Perfect for children's beds or guest rooms is the Kidman 10cm single memory foam mattress. Made with 1cm memory foam and 9cm reflex foam, this makes for a comfortable night sleep. It comes with a jacquard knitting cover and a non-slip bottom. This mattress is dust mite resistant, hypoallergenic, anti-bacterial and anti-fungal.. We recommend that this is a firm mattress, but comfort is subjective! The mattress depth makes it the perfect bunk bed mattress as most bunk beds require a mattress thickness of a maximum of 12.5cm.
