Thrive Kids Trundle Support Foam mattress combines comfort, support, and practicality in a compact 10cm profile, making it ideal for trundle beds, bunk beds, or guest bedrooms. Crafted in the UK from high-density reflex foam (foam grade 30/105), it ensures your child’s weight is distributed evenly, promoting a comfortable and supportive night’s sleep. Designed with busy families in mind, hypoallergenic foam helps reduce exposure to allergens, making it suitable for allergy-sensitive children. Compact and convenient, the mattress arrives vacuum packed and rolled for easy transportation and handling. It fully expands within 72 hours of unpacking, providing a ready-to-use sleeping surface. As with all Viscotherapy mattresses, it is manufactured in the UK and conforms to all British Fire Regulations, ensuring both safety and peace of mind.
