thanks for your question, It is a really common one and an area of mattress selection that 90% of people get wrong! That part is spring tension selection when buying a new bed.

When choosing a new mattress 90% of the time buyers mistakenly pick the spring tension as the 'overall comfort or softness feel' of the mattress. Ie they choose a firm spring thinking it will give the mattress a firmer feel overall or they choose a soft spring for a soft feel in the top layer.

The issue with this is that spring tensions are designed for bodyweight ranges and not the feel of the mattress. The majority of the true firmness feel of the mattress comes from the upholstery layers on top of this spring unit. Sure a firm spring will make a bed feel firmer in the initial support but not the comfort layer ie upholstery which is the main sleeping area of the bed. Which is why choosing the right comfort layers is essential.

Spring tensions are manufactured for 3 distinct weight ranges below:

At 18 stone we would recommend you choose the appropriate 1.6 gauge firm spring but then look for soft comfort layers in the mattress. This is where most retailers fall short. As they mistakenly only list the spring tension consumers end up buying the wrong support in a mattress which is either too forgiving ie you sink too much or too punishingly firm.
We list all of our comfort layers, the Grams per square meter and all other details that most retailers fail to disclose to mattress shoppers.

If you're wanting a medium feel mattress then please look at our Artisan Bepsoke 004. Hand crafted with 100% natural fibres and vanadium coated pocket springs, this tailored sleep experience includes an additional layer of breathable bamboo providing a true medium feel two sided mattress.

If you're looking for a super soft mattress then check out our Artisan Luxury. I love a soft mattress and have this one for a very deep sink. Like all mattresses, it will need turning each month, especially as it's soft. You really need to want a very deep sink if you choose this model as a word of caution, but a fantastic mattress.

Alternatively, you could add a soft topper to the Artisan Bespoke 004 which can be removed and replaced when necessary. A topper will allow you to soften the top layer, never firm it up (another retail myth). So that model may give you the most options. Here's a handy table to help you see which fibres are soft and the price point to guide you with mattress selection.
