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 sleeping in it.
  • Targeted support: Some people may prefer mattresses with 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. When choosing a mattress, a person should consider if they have any back, hip, or shoulder pain.
  • 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 are comfortable temperatures is important when a person is working to improve their sleep quality or duration. Many mattresses contain 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.

Few studies have investigated the long-term effects of different types of mattresses. Partly, this is due to variations in mattress structure, materials, and proprietary technology, which create difficulties for scientists to draw accurate comparisons across products.

A 2021 systematic review of 39 studies investigated which type of mattress promoted comfort, sleep quality, and spinal alignment. The researchers classified the different mattress types according to firmness, rating them as “soft,” “medium-firm,” or “extra-firm.” They concluded that a medium-firm mattress can help to alleviate low back pain and improve sleep quality in people with non-specific low back pain.

However, the type of mattress a person chooses will vary based on preference. Some people may prefer a soft, sinkable mattress that contours their body, helping to alleviate joint and muscle pain. A soft mattress may also benefit light sleepers who find it difficult to fall asleep on a firmer mattress.

Ideally, people should choose a mattress with a free trial period to see how it feels before committing to it.

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 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 with 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 contain a variety of materials, including:

Mattress brands typically include three or more layers in their soft mattress models. However, each brand of mattress will include different materials in different thicknesses. As such, a person may wish to trial their chosen mattress at home or try it out in a store to see if it suits their needs.

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

Who might benefit from a soft mattress?

Soft mattresses may best suit those with a lower body mass index (BMI). A lighter person will place less pressure on a mattress, and the reduced pressure may prove more comfortable.

People with a higher BMI may benefit from a firmer mattress that keeps the spine in a neutral alignment while preventing them from sinking into the mattress.

Can a soft mattress help reduce pain?

An older 2012 study found that people with arthritis are more likely to experience disturbed sleep and insomnia. Anecdotally, a soft mattress may help to alleviate pressure on the joints, helping to relieve arthritis pain. However, the mattress should provide enough support to keep the spine in a neutral alignment.

Is a soft mattress good for a particular sleep position?

Some mattress brands specify that their soft mattresses are best for side sleepers, as they provide low resistance and gentle support.

When purchasing a new mattress, a person should look for products offering a trial period or should try the mattress out in-store to see whether it suits their preferred sleep position.

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. Likewise, research does not 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 could worsen sciatica symptoms for some people.

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 people with sciatica, as it helps to prevent the sciatic nerve from becoming compressed, irritated, and inflamed.

Learn more about the best mattresses for sciatica.

Are soft mattresses better than firm?

Soft mattresses are not necessarily better than firm. A 2015 article reports that a medium-firm mattress can provide better comfort and sleep quality. However, some people may find a medium-firm mattress too firm.

Are soft mattresses good for older adults?

Older adults may be more susceptible to joint pain, so may need a mattress that helps to alleviate this symptom. A soft mattress may provide more comfort, but a firmer mattress may provide better support.

A 2021 systematic review investigated the effect of different mattress types on back pain and sleep quality. According to the review, a medium-firm mattress is the most comfortable option for people with low back pain.

Similarly, a 2015 study found that sleeping on a medium-firm mattress led to a reduction in musculoskeletal pain, and an improvement in sleep quality.

Learn about the best mattresses for seniors here.

Sleep is important for maintaining overall health and well-being. 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 consider, such as back pain. Soft mattresses may not be suitable for people who sleep on their backs or stomach. Additionally, heavier people may not find soft mattresses comfortable. However, soft mattresses may be suitable for pressure point relief.

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 has concerns about sleep or experiences back pain that will not go away, they should consult a healthcare professional for advice.
