Best Mattress for Pregnancy: A Doctor's Guide

Written by Dipti Mestry

Pregnancy can bring many wonderful changes, but it can also bring a few unexpected aches and pains.

As the body changes, many women experience back pain during pregnancy, hip discomfort, difficulty finding a comfortable sleeping position and disrupted sleep. Many pregnant women consult a physiotherapist like me when these changes begin affecting their comfort, movement and rest.

If you are experiencing discomfort, there is no need to panic. Many pregnancy-related aches are influenced by the physical and hormonal changes taking place in the body. Understanding what affects your sleep, and how your pillow & mattress can support you, can help ease some of your worry.

Common pregnancy sleep problems

As pregnancy progresses, getting comfortable at night can become increasingly difficult.

You may experience the following sleep disturbances:

• Lower back and hip discomfort
• Difficulty changing positions in bed
• Pressure around the hips and shoulders
• Feeling unusually warm while sleeping
• Frequent waking and pregnancy insomnia
• Difficulty finding a comfortable sleeping position

During pregnancy, changes in body weight, posture and sleeping habits can all influence how the body feels at night. This is where the right mattress for pregnant women and a supportive pillow can make a meaningful difference.

Can a bad mattress cause pregnancy back pain?

A mattress may not be the only cause of pain, but an unsuitable sleep surface can add to existing discomfort.

A mattress that is too soft may allow the body to sink excessively, while one that is too hard can create uncomfortable pressure around the hips and shoulders. When the body is already adapting to physical changes, an uncomfortable mattress may make it harder to find a supported sleeping position, diminishing the overall quality of rest.

The best mattress for pregnancy should strike a balance between comfort and support. It should allow pressure points to rest comfortably while helping the body feel stable and supported.

Firm or soft mattress during pregnancy?

One of the most common questions my patients ask me is: Should pregnant women sleep on a firm mattress?

There is no single answer for everyone. In most cases, an excessively firm mattress can create pressure around the hips and shoulders, particularly for side sleepers. A mattress that is too soft, however, may not provide the stability needed as the body changes.

The ideal choice is usually one that offers responsive support with comfortable pressure relief.

This is especially important when choosing a mattress for hip pain during pregnancy. If the hips are experiencing excessive pressure against the sleep surface, a mattress that provides some contouring and cushioning may improve comfort.

Why do I get hip pain while sleeping during pregnancy?

Hip pain during sleep can occur due to increased pressure on the hips when lying on your side, combined with changes in body weight and posture.

A comfortable mattress can help distribute pressure more evenly. A supportive pregnancy pillow can also help by supporting the legs and reducing strain around the hips and lower back.

However, a pregnancy pillow does not replace a good mattress. The mattress provides the foundation for whole-body support, while the pillow can help fine-tune your sleeping posture.

How should you sleep during pregnancy?

The best sleeping position during pregnancy can vary depending on the stage of pregnancy and individual comfort.

Side sleeping is commonly recommended as pregnancy progresses, and many women find that using a pregnancy pillow between the knees or along the body improves comfort and support.

If you have questions about whether it is safe to sleep on your back while pregnant, or which side you should sleep on during pregnancy, speak to your gynaecologist. Your individual health and stage of pregnancy should always be considered.

Why does a cooling, breathable mattress matter during pregnancy?

Many pregnant women experience increased warmth and may become hot sleepers.

A cooling mattress can therefore make a noticeable difference to sleep comfort. Look for a mattress designed with breathable materials and cooling technologies that help prevent the sleep surface from feeling excessively warm.

A cooler, more comfortable sleep environment may also be helpful when pregnancy discomfort is already causing frequent waking.

Do you need a new mattress when pregnant?

Not necessarily.

You do not need to replace your mattress simply because you are pregnant. But if your current mattress feels uncomfortable, creates excessive pressure, sags or no longer provides adequate support, pregnancy might make those issues more noticeable.

This becomes particularly important when looking for the best mattress for the third trimester, when changes in body size and sleeping positions can make comfort more challenging.

Our recommendations for pregnancy sleep comfort

Smart Luxe Pro SnowTec

A strong choice from The Sleep Company for pregnant women who tend to sleep warm. Its snowtec fabric can help create a more comfortable surface for hot sleepers, while its medium-soft responsive comfort & support help improve the quality of sleep.

Smart Ortho Royale

Every pregnancy is different

While the right mattress and pillow can improve sleep comfort, they cannot address every cause of pain or sleep disturbance.

Every pregnancy is different. Persistent, severe or unusual pain should always be discussed with your gynaecologist. They can provide guidance based on your individual health, specific symptoms and your stage of pregnancy.

The right mattress can be an important part of sleeping more comfortably for pregnant women. Combined with a supportive pregnancy pillow, a comfortable sleeping environment and medical guidance where required, it can help make nights more restful.

FAQs

What is the best mattress for pregnancy?

The best mattress for pregnancy provides a balance of support, pressure relief and comfort. The ideal firmness depends on your body, sleeping position and individual comfort requirements.

Should pregnant women sleep on a firm mattress?

Not necessarily. A mattress that is too firm can create pressure around the hips and shoulders, while one that is too soft may allow excessive sinking. Balanced, responsive support is generally more important than maximum firmness.

Does a pregnancy pillow replace a good mattress?

No. A pregnancy pillow can support specific areas such as the knees, hips and lower back, but the mattress remains the foundation for overall comfort and support.
