Hi Vanessa,

Many thanks for your question about finding the right level of support in a mattress for a heavy sleeper. It can be a minefield when looking for a bed for a sleeper who weighs 18 stone mainly because most retail mattresses support stops exactly at 18 stone.

Most people confuse support vs comfort when shopping for a new mattress. But we can help clear that up here and give an idea of a suitable mattress to meet your sleeping needs.

Mattress Support Explained:

Mattress support is provided by either a pocket spring unit (like our mattresses) or a slab of reflex foam (firm man-made foam). It should always be based on your bodyweight and not the comfort or feel of the mattress. Mattress comfort is provided by upholstery on top of this mattress support unit.

The video guide below on spring tensions helps explain in more detail. Alternatively, the mattress support table will help show you which spring tension each sleeper needs, in your case a 1.6 gauge for both sleepers.

Mattress Comfort Explained:

Mattress comfort is always provided by the upholstery fibres or layers of natural fibres that are built up on top of the pocket spring or support base. The type of materials, GSM (Grams per square meter) and order in which they are layered all make a difference as to how firm the comfort of the mattress is.

The GSM is super important when looking for a new mattress as it allows you to then compare models. Have a look at our mattress compare tool to see how to accurately compare mattresses side by side.

Softer fibres create a soft feel mattress. Firmer fibres will create a firmer feel mattress etc. Have a look at the table below to see how different fibres feel - take note that the way they are layered and with which other fibres will change and tweak the overall feel.

Firmer feel mattresses for heavier sleepers:

Below are two of our mattress models to help start you off if you want a firmer feel but with deep comfort layers for shoulders and hips. The Artisan 1500 is the softer of the two if you're concerned with the Artisan Bespoke our firmer 100% natural fibre mattress.

The Artisan Bespoke is the firmest 100% natural fibre mattress we can provide. This mattress paired with a firm 1.6 gauge pocket spring tension based on your body weight to ensure you are correctly supported underneath the natural fillings.
