Choosing the right cot mattress is essential for safety, comfort, and supporting your baby’s healthy development. This guide walks you through key factors to consider, along with mattress options from Boori that combine safety and quality.

Prioritise Safety and a Snug Fit
A cot mattress must fit the cot frame snugly with no gaps around the edges to prevent entrapment hazards. Always check the cot and mattress measurements before purchase and ensure they comply with recognised safety standards.
British safety standards are also rigorously met—both Boori cots and mattresses comply with BS EN 16890:2017
Opt for Firmness Over Plushness
For infants, a firm, flat mattress is crucial. It helps maintain open airways and supports developing bones. A mattress that is too soft can pose a suffocation risk, while a firm surface promotes safer sleep.
Whether pocket spring, foam, or hybrid with mesh, Boori’s options maintain firmness with supportive cores for healthy alignment.
Choosing the Right Mattress Type
Pocket Spring Mattresses
Pocket spring mattresses feature individually wrapped springs that respond to your baby’s movement for consistent support. They distribute weight evenly, helping to maintain healthy posture and comfort throughout the night.
Foam Mattresses
Foam options provide lightweight, firm support for newborns and young infants. Their simple construction makes them easy to handle and fit, while offering an affordable and safe sleeping surface.

Breathability and Temperature Regulation
Breathability is essential to keep your baby comfortable and to prevent moisture build-up. Mattresses with mesh panels, breathable covers or ventilated cores help regulate temperature, keeping the sleep surface cool and dry.
Durability and Hygiene
A cot mattress should be built to last, easy to clean, and resistant to spills. Many high-quality mattresses are designed for long-term use and may arrive compressed for delivery. Allow adequate time for them to expand fully before use.
Matching Accessories to Support Safety
Pair your mattress with fitted sheets and protectors designed specifically for its size. Avoid loose bedding, pillows, or soft toys in the cot for newborns to maintain a safe sleeping environment.
Final Thoughts
When selecting a cot mattress, focus on fit, firmness, breathability, and quality materials. Boori’s range of thoughtfully designed mattresses, from mesh hybrids to pocket springs, provide the support, ventilation, and safety your baby needs for restful sleep.
