There a few different factors to consider when chosing the comfort feel of your new mattress- body weight, sleeping position, the type of bed base and your personal preference.
Soft mattresses are suitable for children and very light people who enjoy sinking into the bed.
Medium comfort is the most popular choice and is recommended fo the average person with body weight up to 90kg.
Firm mattresses are good for bigger and heavier people with body weight over 90kg.
Side sleepers prefer softer support to allow the shoulders and hips to sink deeper into the bed.
Back and front sleepers find firmer beds more comfortable as they offer better support for the lower back and spine.
The bed base is also very important and works in harmony with the mattress. The same mattress feels firmer on solid bases and softer on sprung bases.
