Getting the right amount of good quality sleep each day is essential for a person’s health and well-being.

The Centers for Disease Control and Prevention (CDC) recommends that adults aim for the following amount of sleep per night:

  • 18–60 years: 7 hours

  • going to bed at the same time each night to maintain consistency
  • ensuring the bedroom is dark, quiet, and at a comfortable temperature
  • finishing meals 2–3 hours before sleeping

Another factor that can help a person sleep well is their sleeping environment, including their mattress choice. When selecting a mattress, a person may consider the following:

  • size
  • support
  • comfort
  • durability
  • construction
  • warranty and trial periods

Research into the benefits or risks of sleeping on a soft mattress is limited. One review found that a self-adjusted medium-firm mattress may provide optimal sleep comfort and spinal alignment.

However, individual preferences and health needs may play a role in whether a soft mattress is beneficial to sleep quality. Researching and testing different mattresses can help people decide whether a soft mattress will suit them. Many mattress brands offer trial periods so that a person can test their chosen mattress and return it or exchange it if needed.

A person looking for a soft mattress may consider some of the following points:

  • Size: A person should consider whether their chosen mattress will fit their bedframe, whether it will be high or low enough to get in and out of comfortably, and whether it will be big enough to accommodate everyone who will be sleeping in it.
  • Targeted support: Some people may prefer mattresses that have different levels of support in different areas of the mattress, for instance, more support in the middle of the mattress to keep the lower back aligned. Other people may prefer softer support in these areas to relieve pressure on the hips. A person should consider any back, hip, or shoulder pain they may have when choosing a mattress.
  • Cost: Some mattresses can be expensive. A person should consider the features they need in a mattress and how that will suit their budget.
  • Motion isolation: Some may find motion isolation important if they typically sleep with another person in the bed.
  • Sleep temperature: Making sure the room and bed is a comfortable temperature for sleep is important when a person is working to improve their sleep quality or duration. Many mattresses are built with cooling foam or topper materials to draw heat away from a person’s body and increase airflow through the mattress. If a person feels that foam mattresses will be too hot to sleep on, they may wish to consider other types of mattresses, such as innerspring mattresses or those filled with other materials, such as wool.

A person can research the best type of mattress for their needs by reading reviews online, comparing products, and testing mattresses out in stores or by using the sleep trials many companies offer.

However, those with pain or other health conditions may wish to discuss their needs with a doctor before committing to a purchase to get advice on what kind of mattress may be best for them.

If a person is worried about their sleep quality, or they have developed back pain, hip pain, or shoulder pain, they should talk to a doctor for advice.

Below are some of the most frequently asked questions about soft mattresses.

What are the different kinds of soft mattresses?

Soft mattresses can be made with a variety of materials, including:

Mattress brands will typically include three or more layers in their soft mattress models. Soft mattresses are also often made in the full range of sizes, from twin to California king.

However, a person may wish to trial their chosen mattress at home or try it out in a store to see whether the softness feels adequately comfortable and supportive, as each brand will include different materials in different thicknesses.

A person with a latex allergy should avoid soft latex mattresses.

Who might benefit from a soft mattress?

Those with a lower BMI may benefit from a soft mattress. A lower body weight places less pressure on the surface of the mattress and the softness will absorb the weight from common pressure points such as the hips and shoulders.

Heavier people may benefit more from a firmer mattress as it will keep the spine in a neutral alignment and prevent a person from sinking into the mattress.

Can a soft mattress help reduce pain?

A 2011 study found that people with arthritis are more likely to have disturbed sleep and insomnia. A soft mattress may provide some relief to those with arthritis and other conditions that affect the joints. The soft materials can relieve pressure on the joints. However, the mattress should be supportive and keep a person’s spine in a neutral alignment.

Is a soft mattress good for a particular sleep position?

Some mattress brands specify that its soft mattresses are best for side sleepers as they provide low resistance and gentle support. A person should trial their chosen mattress or try out different models in stores to find out how it will feel for their preferred sleep position.

People with health conditions to consider, such as back pain, may benefit more from a more supportive, firmer mattress that will keep the spine aligned. For instance, older 2003 research that suggests a medium-firm mattress is better for people with lower back pain.

Learn more about the best sleep positions for back pain.

Can a soft bed cause sciatica?

There is no research to suggest that a soft mattress can cause sciatica, and research does not clearly indicate whether people with sciatica or nerve pain should use a soft, medium, or firm mattress.

However, sleeping on a mattress that does not offer adequate support or pressure relief may make a person’s symptoms worse.

A 2015 systematic review reports that medium-firm mattresses and models with custom inflation can provide better sleep comfort, quality, and spinal alignment. Keeping the spine aligned is important for those with sciatica to prevent the sciatic nerve from becoming irritated, compressed, or inflamed.

Sleep is important for maintaining a person’s overall health and well-being. Having a comfortable mattress that provides a good balance of comfort and support can help a person improve their sleep quality and duration.

When choosing the best soft mattress, a person should consider their individual preferences and any health considerations they have to take into account, such as back pain. Soft mattresses may not be suitable for people who sleep on their back or stomach. Additionally, heavier people may not find soft mattresses comfortable. However, soft mattresses may be suitable for people who need relief for pressure points.

Many mattress brands offer sleep trials of 100 nights or more so a person can test their chosen mattress and exchange it if necessary.

If a person is worried about their sleep or experiences back pain that will not go away, they should consult a healthcare professional for advice.
