Buyer’s Guide

Welcome to the Cot Mattress Buyer’s Guide! Here, you’ll find essential information and helpful advice on choosing the right cot mattress for your baby. Our guide covers everything from key features and considerations to general tips for a comfortable and safe sleep experience for your little one.

Important Features to Consider When Buying a Cot Mattress

When shopping for a cot mattress, there are several key aspects to take into account. These include the mattress’s mattress size, firmness, breathability, and waterproof features. Let’s dive into each of these features in more detail to help you make an informed decision when purchasing a cot mattress.

Mattress Size

Cot mattresses come in different sizes to fit various cot models. The most common cot mattress sizes are 140 cm x 70 cm, 160 cm x 70 cm, and 175 cm x 75 cm. Measure the dimensions of your cot before purchasing a mattress to ensure a proper fit and safety. Remember that the mattress should fit snugly into the cot without leaving gaps, where your baby could become trapped.


A firm cot mattress is essential for your baby’s safety and comfort. Look for a mattress made from high-density foam or a firm, tightly woven fabric. A soft or saggy mattress can pose a risk of suffocation. To test the firmness of a cot mattress, gently press your finger into the surface. The mattress should feel firm and not sink significantly under your pressure.


Breathability is crucial for a cot mattress, as it helps regulate your baby’s body temperature and reduces the risk of overheating. Look for a mattress with air holes or natural materials such as cotton, wool, or latex. These materials help promote airflow and moisture wicking, ensuring your baby stays comfortable and dry during sleep.


What details are available on the materials used in baby crib mattresses?

The type of materials utilized for creating baby crib mattresses can differ according to the specific product. Despite this, common materials include cotton, wool, and latex. These substances are renowned for their breathability, hypoallergenic properties, and capacity to offer comfort and support for infants and toddlers. Prior to making a purchase, always verify the product label to discover the specific material in the baby crib mattress you’re interested in.

When selecting the perfect material for baby crib mattresses, it is crucial to consider factors like breathability, hypoallergenic properties, and support. This will ensure a cozy and secure sleeping environment for your little one. Some materials might be more hypoallergenic or environmentally friendly than others, which could be an important consideration for certain parents.

What is the appropriate age range for a baby to use a baby crib mattress?

A baby crib mattress is typically suitable for babies up to the age of 2. This guideline, however, is flexible and can differ based on the individual child’s development and requirements. As children grow and become more active, they may need a different type of mattress designed for their specific stage of development, such as a toddler bed mattress or a flat mattress for a crib.

Parents must carefully monitor their child’s progress and needs to determine the ideal time to transition to a different type of mattress. It is essential to select a mattress that will provide the appropriate support and comfort for their growing child’s needs and preferences throughout the various stages of development.

How do firm and soft baby crib mattresses differ?

The main distinction between a firm and a soft baby crib mattress lies in the level of support they provide. A firm mattress offers more support, which can be beneficial for infants and toddlers with certain medical conditions or who sleep on their stomachs. On the contrary, a soft mattress, while slightly less supportive, may be more comfortable for some infants.

Parents should also consider their baby’s weight, as well as their personal preferences and needs, when choosing between a firm or soft baby crib mattress. Moreover, ensure that the mattress is suitable for the recommended age range, as some brands may advise a more firm or softer option depending on the baby’s development and age.

How frequently should a baby crib mattress be cleaned or replaced?

A baby crib mattress should be cleaned regularly, at least once a week, to maintain its hygiene and prevent the accumulation of dust, germs, and stains. Always adhere to the manufacturer’s cleaning instructions to ensure the mattress remains in good condition and provides suitable support over time. Additionally, consider rotating the mattress so that your baby does not always sleep in the same spot, promoting even wear and extending its lifespan.

The frequency of replacing a baby crib mattress depends on various factors like condition, age, and material. Generally, it is recommended to replace a baby crib mattress every 6 to 12 months or when it no longer offers the necessary comfort and support. As children outgrow baby crib mattresses, parents may need to transition to a toddler bed or flat-sheet mattress designed specifically for that stage of development.

What is the better choice for a baby: an organic or non-organic baby crib mattress?

The preference between an organic and a non-organic baby crib mattress will depend on your specific needs and preferences. Organic cotton mattresses are generally hypoallergenic, eco-friendly, and free from harmful chemicals, making them a popular choice for parents seeking a healthier, sustainable option for their baby.

Non-organic baby crib mattresses, on the other hand, may be made from synthetic materials and chemicals, which may raise potential health and environmental concerns. However, there are high-quality, non-organic baby crib mattresses available on the market that still offer excellent support and comfort for infants.

Can baby crib mattresses be used during travel with infants?

Yes, baby crib mattresses can typically be used during travel with infants. They can be easily transported and set up in various sleeping spaces, making them convenient for parents. When traveling frequently, consider investing in a lightweight, portable and washable baby crib mattress, which will make it easier to maintain and clean during your travels. Some baby crib mattresses may also come with a carrying case, further facilitating their transport and storage. Always consult the manufacturer’s instructions for proper care before packing for your trip.
