Before you even start researching models or brands, it is essential to make a careful diagnosis of your own needs.

1. Sleeping position: People who sleep on their side can benefit from a softer mattress with comfort zones that relieve pressure points on the shoulders and hips, while those who sleep on their back or stomach may prefer a firmer model.
2. Health conditions: Allergies, asthma or respiratory problems may require hypoallergenic materials such as natural latex or foams with antibacterial treatments.
3. Temperature sensitivity: If you feel very hot at night, a mattress with good ventilation, such as pocket springs or open-cell foam, may be the ideal choice.
4. Need for motion isolation: If you share a bed, it may be important to opt for a mattress that minimizes motion transfer, such as memory foam models or individually pocket springs.
