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

An older 2015 study concluded that a medium-firm mattress may be the optimal choice for promoting sleep quality, comfort, and good spinal alignment. That said, it does not call out specific groups of people that may benefit from a medium-firm mattress.

A 2021 review agrees, showing that currently, scientific research concludes 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.

However, overall 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 will 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 layers aim to provide support, breathability, and comfort to targeted areas.

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

  • Price: Mattresses can be an expensive investment. People should decide which features to prioritize and buy a mattress that fits their budget.
  • Health: People living with a health condition, such as arthritis or chronic pain, may wish to look for mattresses that offer support to 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 can retain heat. However, many memory foam mattresses come with cooling layers or materials to counteract this.
  • Allergies: In some cases, mattresses can contain allergens such as wool or latex. People with allergies to these materials should check mattress specifications carefully and choose a hypoallergenic mattress.

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