A Kmart cot mattress is a specially sized mattress designed to fit standard baby cots and nursery beds, providing a firm and supportive sleeping surface for newborns and toddlers. In simple terms, it’s the mattress that ensures your baby sleeps safely, comfortably, and in alignment with recommended safe sleep practices. The main reason Australians love Kmart cot mattresses is their combination of affordability, practicality, and availability — they offer good quality at a price that suits most families.
Here’s why a proper cot mattress matters: it supports a baby’s growing body, prevents unnecessary pressure points, and ensures airflow around the sleeping area, reducing the risk of overheating. Many parents choose Kmart mattresses for their durable construction, lightweight handling, and standard sizing, making them ideal for everyday nursery use.
Kmart offers a variety of cot mattresses to suit different baby needs, nursery spaces, and parent preferences:
High-density foam mattresses are lightweight, easy to handle, and provide firm, even support. Many come with breathable, removable covers, making cleaning simple and fast.
These feature gel-infused foam for extra comfort while maintaining firm support. The gel layer helps regulate temperature, ensuring babies stay cool during sleep.
Pocket springs or coil-based designs provide structured support and slightly more bounce. They are durable and maintain their shape over time, suitable for toddlers and older infants.
Tri-fold or roll-up mattresses are perfect for travel, grandparents’ houses, or temporary nursery setups. Lightweight and compact, they store easily when not in use.
Some Kmart cot mattresses have a firmer side for infants and a slightly softer side for toddlers, allowing the mattress to grow with your child.
All Kmart cot mattresses are sized to fit standard Australian cots (approximately 130 cm × 69 cm) to ensure a snug, safe fit.
Choosing the right cot mattress requires balancing safety, comfort, and practicality. Here’s an actionable guide:
Ensure the mattress fits your cot perfectly with no gaps around the edges. Gaps can pose a safety risk for infants.
Babies require a firm, flat surface for safe sleep. Foam or inner spring options are both acceptable, but memory foam should be firmer rather than soft.
Mattresses with breathable fabrics and moisture-wicking properties help regulate temperature and reduce the risk of overheating.
Removable, machine-washable covers are ideal for quick cleaning after spills or accidents.
Check that the mattress meets Australian safety standards, including fire retardancy and hypoallergenic materials where possible.
