- Motion Isolation: If you share a bed, consider a mattress that minimizes motion transfer to avoid disturbances from a partner’s movements during sleep. Memory foam and some hybrid mattresses are particularly good at absorbing motion.
- Temperature Regulation: Some materials retain heat, which can disrupt sleep. Look for mattresses with cooling technologies, like gel-infused foam or breathable covers, to maintain a comfortable sleeping temperature.
