9 Best Cot Mattresses for Baby’s Beds

Best Cot Mattresses for Baby’s Beds

What is a good quality cot mattress? The answer depends entirely on what you are looking for on the market.

When it comes to babies, comfort and safety, are the two most important considerations. You can’t take chances with your baby’s wellbeing.

For starters, never buy a refurbished product. This is the advice most paediatricians in the UK would give you.

Research into cot death or SIDS indicates that babies sleeping on refurbished beds are at a higher risk of SIDS.

You might be tempted to reuse your firstborn’s cot mattress with your second born. Well, such thoughts are ill-advised.
So, a new baby mattress is in order, and here are the 10 leading products we have selected for you.

What to Look for in a Cot Mattress

Because your baby will likely be spending more than twelve hours on the bed, you will want to ensure the mattress you choose is not only comfortable and safe but also high quality.

Here are the major pointers that can help you choose a comfortable and safe choice.

Type of Cot Mattress

There are two main types of cot beds: foam and innerspring. Usually, an innerspring mattress tends to be heavier than a foam bed and will last longer and maintain its shape better.

Innerspring also offer good support and bounce. When shopping for an innerspring crib mattress, we urge you to choose one with a higher coil count.

A foam cot bed made weighs less than an innerspring bed. If you choose to buy a foam mattress, make sure you look for one with a high foam density.

High-density foam means more support and safety for your baby. Always avoid mattresses that tend to produce any form of off-gassing.

Size of Cot Mattress

You can’t just pick any cot bed size and expect it to fit in your baby’s cot. Two major sizes are standard in the UK:

  • UK Large Cot Size – 140 by 70 Centimetres
  • UK Standard Cot – 120 by 60 Centimetres

You have to be specific concerning the aforementioned sizes. Otherwise, you may end up choosing a mattress that is slightly larger or smaller than your cot.

Firmness & Airflow

It does not matter which type of baby mattress you buy, just make sure you choose one that will provide your baby with the ideal firmness.

We insist on ideal firmness because soft cot mattresses are highly associated with cot death. A sinking bed could easily obstruct the airways of your little one.

You can easily test the firmness of a given mattress by pressing the middle of the bed with your index finger. A good quality mattress for a baby should not indent easily.

You also need a mattress with superior aeration. This is particularly important when shopping for memory foam baby mattresses.

Choose a foam bed that is air permeable and breathable. There should be enough airflow to allow your baby to sleep cool for the long hours he or she will be in bed.

Apart from firmness and airflow, also make sure the bed contours properly with your baby’s body to avoid pressure points.


Always buy a new cot mattress for each baby, preferably with spring pockets rather than foam, to last for an older child.

It is best if the bed has a removable, breathable, machine washable cover that can always be refreshed to improve the health of your baby.

Make sure the bed you are about to buy is comfortable, practical, and lightweight while providing firm and lasting support.

Always be extremely selective as far as the materials are concerned. Eco-friendly materials are most recommended to help your baby avoid SIDS or any other complications.
