What Size is a Junior Mattress? 

A junior mattress provides the ideal sleeping solution for children moving on from a cot. Measuring 70 cm, or 27.5 inches, in width, this size provides space and security to little ones that find a single bed too large for their sleeping needs.

When it comes to buying a bed for a child, many people opt for a single bed. Others, though, prefer to purchase a junior bed as this provides the child with more space than a cot but is still small enough to offer security and comfort.

A good night’s sleep is vital for health and wellbeing, and having a restful sleep will help towards your child’s development and growth. However, it is not just a secure and sturdy bed that is important – you also need to ensure you invest in a good mattress. Junior mattresses are ideal for children and at BedSOS, we have the perfect options at competitive prices.

Getting a good sleep is essential for children as it helps support their growth and the development of their bones. It also ensures that they are able to concentrate and focus during the day as they will be well rested and healthy.
