SINSWELL 4D Air Fiber Dual-Sided Baby & Toddler Mattress

Give your child the gift of a healthy, restorative sleep with the SINSWELL 4D Air Fiber Mattress. Engineered with advanced German material technology and a focus on pediatric ergonomics, this mattress provides the perfect balance of spinal support and high-performance breathability. Whether used in a nursery crib or as a portable mat for kindergarten, it offers a clean, safe, and supportive environment for growing bodies.

Key Benefits

Dual-Sided Ergonomic Support:** Designed for all developmental stages, this mattress features a dual-firmness core. The "Firm" side (Hs3) provides the necessary resistance for infant spinal alignment, while the "Soft" side (Hs5) offers cushioned comfort for older toddlers.

Advanced 4D Air Fiber Technology:** Utilizing a glue-free, intertwined fiber structure, the mattress allows for 95% air penetration. This "breathable core" prevents overheating and ensures a safer sleep environment, even for babies who have not yet mastered rolling over.

7A Antibacterial & Anti-Mite Protection:** The outer cover is crafted from Class A skin-friendly pure cotton treated with 7A-grade antibacterial technology. This creates a powerful barrier against allergens, mites, and bacteria, ensuring a hygienic surface for sensitive skin.

German-Engineered Core:** The internal structure is made from imported German Polypropylene (PP). This high-tech material is durable, resilient, and completely free of chemical adhesives and formaldehyde, meeting the strictest safety standards for infants.

100% Washable Hygiene:** Unlike traditional foam mattresses that trap moisture and odors, both the quilted cover and the 4D air fiber core are fully water-washable. This allows you to easily rinse away milk spills, sweat, or potty-training accidents.

How to Use

Place the mattress on a flat, stable bed frame or a clean kindergarten floor. For newborns and infants, ensure the Hs3 (Firm) side is facing up to support developing bone structures. For older children who prefer more pressure relief, the Hs5 (Soft) side can be used. The mattress is foldable and customizable, making it easy to transition between home and school environments.

Care & Safety

To maintain the highest level of hygiene, regularly unzip and remove the cotton cover for machine washing. The internal 4D fiber core should be rinsed under a showerhead or hose to remove deep-seated debris. Unlike traditional materials, this core is resistant to high temperatures and can be safely sun-dried to naturally disinfect and refresh the fibers.
