  • Description

    The Silentnight Healthy Growth Miracoil Sprung Mattress is the perfect pairing of comfort and support. Your child should have a mattress that not only supports their sleep, but their body and wellbeing too.

    Silentnight's exclusive Miracoil springs create a supportive core and firm feel to benefit your child's growth and development. The springs have been intelligently zoned to provide more support to key areas such as the back, hips and joints.

    These springs are paired with an eco-friendly comfort layer of Eco Comfort Fibres™, a cooling, hypoallergenic comfort layer for a soothing night's sleep. The polyester fibres are spun from recycled plastic bottles, with each mattress saving them from ending up in landfill or our oceans. The springy nature of the material allows air to circulate and excess moisture to evaporate for a cleaner, fresher sleeping experience.

    Free from foam and chemical treatments, your child can get the healthy sleep they need. An attractive quilted cover finishes the mattress and secures the fillings, for years of high-performance use.

    The taped edges mean that the seams are reinforced and the mattress is single-sided so there's no need to turn it over. Simply rotate top-to-bottom fortnightly for the first 6 months, then monthly thereafter. This helps to to ensure there is even wear across the mattress surface.

    This mattress is covered by a 5 Year Guarantee for your peace of mind.

My daughter went straight off to sleep as if she were on her old one!
Having had this mattress before the original one was all white where as this one had grey side trims which I wasn’t so keen on. That however is me being very picky!
