The Ingravity Kids Tetrix multi-stage kids mattress is the best solution on the market for the transition from cot to adult bed. Designed to meet the precise sleep needs of children from 18 months to 14–15 years of age, this mattress features two distinct growth-stage faces whose materials adapt to the specific physiological characteristics of each phase of childhood development.
Side A is designed for younger children (ages 2 to 8) and features a profiled DryFeel micro-spring foam upholstery with maximum breathability, which adapts to every part of the child's body for correct spinal alignment and continuous airflow throughout the night. Reinforced lateral safety barriers — made from high-density ergonomic foam — keep younger sleepers safely in the central sleeping area, preventing rolling towards the edges.
Side B, intended for children from age 8 onwards, features Respirel® memory foam upholstery — the most breathable memory foam on the market — combined with the high-density Fisiocell® foam core, providing a medium-firm feel with outstanding spinal support and an exceptionally fresh, hygienic sleep environment.
The cover is 100% washable and split into two independent parts via a next-generation divisible zip system, making it easy to remove and wash each section separately — even while continuing to use the mattress on the other side. Side A is made from 3D mesh fabric for maximum breathability and freshness, while Side B uses the exclusive Ingravity Kids Clean&Dry Stretch fabric with hydrophobic and anti-stain treatment, preventing liquids and odours from penetrating the inner layers. All materials carry the Oeko-Tex® 100 Class 1 certification — the most stringent safety standard for children's textiles. Made in Spain, with free shipping across mainland Spain and the Balearic Islands.

Lateral reinforcement
This mattress has two high-firm foam blocks on the sides of the 'little sleeper' area, which means that the little ones always sleep in the central area of the mattress, reducing the risk of them approaching the ends of the bed and falling out of it.
DryFeel® Micro Springs
The 'little sleeper' face is incorporated into the core DryFeel foam with maximum breathability, shaped in the form of micro springs, which provide adequate firmness to each part of the body, while contributing to greater ease of air circulation inside the mattress.
Respirel memory foam
This is the most breathable memory foam on the market. Its gem-like structure facilitates the free entry and exit of air inside the mattress, while providing great adaptability and comfort when lying down.
Ingravity® kids Water-Repellent Anti-Stain Fabric
Fabric with water-repellent and anti-stain treatment, with maximum softness and elastic knit, which promotes perfect breathability of the inner layers of the mattress, while protecting the inner layers of the mattress from the penetration of liquids and stains. It is machine washable and its treatment does not disappear with washing.
