After an energetic and stimulating day at school or at play, getting plenty of sleep is vital to a child’s emotional, cognitive and physical development. The bHealthy Active Plus Mattress has been specifically designed to boost your child’s development by helping them to get to sleep faster and for longer.

The bHealthy kids Active Plus mattress gives your child even more superior luxury and support as well as an even deeper supportive core, 25% more naturally cooling Medical Grade™ Foam and a deeper, cosy, quilted cover to help them reach their full potential. To top it off, the Active Plus mattress cover is completely chemical treatment free*!

Due to safety regulations and the increased depth of 18cm on this product, we do not recommend you purchase this mattress to use in conjunction with High/Mid Sleeper beds or for the top bunk of Bunk Beds.

*This applies to the mattress cover only.
