Choosing a nursery mattress for your baby is an important decision one that supports your baby’s sleep, night after night.
Before anything else, always check the size of your cot or sleep space.
At CuddleCo, we offer:
A well-fitting mattress should sit snugly inside the cot, with no gaps around the edges. Taking a moment to double-check measurements ensures a safe and supportive sleep environment from day one.
Understanding the Different Types of Cot Mattresses
When browsing nursery mattresses, you’ll usually come across three main types. Each offers slightly different support and comfort levels.
A foam cot mattress is lightweight, supportive and practical.
-
Often easier to lift when changing sheets
-
Offers consistent, firm support
-
A great everyday option for many families
Foam mattresses are particularly convenient during those early months when sheets need frequent changing.
Pocket sprung mattresses contain individual springs housed in fabric pockets.
-
Springs move independently
-
Respond to your baby’s movement
-
Provide more tailored support
This type of cot mattress is often chosen by parents looking for enhanced comfort and long-term durability as their baby grows into toddlerhood.
You may also see coir pocket sprung mattresses, which combine natural coir fibres (derived from coconut husk) with pocket springs. Coir adds breathable, firmer support - offering a more natural feel while maintaining structure.
An open spring (sometimes called Bonnell spring) cot mattress uses a traditional interconnected spring system.
-
Structured, evenly distributed support
-
A durable, supportive option
-
Often a balanced middle ground between foam and pocket sprung
What’s the Difference?
In simple terms:
-
Foam – Lightweight, practical and supportive.
-
Open spring – Traditional, structured and durable.
-
Pocket sprung (including coir options) – More responsive, with individualised support and enhanced breathability.
The right choice often comes down to personal preference, budget and how long you’d like the mattress to support your child.
Materials Matter: What to Look For
Beyond the core structure, the outer materials play an important role too.
Hypoallergenic Bamboo Fabric
Many of our mattresses feature bamboo fabric covers, which naturally offer:
-
Hypoallergenic properties
-
Breathability
-
Moisture-wicking comfort
Bamboo helps create a fresher, more hygienic sleep surface, something many parents find reassuring during the early months.
Waterproof Training Layer
Some designs also include a reversible side with an easy-clean waterproof training layer.
This can be especially helpful during:
-
Early potty training
-
Night-time accidents
-
Transitional stages
Instead of needing an additional protector, the mattress itself offers practical support, making everyday life that little bit simpler.
A Thoughtful Choice for Better Sleep
Choosing the right cot mattress is about finding the balance between safety, comfort and practicality.
-
Check your measurements.
-
Consider the level of support you’d prefer.
-
Look for breathable, hypoallergenic materials that work for your home.
