Here are the main factors to consider: when you buy a mattress
• Your sleeping position
Side sleepers: Medium to medium-soft mattresses that cushion the shoulders and hips.
Back sleepers: Medium-firm mattresses that support the spine while providing some contouring.
Stomach sleepers: Firm mattresses to help keep the hips from sinking too far.
• Mattress type
Memory foam: Excellent pressure relief and motion isolation.
Hybrid: Combines foam with pocket coils for support, comfort, and airflow. A great choice for most people.
Innerspring: More bounce and a traditional feel.
Latex: Durable, responsive, and naturally cooler than memory foam.
• Firmness
Soft: Best for lighter individuals and many side sleepers.
Medium-firm: The best overall choice for most people.
Firm: Often preferred by stomach sleepers and people over 230 lb
• Temperature
If you sleep hot, look for cooling foams, breathable covers, or a hybrid mattress with pocket coils.
• Motion transfer
If you share a bed, memory foam or hybrids with individually wrapped coils help reduce movement from your partner.
• Edge support
Strong edge support makes it easier to sit on the side of the bed and provides more usable sleeping space.
• Try before you buy
Spend at least 10–15 minutes lying in your normal sleeping position. Your spine should feel supported with no pressure points
