Baby Mattresses 70x140 cm

A 70x140 cm baby mattress supports your child through an exciting stage of growth, offering extra space and lasting comfort as they transition from a baby's cot to a toddler bed. Commonly used with convertible and toddler beds, this mattress size provides the ideal balance of support and freedom of movement. At My Little Room, we carefully select quality mattresses designed to create a healthy, comfortable sleeping environment that grows with your child.

As little ones become more active and independent, their sleeping needs evolve too. A well-designed 70x140 cm mattress offers consistent support, breathable materials and long-lasting comfort, helping children enjoy restful nights while giving parents confidence in their choice.

The perfect size for convertible baby beds

A 70x140 cm mattress is the standard size for many convertible cots and toddler beds. Larger than a 60x120 cm mattress, it gives children more room to move while remaining perfectly suited to their early years. Before purchasing, it's always recommended to check your bed's internal dimensions to ensure the best possible fit.

Supporting the move to a toddler bed

Moving into a larger bed is an important milestone for many children. A supportive mattress helps make this transition more comfortable, encouraging restful sleep while giving little ones the confidence to enjoy their new sleeping space. The additional room also allows greater freedom of movement throughout the night.

Quality materials for everyday comfort

A comfortable sleep environment starts with carefully chosen materials. Our collection includes mattresses made from quality, breathable materials designed for everyday family life. Many models also feature recognised certifications, such as OEKO-TEX®, offering extra reassurance for parents.

Made to accompany growing children

A 70x140 cm mattress is designed to support children for several years. Durable construction, practical removable covers on selected models and lasting comfort make it an excellent choice for families looking for a mattress that keeps pace with everyday life.

Ready for the next stage

Once your child has outgrown a 70x140 cm mattress, many families choose a 90x190 cm or 90x200 cm mattress for their first full-size children's bed. Selecting a quality mattress today helps create a consistent sleep environment that evolves naturally with every stage of childhood.
