Description

Your little one does most of their growing at night, so it's hugely important that their mattress encourages healthy development. The Simba Hybrid® Kids Mattress does this and more, offering unparalleled support to their growing body, as well as plush comfort that will get them excited for bedtime.

Orthopaedic spinal support for growing bones

A layer of innovative Aerocoil® Microsprings provide intense orthopaedic support with a medium firm feel. This is the ideal tension for healthy bone development, keeping your child's spine properly aligned and posture controlled as they grow. These springs adapt to their movements throughout the night, tailoring support to their pressure points as they move.

Beneath this incredible support layer is a blanket of spring-comfort high definition foam. This, working alongside the rigid foam support base, contours to the natural curvature of your little one's body, applying gentle pressure relief to their joints. Edge support ensures they stay supported no matter how they wriggle in the night, offering orthopaedic support right to the very edge of their bed.

Cooling, breathable memory foam that cradles your little one in comfort

Above the innovative microspring support unit is a layer of cooling, open-cell foam infused with graphite to naturally reduce overheating, keeping your child at the optimal sleeping temperature. This foam also cradles them in comfort, complementing the pressure relieving qualities of the Aerocoil® springs.

A super soft, breathable sleep surface encourages airflow throughout the entire Simba Hybrid® Kids Mattress, enhancing the hypoallergenic properties of mattress and encouraging a cleaner, more hygienic sleeping environment.

Features

Aerocoil® Microsprings

Small, cone-shaped titanium springs that provide precise, tailored support as you move.

Graphite Infused Simbatex® Cooling Foam

Infused with cooling graphite for a science-based, refreshing night’s sleep.

16cm Depth

This mattress is approximately 16cm deep.

Knitted Cover

This luxurious soft knitted cover is breathable, which helps to keep the sleeper at an even temperature all night long.

Orthopaedic Support

Designed to offer a firmer sleep surface, providing targeted support for your back and joints.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

No Need To Turn

A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.

Vacuum Packed & Rolled

Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully over time, usually being comfortable enough to sleep on after 48 hours.

Pressure Relieving

This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.

Hypoallergenic

Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.

Vegan Friendly

This product is made from materials that are 100% free from animal by-products.

Zoned CertiPur® Foam Base

Specific support zones target your body's pressure points for precise pressure relief and posture control.

Made in the UK

This item has been manufactured in the UK.

Fire Resistant - Low Hazard
