Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If allergies or chemical treatments are on your mind, this mattress makes a strong case. It's hypoallergenic and free from foam and FR chemical treatments, and the odour-resistant core is washable, which matters a great deal at the leaky-nappy stage. The firm feel gives the flat, supportive surface recommended for young children, and the EcoComfort Fibres™ in the cover help with airflow, so warm sleepers should stay a little more comfortable. At £109 in cot bed size, stocked by 3 retailers, it sits at an accessible price point without skimping on the reassurances that count: a 60-night trial to change your mind and a 5-year guarantee behind it.
Key Features & what's inside
- Outer fabric. A breathable, lightweight outer fabric with cooling EcoComfort Fibres™. In practice, that means better airflow around your toddler and less overheating through the night.
- Core. A firm polyester core that is breathable, odour resistant and washable. The firmness gives the even support growing children need, and being able to wash it is a genuine help after accidents.

Who's it NOT for?
This is a cot bed mattress only, so it won't suit older children moving to a single bed. It contains no springs or foam comfort layers, and at 10cm deep it's a simple, firm design: fine for toddlers, but not a long-term option once your child outgrows the cot bed.
Silentnight Healthy Growth Cosy Toddler Mattress
Is the Silentnight Healthy Growth toddler mattress washable?
The polyester core is washable and odour resistant, according to Silentnight's own product page. That makes it practical for the inevitable accidents of the toddler years, as you can clean the mattress itself rather than relying on a protector alone.
How firm is the Silentnight Healthy Growth Cosy Toddler Mattress?
Silentnight describes it as firm. That's the right feel for this age group, as a firm, flat surface supports growing bodies evenly. It may feel harder than an adult mattress, but that's by design rather than a drawback.
Does the Silentnight toddler mattress come with a trial or guarantee?
Yes. Silentnight offers a 60-night trial and a 5-year guarantee on this mattress, so you have time to see how your child settles on it and cover if anything goes wrong.
Is the Healthy Growth toddler mattress suitable for children with allergies?
It's hypoallergenic and naturally resistant to allergens, and it's free from foam and FR chemical treatments. Across the mattresses we cover, that combination is a sensible choice for allergy-prone children, though always speak to your GP about specific allergies.
What sizes does the Silentnight Healthy Growth toddler mattress come in?
It's available in Cot Bed size only, at a depth of 10cm, priced at £109. If your child has already moved to a single bed, you'll need to look at a different model.
