Designed to last

FIRMER for 0-12 months

Newborns and babies need firmer support; their bones are still soft, so it’s important they lie flat and straight – hence the firmer Baby side of our mattress.

SOFTER for 1-3 years

As babies grow into toddlers and their body shapes change, they need more responsive, cushioned comfort. Flip the mattress to the softer side, to ensure safe, comfortable sleep for toddlers up to 3 years.

For longer-lasting use

Double-sided tech

Our cot bed mattress is designed to provide the firm sleep surface recommended for new-borns, but thanks to our double-sided design it also offers growing toddlers the comfort and support they need too.

Comfort. For all ages

Simba Renew

Simba Renew is a soft, material offering superb comfort; it’s made from recycled fibres, gently combed into airy layers that allow plenty of airflow. We use three comfort layers of ingenious Simba Renew in our cot bed mattress – but in three different densities to achieve the correct levels of firmness for new-borns, babies, and toddlers.

Steady as they grow

The Aerocoil spring

Our patented Aerocoil springs are key to the Toddler side of our cot bed mattress. These individually pocketed, high carbon steel micro springs lie at the heart of Simba’s innovative tech; tiny enough to nestle unnoticed in the mattress, they’re designed to offer responsive support to your child’s changing, growing shape. They also allow fresh air to flow freely into and through the mattress.

Mattress expertise

In safer hands with Simba

Our cot bed mattress is certified to BS EN 16890, meeting all required safety regulations such as the correct flatness and firmness of the sleep surface, and the consistency of fit.

Your baby deserves a cleaner world.

A sustainable slumber

The cot bed mattress uses Simba Renew, a material made from recycled plastic fibres that are processed for softness, providing a gentle sleeping surface for your child.
