Comfy and great for my little boy. Not as thick as I was expecting and if you are slightly heavier then maybe not the best. Gabrielle. Willerby Hull, GB. Tue Dec 16 2025

Our slimmest mattress, made for the lowest bed frames — a great choice for a child's first proper mattress in bunk beds, cabin beds and mid-sleepers. Visco-elastic memory foam moulds to your child's shape, supporting the spine and neck while dispersing weight evenly to ease pressure at the shoulders, hips and lower back. Its open-cell structure lets air circulate freely, and the foam is dust mite and mildew resistant. Delivered rolled and boxed. Once unwrapped, allow 48–72 hours in a well-heated, well-ventilated room for the mattress to expand to full size and for the initial foam odour to clear. General information: Manufacturer's 1 year guarantee.

Bought it as a bed topper. Very happy with the purchased. Delivered on time. Yaku. Cork, Ireland. Tue Jan 21 2025

A little extra depth for a first grown-up bed — ideal for teenage girls moving on from a bunk or cabin frame, while still fitting compact frames comfortably. Visco-elastic memory foam moulds to your shape, supporting the spine and neck while dispersing weight evenly to ease pressure at the shoulders, hips and lower back. A firmer layer beneath holds you level, which matters while you're still growing. Delivered rolled and boxed. Once unwrapped, allow 48–72 hours in a well-heated, well-ventilated room for the mattress to expand to full size and for the initial foam odour to clear.
