As an expert in the sleep niche, we’re here to guide you through the essential considerations for choosing the perfect mattress during this pivotal period.

Factors Affecting the Decision For Buying Mattress for Pregnancy:

Below are the main factors when buying a mattress for pregnancy:

1. Optimal Firmness Level

One of the key factors to consider when selecting a mattress during pregnancy is firmness. Generally, a medium-firm mattress is recommended. This firmness level provides a balanced combination of support and comfort, which is crucial as your body undergoes significant changes.

A mattress that is too soft may cause your body to sink excessively, leading to misalignment of the spine.

On the other hand, a mattress that is too firm can create uncomfortable pressure points, particularly around the hips and shoulders.

A medium-firm mattress supports the body adequately while offering enough cushioning to relieve pressure points.

2. Ideal Mattress Materials

The material of the mattress plays a significant role in comfort and support. Here are some top recommendations:

  • Memory Foam: Memory foam mattresses are excellent for pressure relief. They conform to the body’s shape, providing targeted support to areas like the hips, shoulders, and lower back, which are under increased pressure during pregnancy.
  • Latex: Latex mattresses are hypoallergenic and offer a responsive surface that supports easy movement. They are also known for their durability and temperature regulation properties, making them ideal for pregnant women who experience temperature fluctuations.
  • Hybrid: Hybrid mattresses combine the support of innerspring coils with the comfort of foam or latex. This type of mattress provides sturdy support and excellent pressure relief, catering to varying needs during pregnancy.

3. Cooling Features

Pregnancy can often lead to increased body temperature, causing discomfort during sleep. Therefore, it’s essential to choose a mattress with cooling features.

Look for mattresses with gel-infused foam or breathable materials that promote airflow and help regulate temperature. This will help prevent overheating and ensure a cooler, more comfortable sleep environment.

4. Edge Support

Good edge support is vital for pregnant women, as they often need to sit on the edge of the bed when getting in and out.

A mattress with reinforced edges provides stability and prevents sagging, making it easier and safer to maneuver​.

5. Motion Isolation

With the frequent need to move or get up during the night, motion isolation becomes an important feature.

A mattress that minimizes motion transfer ensures that you do not disturb your partner with your movements and vice versa.

Memory foam and hybrid mattresses are particularly effective in this regard, allowing for undisturbed sleep.

6. Health and Safety

When selecting a mattress during pregnancy, it’s crucial to ensure it is free from harmful chemicals and allergens.

Look for certifications such as CertiPUR-US or Oeko-Tex, which indicate that the mattress meets safety standards for low VOC emissions and is free from toxic substances.

This ensures a healthier sleeping environment for both the mother and the unborn baby.

7. Trial Period and Warranty

Given that comfort is subjective and varies from person to person, it’s wise to choose a mattress that offers a generous trial period, ideally at least 90 nights.

This allows you to test the mattress in the comfort of your home and ensure it meets your needs. Additionally, a good warranty (10 years or more) is a testament to the manufacturer’s confidence in their product and provides peace of mind.

How Pregnancy Impacts Your Sleep?

Pregnancy can significantly impact a woman’s sleep due to a variety of physiological, hormonal, and psychological changes. Here’s an overview of how pregnancy affects sleep, based on multiple sources:

1. Hormonal Changes

Progesterone Levels: Increased levels of progesterone during pregnancy can have a sedative effect, making some women feel more fatigued during the day.

However, this hormone can also contribute to sleep disturbances by causing an increased need to urinate at night (nocturia) and by relaxing the muscles, leading to issues such as sleep apnea.

2. Physical Discomfort

As the pregnancy progresses, the growing belly can make it difficult to find a comfortable sleeping position. This is especially pronounced in the third trimester, where lying on the back can compress major blood vessels and lying on the stomach becomes impossible.

Many pregnant women experience back pain due to the extra weight and changes in posture. This can make it challenging to sleep comfortably.

3. Increased Urination

The increased blood flow and the growing uterus pressing on the bladder can lead to frequent urination, causing interruptions in sleep throughout the night.

4. Restless Legs Syndrome (RLS)

Many pregnant women report experiencing restless legs syndrome, which causes an uncontrollable urge to move the legs, especially at night. This can significantly disrupt sleep.

Most of the women undergo RLS in the third trimester, impacting the overall sleep during this phase. Hashmi et al. made this observation when analyzing the rationales for reduced sleep during pregnancy.

John Hopkins Medicine has regarded RLS to be one of the major problems that pregnant women can face.

5. Heartburn and Gastroesophageal Reflux Disease (GERD)

The relaxation of the lower esophageal sphincter due to increased progesterone can lead to heartburn and acid reflux, particularly when lying down, making it difficult to sleep comfortably.

When lying down gravity does not help keep the acid down, thus it transfers back to the esophagus.

6. Sleep Apnea

Weight gain and increased neck circumference during pregnancy can exacerbate obstructive sleep apnea, where breathing repeatedly stops and starts during sleep.

7. Anxiety and Stress

Pregnancy can bring about anxiety and stress related to impending motherhood, health concerns, and other factors. These emotional changes can lead to insomnia and poor sleep quality.

Coping Strategies to Reduce Disturbances:

To manage these sleep disturbances, pregnant women can try several strategies:

  • Sleep Positioning: Sleeping on the left side with a pillow between the legs can improve circulation and reduce discomfort. John D. Jacobson, MD, Department of Obstetrics and Gynecology, Loma Linda University School of Medicine believes that sleeping on your left can be beneficial as it improves blood circulation as well. However, you can shift to the right side occasionally.
  • Routine: Maintaining a consistent sleep routine can help regulate the body’s internal clock.
  • Hydration and Diet: Limiting fluids in the evening and avoiding spicy or acidic foods can reduce nocturia and heartburn.
  • Exercise: Regular, moderate exercise can help alleviate symptoms of RLS and improve overall sleep quality.
  • Relaxation Techniques: Practices such as prenatal yoga, meditation, and deep breathing exercises can help reduce anxiety and promote better sleep.

Understanding these impacts and implementing coping strategies can help pregnant women achieve better sleep, which is crucial for their health and the health of their developing baby.

Best Pregnancy Sleep Positions:

Finding the best sleep positions during pregnancy is crucial for comfort and health. Here are some of the most recommended positions, along with their benefits and tips for achieving them:

1. Sleeping on the Left Side (SOS):


  • Improves Blood Flow: Sleeping on the left side increases blood flow to the heart, kidneys, and uterus, providing optimal oxygen and nutrient delivery to the fetus.
  • Reduces Swelling: This position helps reduce swelling by improving circulation and decreasing pressure on the inferior vena cava, a major blood vessel that returns blood from the lower body to the heart.


  • Use a pregnancy pillow to support your back and place another pillow between your knees to align your hips and reduce strain on your lower back.
  • Try to keep your legs and knees bent, which can also help with comfort and alignment.

2. Using Pillows for Support:


  • Strategically placing pillows can help alleviate pressure points and provide support to various parts of the body.
  • Supporting your belly with a small pillow can reduce strain on your back and help prevent hip and lower back pain.


  • Place a pillow under your belly for support.
  • Use a pillow behind your back to prevent rolling over onto your back during the night.
  • A full-length body pillow can offer comprehensive support for your entire body.

3. Avoiding Certain Positions:

  • Back Sleeping: In the second and third trimesters, sleeping on your back can compress the inferior vena cava and decrease blood flow to the fetus, potentially causing dizziness, shortness of breath, and low blood pressure.
  • Stomach Sleeping: As your belly grows, this position becomes impractical and uncomfortable.

4. Alternative Positions for Relief


  • Sometimes alternating positions or slightly modifying your usual sleep position can provide relief from aches and discomfort.


  • If heartburn is a problem, try sleeping in a semi-upright position using a wedge pillow or several pillows to prop up your upper body.
  • Lying on your back with a pillow under one side of your back to tilt your body slightly can relieve pressure from your back while still improving circulation.


Why is choosing the right mattress important during pregnancy?

Selecting the right mattress during pregnancy is crucial for ensuring proper support and comfort. Pregnancy can bring about various physical discomforts like back pain, hip pain, and increased pressure on joints, making it essential to have a mattress that alleviates these issues.

What features should I look for in a mattress during pregnancy?

Opt for a mattress that provides adequate support to your body, especially to the lower back and hips. Look for options with medium to medium-firm firmness, as they tend to offer a good balance of support and comfort. Additionally, consider mattresses with motion isolation to minimize disturbances from your partner's movements.

Are memory foam mattresses suitable for pregnancy?

Memory foam mattresses can be suitable for pregnancy, especially if they offer proper support and conform to your body's contours without sinking too deeply. However, some individuals may find memory foam mattresses to retain heat, so consider options with cooling features if you tend to sleep hot.

Should I choose a mattress with adjustable firmness settings?

Adjustable firmness settings can be beneficial during pregnancy, allowing you to customize the firmness level according to your changing needs and preferences as your pregnancy progresses. However, ensure that the mattress provides adequate support in all firmness settings.

Can a mattress affect pregnancy-related sleep issues?

Yes, the right mattress can help alleviate common pregnancy-related sleep issues such as back pain, hip pain, and discomfort due to pressure points. A supportive and comfortable mattress can promote better sleep quality and overall well-being during pregnancy.

How do I know if a mattress is suitable for pregnancy?

Test the mattress in-store if possible, paying attention to how it supports your body and whether it relieves pressure points. Look for mattresses with certifications for durability and safety, and consider factors like warranty and return policies to ensure satisfaction with your purchase.

Are there any specific mattress types to avoid during pregnancy?

Avoid mattresses that are overly soft or lack sufficient support, as they may exacerbate back pain and discomfort. Additionally, mattresses with strong odors or chemical off-gassing should be avoided, as they may cause sensitivity issues during pregnancy.

Can a mattress affect pregnancy-related conditions such as edema or acid reflux?

While a mattress alone may not entirely alleviate conditions like edema or acid reflux, choosing a supportive mattress can help reduce discomfort associated with these conditions. Elevating the upper body slightly with pillows or an adjustable bed frame may further help alleviate symptoms like acid reflux.

Should I consider purchasing a pregnancy pillow along with a mattress?

Pregnancy pillows can complement the support provided by a mattress by offering additional cushioning and alignment for your body. Consider using a pregnancy pillow to support your growing belly, relieve pressure on your hips, and maintain proper spinal alignment while sleeping.

How often should I replace my mattress during pregnancy?

If your current mattress is old or showing signs of wear, consider replacing it before or during pregnancy to ensure optimal support and comfort. Generally, mattresses should be replaced every 7-10 years, but pregnant individuals may need to replace their mattresses sooner if they no longer provide adequate support.


Selecting the right mattress during pregnancy is crucial for ensuring restful and comfortable sleep.

By considering factors such as firmness, material, cooling features, edge support, motion isolation, and health and safety standards, you can find a mattress that caters to your specific needs during this transformative time.

Investing in a quality mattress not only enhances your sleep quality but also contributes to your overall health and well-being during pregnancy.
