Firmness for Side Sleepers
Side sleepers need a medium-firm mattress, usually rated 4 to 6 out of 10. This firmness allows the hips and shoulders to sink slightly into the foam. That sinkage aligns the spine and reduces pressure points. A mattress that is too firm can cause shoulder pain. Too soft can lead to poor spinal alignment.
Memory Foam Thickness
Thickness affects support and durability. Most budget memory foam mattresses range from 6 to 12 inches. For side sleepers, a thickness of at least 10 inches is recommended. Thinner mattresses may not provide enough cushioning for heavier individuals. Thicker foam layers also tend to last longer.
Density and Durability
Memory foam density is measured in pounds per cubic foot. Higher density foam, around 3 to 5 pounds, offers better support and longevity. Budget mattresses often use lower density foam, which can sag over time. Check the product specifications for density information. Owner reviews can also reveal durability issues.
Cooling Features
Memory foam retains heat, which can be uncomfortable for some sleepers. Look for gel-infused foam, open-cell technology, or breathable covers. These features help dissipate body heat. Cooling is especially important for side sleepers who may have more contact with the mattress. Some budget models include these features without a high price.
