The incredible Simba Hybrid® Cot Bed Mattress features two children's mattresses in one - on one side of this dual-sided mattress is a firmer surface for newborns and babies, while the other side is softer for toddlers. Not only does this increase the longevity of the mattress, letting you use it for much longer than most other kid's mattresses, but it ensures that your child gets the best support possible as they grow.

The recommended firmness for your child's age

Babies require a firmer sleeping surface as their bones are still soft, so one side of this innovative cot bed mattress features a thick layer of firm Simba Renew™ material. This incredibly breathable layer ensures the recommended flat, firm surface for babies up to 12 months old.

A water resistant inner lining prevents moisture and nighttime accidents getting inside the mattress, ensuring the durability and shape retention of the mattress is protected.

Simply flip over when your child reaches one

Once your little one is over 12 months old, you can flip this ingenious mattress over to the toddler bed side. From the age of 1-3, children need more responsive, cushioned support, which is exactly what the toddler side of the Simba Hybrid® Cot Bed Mattress provides.

A responsive Aerocoil® Spring layer provides targeted support and pressure relief to their growing bones and joints, guiding them through their growth and development during the night. Two layers of Simba Renew™ - one medium to firm and one softer and more sumptuous - enhances core support alongside cloud-like comfort. Just the sleep your little one deserves.

This side also features the practical water-resistant lining, and the entire mattress is finished in a soft, breathable knitted outer layer. This cover is also hypoallergenic for a fresher sleeping environment and removable for machine washing.
