What to look for in the best firm mattress for side sleepers

Choosing the right firm mattress can greatly enhance a side sleeper's comfort and sleep quality. Here are some considerations to keep in mind.

1. Support and Firmness Level

Side sleepers often need a mattress that provides excellent support to maintain spinal alignment. A medium-firm to firm mattress is usually the ideal choice, as it offers enough give to contour to the body's curves while still providing adequate support.

2. Material Type

Memory foam and latex mattresses can be great options for side sleepers, as they offer good pressure relief and contouring abilities. These materials help distribute the sleeper's weight evenly, reducing pressure points.

3. Thickness

A thicker mattress tends to provide better support and comfort for side sleepers, especially those who are heavier. Look for a mattress that is at least ten inches thick.

4. Edge Support

Good edge support can be beneficial for side sleepers, as it allows them to utilize the entire surface of the mattress without feeling like they're going to roll off.
