Baby Sprung Mattresses for Cots & Cot Beds

A sprung cot mattress uses supportive springs to ensure sturdiness and airflow. In general, it is produced in cot (120x60cm) and cot bed (140x70cm) sizes to offer a safe, comfortable sleep for babies. If you’re choosing your baby's very first mattress or replacing one that no longer fits as your baby has outgrown, sprung and pocket sprung models can be a great option. 

What is a Sprung Cot Mattress?

A sprung cot mattress has a core made of metal springs, which is wrapped in layers of padding and a cover. The springs lend the mattress its firmness and allow air pass. Hence, it prevents your baby’s body heat from building up on it during sleep, thereby reducing the risk of overheating.

Sprung cot mattresses are classified into 2 main types. 

• Standard sprung mattress

It incorporates one connected spring unit across the whole surface. 

• Pocket sprung mattress

It relies on individual springs, which are encased into its own fabric pocket. 

Since the springs move separately, a pocket sprung mattress adjusts more thoroughly to your baby’s weight and shape. Thus, this promotes more balanced support across the entire surface.

Also, both mattress types are naturally breathable compared with solid foam. For this reason, many parents prefer them for the cots and cot beds of their babies.

Cot vs Cot Bed Sizes (120x60 & 140x70)

Cot and cot bed mattresses differ in size. Then, choosing the right dimensions is as important as the mattress type.

A standard cot mattress measures 120 x 60 cm, such as CuddleCo’s mattress, designed for use from the moment your baby is born.

A cot bed mattress measures 140 x 70 cm, such as Mollydoo’s mattress, sized for a cot bed that converts into a junior or toddler bed later on. Due to the small variations between brands, the internal measurements of your own cot or cot bed before ordering is what you should check before ordering.

A well-fitting mattress should sit tightly against all 4 sides of the frame, leaving no spaces for your baby’s arm, leg or head to slip into. For a quick check, if you can fit more than 2 fingers between the mattress and the frame, the mattress is the wrong size.

A Comparison of Sprung, Fibre and Foam Mattresses

Sprung and pocket sprung mattresses are firm and breathable, with good airflow and long-term support. Fibre mattresses are made from layers of polyester or natural fibre padding, so they’re lighter and often more affordable. On the other hand, foam mattresses are the lightest of the three and easy to handle when changing sheets. However, this option doesn’t offer the same airflow as a sprung core.

Additionally, many sprung and pocket sprung mattresses feature a hypoallergenic or anti-allergy cover. Some of them include bamboo or coir layers for extra breathability, as well. If certain allergies are common among family members, it’s better to look for the details on the product page before buying one.

Safe Sleep: Choosing a Firm, Well-Fitting Mattress

No matter which types you choose, the principles for a safe sleep apply similarly. A baby’s mattress should be firm and completely flat, and it should be well-fitting, leaving no gaps around the edges.

To check the firmness quickly, you should press the mattress with your hand. Meanwhile, it shouldn’t sink more than a few millimetres. Also, it’s wiser to replace mattresses that are sagging, sagging, or no longer lie flat. 

As a parent who provides your baby with a sense of security during bedtime, you can also fully enjoy watching your precious one be comfortable and content.
