Children spend even more time sleeping than adults, making their mattress an important investment for healthy development. A good kids' mattress needs to be supportive enough for growing bodies, comfortable enough for restful sleep, and practical enough to handle the inevitable spills and accidents. We have reviewed the best options available on Amazon UK.
Support: Children's spines are still developing, so a medium-firm mattress is generally recommended. Avoid very soft mattresses that allow the body to sink in too far.
Size: A standard single (90cm x 190cm) works from toddler age right through to the teenage years. Some parents opt for a small single (75cm x 190cm) for younger children in smaller rooms.
Waterproofing: For younger children, a waterproof cover or removable washable cover is invaluable. Some mattresses come with a waterproof layer built in, saving you from needing a separate mattress protector.
Hypoallergenic materials: Children can be more sensitive to dust mites and allergens. Look for hypoallergenic foam or anti-allergy treated covers.
Both can work well for children. Foam mattresses are lighter (easier for changing sheets), quieter, and good at absorbing movement. Spring mattresses offer more airflow and a bouncier feel that some children prefer.
For bunk beds or cabin beds, a thinner foam mattress (15-18cm) is usually safer and more practical than a thick spring mattress, as it keeps the sleeping surface further below the guard rail.
Most children transition from a cot to a toddler bed between 18 months and 3 years. The standard cot mattress size is 60cm x 120cm or 70cm x 140cm. When your child outgrows the cot (or starts climbing out), it is time to move to a single mattress.
Many parents use a toddler bed with a small single mattress (75cm x 190cm) as an interim step, before moving to a standard single bed frame.
A medium to medium-firm mattress is best for children. Too soft can affect spinal development, while too firm can be uncomfortable. For very young children (under 3), a firmer mattress is recommended for safety reasons.
A good kids' single mattress costs between £60 and £150. There is no need to spend as much as you would on an adult mattress, as children are lighter and the mattress will likely be replaced as they grow.
Not necessarily. While memory foam offers good comfort, a standard foam or pocket spring mattress is perfectly adequate for most children. Memory foam can also sleep warmer, which may not suit children who tend to overheat.
