People looking for a balance of support and comfort may find a medium-firm mattress suitable.

A 2021 review showed that a medium-firm mattress is best for comfort, alignment, and sleep quality. The authors wrote that this firmness may be best for people with nonspecific low back pain.

A small study exploring the relationship between body type and the best mattress for quality sleep found that people with a higher body weight had a more neutral spine alignment on a firmer mattress. In contrast, lighter-weight individuals had a more neutral spine alignment on a softer mattress. This study may indicate that a medium-firm mattress might be a suitable choice for people of moderate weight.

However, there is limited scientific research on the best mattress firmness for different sleeping positions.

The basic construction types for medium-firm mattresses include:

  • Foam: Foam mattresses can include polyurethane foam, memory foam — which is more durable and is denser and closely cradles the body — and latex, a more responsive foam option.
  • Innerspring: Innerspring mattresses are an older type. They have a coil support system that can use individually wrapped or fully connected coil springs. There may be a fabric or foam layer on top of the springs for comfort.
  • Hybrid: Hybrid mattresses combine multiple layers of polyurethane or memory foam with coils. The distribution of the coils, padding, and thickness of the foam aim to provide support, breathability, and comfort to targeted areas.

Considering the following factors can help a person choose the best medium-firm mattress:

  • Health: People living with a health condition, such as arthritis or chronic pain, may wish to look for mattresses that keep the spine and hips aligned and relieve pressure on the joints.
  • Sleep temperature: People who tend to sleep hot or live in warm climates may want to avoid memory foam mattresses because they may retain heat. However, some memory foam mattresses have cooling layers or materials to counteract this.
  • Allergies: Some mattresses may contain allergens such as wool or latex. People with allergies to these materials may want to check mattress specifications carefully and choose a hypoallergenic option.
  • Motion isolation: People who wake easily or share a bed with people with different sleeping habits may prefer a mattress that limits movement transfer from one side to the other.
  • Pressure relief: People, especially those who sleep on their side, may consider a mattress with pressure-relieving properties. Some companies design mattresses to distribute a person’s body weight across a larger area. These options may provide extra cushioning for common pressure points, such as the shoulders and hips. They may also feature additional support in other areas to promote healthy alignment.
  • Edge support: Edge support makes getting in and out of the bed easier and safer. Many brands include reinforced foam edges to make the mattress more stable.

Below, we answer the top frequently asked questions about medium-firm mattresses.

Mattress firmness is a personal preference, and whether a medium or firm mattress is best for a person will depend on several factors. These include their body weight, shape, sleeping style, and any health conditions, such as chronic pain, arthritis, or insomnia.

A firm mattress may be better for people who sleep on their front or back, as it may support the body and keep the spine aligned. They may also be easier to get in and out of for people who find this difficult due to age or a health condition.

A medium-firm mattress will offer more cushioning and may suit those who sleep on their side. It may offer a more even balance between comfort and support.

People can use sleep trials to test their mattresses before making their final decision.

People can sleep on their side on a medium-firm mattress. Many brands selling medium-firm mattresses state their products are suitable for side sleepers. However, individuals may want to test if their mattress provides enough pressure relief on their shoulders and hips.

A medium-firm mattress has a middling level of firmness that balances comfort and support. This firmness level may keep a person’s spine aligned while they sleep. It may suit the full range of common sleep positions: side, back, and combination.

Medium-firm mattresses may suit most sleep styles. Some scientific research shows that they may improve sleep quality and spinal alignment.

With memory foam and hybrid options available for various budgets, many people may find medium-firm mattresses suitable for their needs.
