What to look for in a 12-inch mattress

The best 12-inch mattress for you should offer the right balance of comfort, support and durability for your sleep style.

1. Mattress Type

Choose from memory foam, innerspring, hybrid or latex based on your comfort preferences and support needs. Memory foam can provide pressure relief, while innerspring and hybrid mattresses may offer more responsive support and airflow.

2. Firmness Level

Your preferred sleep position and body type can help determine the right firmness. Side sleepers often prefer a softer feel for pressure relief, while back and stomach sleepers may benefit from a medium-firm or firm mattress.

3. Support And Pressure Relief

Look for a mattress that supports your spine while cushioning pressure points such as your shoulders, hips and lower back. A supportive 12-inch mattress can provide enough comfort and structure for a range of sleepers.

4. Cooling Features

If you tend to sleep hot, consider a mattress with breathable covers, cooling materials or airflow-promoting designs. Hybrid and innerspring mattresses may offer added ventilation, while some foam mattresses feature temperature-regulating technology.
