Choosing a mattress for a newborn baby is an important task that requires careful consideration. Babies spend most of their first few months of life sleeping, so having the right mattress can help your baby sleep more soundly. A firm mattress is essential to a newborn's growth and development while sleeping, as it provides the support needed for their soft bones and rapidly growing bodies. The mattress should also be flat and waterproof, and it must fit properly in the crib or cot, with no gaps that could trap the baby's head.

What You'll Learn

Firmness
When it comes to choosing a mattress for a newborn, one of the most important factors to consider is firmness. A firm mattress is crucial for a newborn's growth and development, and it also helps to ensure their safety during sleep.
Firstly, a newborn's bones are primarily made of soft cartilage that gradually hardens into bone. To support this process, a firm mattress provides the necessary support for their bones to develop properly. A firm surface also reduces the risk of sudden infant death syndrome (SIDS) by creating a safe sleeping environment. Soft mattresses may cause infants to sink into them, increasing the risk of suffocation. Therefore, a firm, flat mattress is recommended to prevent such incidents.
Additionally, newborns lack motor control in their early stages of development, so a firm mattress helps to keep them safely positioned in the centre of the mattress. This is further enhanced by features like border rods, which provide additional edge support to prevent compression near the edges.
When choosing a crib mattress, it's important to select one that fits snugly within the crib without any gaps or spaces around the edges. This prevents the baby from becoming trapped or suffocated between the mattress and the crib. The crib mattress should be at least 27.25 inches by 51.62 inches and no more than 6 inches thick to ensure a proper fit.
It's worth noting that your personal preference for mattress firmness may not align with what's best for a newborn. Newborns require firmer mattresses than adults and older children. If you opt for a foam crib mattress, choose a denser model. For innerspring crib mattresses, look for a steel gauge of 15.5 or below and a moderate-to-high coil count.
Dual-sided mattresses are also an option, offering a firm side for newborns and a softer side for when they transition to toddler beds. These mattresses provide years of use and are a cost-effective choice.

Safety certifications
When it comes to choosing a mattress for a newborn, safety is critical. A well-designed mattress reduces the risk of accidents and injuries during sleep, helping to promote safe sleep habits. Here are some key points to consider regarding safety certifications and standards for newborn mattresses:
Firmness and Flatness:
The mattress should be firm and flat. This is crucial for supporting your newborn's growth and development. A firm mattress provides the necessary back support for your baby and reduces the risk of Sudden Infant Death Syndrome (SIDS). It is also important to ensure the mattress fits snugly in the crib or bassinet without gaps to prevent the baby from getting trapped or suffocated.
Look for mattresses with safety certifications from reputable organizations. In the United States, the Consumer Product Safety Improvement Act of 2008 (CPSIA) regulates the interior dimensions of full-size crib mattresses. The Juvenile Products Manufacturers Association (JPMA) and the Consumer Product Safety Commission (CPSC) also offer safety certifications, ensuring the mattress meets specific guidelines and standards.
Waterproof and Washable:
A waterproof mattress or a washable mattress cover is highly recommended. This helps keep the mattress clean and hygienic, as it can be easily wiped down or washed in case of any messes or accidents.
Border Rods and Edge Support:
Look for mattresses that include border rods, which provide additional edge support. This feature helps to keep the mattress from compressing near the edges, ensuring your baby's safety and providing a more durable sleeping surface.
Organic and Non-Toxic Materials:
Opt for mattresses made with organic and non-toxic materials. While there may be no legal standard for organic mattresses, independent organizations can help guide you in choosing eco-friendly options. Some mattresses may be certified organic by reputable organizations, ensuring the use of quality materials.
Dual-Sided Mattresses:
Consider investing in a dual-sided mattress that can be used from the newborn stage through the toddler years. One side of the mattress can be firm, specifically designed for newborns and infants, while the other side can be softer, catering to a toddler's needs.
Always remember to follow safe sleep practices for newborns, such as placing them on their back to sleep and keeping the sleep area clear of any soft toys, loose bedding, or other objects that could pose a suffocation risk.

Breathability
When choosing a mattress for a newborn, breathability is a key consideration. A newborn baby spends most of their time sleeping, and a good crib mattress is essential for their health, safety, and overall well-being.
Firmness and Breathability
The mattress should be firm to provide the necessary support for a newborn's soft bones and developing spine. A firm, flat surface ensures the baby's safety and reduces the risk of sudden infant death syndrome (SIDS). However, it's important to note that the mattress should also be breathable. Newborns can regulate their body temperature through their face, so a breathable mattress is crucial to prevent overheating.
Materials and Certifications
Look for mattresses made with natural, organic materials that are hypoallergenic and breathable. The Saatva crib mattress, for example, contains natural, hypoallergenic latex, which is claimed to be more durable, buoyant, and breathable than foam. It also has a washable, organic cotton cover treated with an eco-friendly, water-repellent coating. Certifications like Organic Certified by Oregon Tilth, Made Safe Certified, and Greenguard Gold Certified can assure you of the mattress's quality and safety.
Waterproof and Washable
A waterproof mattress or a washable cover is essential to keep the mattress clean and hygienic. Look for a crib mattress with a waterproof cover, or consider using a waterproof mattress pad or protector. This will help protect the mattress from spit-up, diaper leaks, and other messes, ensuring a more sanitary sleep environment for your newborn.
Safety Considerations
In addition to breathability, there are other safety aspects to consider. Ensure the mattress fits snugly in the crib without any gaps or spaces to prevent the baby from getting trapped. Keep the mattress clear of pillows, toys, blankets, and other objects to reduce the risk of suffocation. A simple mattress with a firm, flat surface and a waterproof, breathable cover is ideal for a newborn's safe and comfortable sleep.

Washability
It is recommended to use a firm, flat, and waterproof mattress for newborns. The waterproof feature of the mattress helps to maintain a clean and dry sleep environment for the baby. Any spills or accidents can be easily wiped down, and the mattress can be kept sanitary and hygienic. This is especially important for the baby's health and safety, as a clean and dry mattress can help prevent the growth of bacteria and reduce the risk of allergies and other health issues.
Some mattresses come with a washable cover, which can be removed and cleaned separately. This allows for a more thorough cleaning of the mattress and can be especially useful in case of any messes or accidents. The HALO DreamWeave Crib mattress, for example, features a washable cover made from multiple layers of breathable quilted 3D mesh, providing a hygienic and comfortable sleep surface for the baby.
In addition to washability, it is crucial to consider the firmness of the mattress. A firm mattress provides the necessary support for a baby's growing body and developing bones. It helps to ensure the baby's health and safety by reducing the risk of suffocation, as a firm surface retains its shape and does not conform to an infant's head. This is in contrast to a soft mattress, which can indent and pose a risk of suffocation.
It is worth noting that the firmness preference for babies and adults differs significantly. While adults may prefer softer mattresses, a firm mattress is crucial for a newborn's proper growth and development. The baby's comfort and safety should always be prioritized when choosing a mattress.

Dual-sided
A newborn baby's bones are made of soft cartilage that eventually hardens into bone. During this process, a firm mattress provides the support they need for their bones to develop properly. A firm, flat surface also ensures your baby's safety by reducing the risk of suffocation.
The Saatva crib mattress is a dual-sided option that has received positive reviews from parents. It contains natural, hypoallergenic latex, which the brand claims is more durable, buoyant, and breathable than foam. The mattress also has a washable, organic cotton cover coated with an eco-friendly, water-repellent treatment. At $355, it is a more expensive option, but the lifetime warranty and free returns for up to 45 days may provide peace of mind for parents.
Another dual-sided option is the Serta Perfect Sleeper Cheery Days mattress, which offers both an infant and a toddler side at a more affordable price of under $100.
When choosing a dual-sided mattress, it is important to consider not only the firmness but also the materials used and the presence of safety certifications. Look for mattresses that are certified organic and made with natural materials, as these may be safer for your baby and the environment. Additionally, ensure that the mattress fits snugly within the crib without any gaps or spaces around the edges to prevent the baby from becoming trapped or suffocated.
