A medium tension mattress like this is the goldilocks of mattress tensions. Not too soft, nor too firm, medium is typically suitable for the vast majority of people that are looking for a good nights sleep. If you are of average build without back or neck problems, this should be a suitable product. If you are of lower BMI and a side sleeper, consider a softer mattress, whereas if you are of a higher BMI and suffer neck and back pain, consider a firmer tension.
