Is SnoozeShade like a hot car? Here's what the testing shows
A reassuring deep dive for parents worried about heat and airflow in prams
We hear it often: "Isn't it like a sauna under there?" or "That must be like locking a baby in a hot car." These phrases come from a very real and loving place - parents want to keep their babies safe. But the science, testing and real-world experience behind SnoozeShade tell a completely different story.
Why people worry - and where that fear comes from
The worry usually stems from social media posts showing muslins or blankets draped over prams, misleading thermometer tests placed on pram surfaces, and the use of dramatic words like "boiling", "furnace" or "sauna".
These concerns often refer to coverings that aren't made for airflow - like towels, blankets or muslins. SnoozeShade is different.
Hot car vs SnoozeShade - the facts
A sealed car is one of the most dangerous heat environments there is. Glass and metal absorb and amplify heat, there is no ventilation so hot air is trapped inside, sunlight heats surfaces which radiate heat into sealed air, and temperatures can rise 20 - 30°C quickly - even on a mild day.
Under SnoozeShade, the situation is fundamentally different. The EziBreez® mesh is air-permeable, meaning air flows in and out freely. It has been independently tested for CO₂ rebreathing safety. It does not trap gases or retain heat. It blocks 99% of UV rays. And prams are not sealed environments - air naturally circulates.
A sealed car traps and magnifies heat. SnoozeShade is air-permeable, ventilated and UV-blocking - the opposite of a furnace.
Real-world testing proves it
We ran the ultimate test. A pram was fully enclosed using SnoozeShade in full sleep mode and placed inside a sealed glass and metal office - replicating (as close as we could) the conditions of a parked car in summer.
The office temperature rose by over 10°C. Inside the pram? No significant temperature difference. This proves that SnoozeShade does not trap heat - even in extreme "hot car" conditions.
Thermometers, airflow and the fan effect
Parents sometimes use thermometers on pram mattresses. But this only measures the surface - not the air baby breathes. Pram bases can absorb heat from materials and metal framing, giving a false impression of interior temperature.
We measure where it matters: in the air space around baby's head. This gives accurate, consistent readings of ambient air - the kind your baby actually breathes in. That's what tells us if there's any dangerous heat build-up.
It's also why one of the most important tests we've passed is the CO₂ rebreathing test. This checks whether carbon dioxide - the air baby breathes out - can get trapped under the fabric. SnoozeShade passed with flying colours. And the science is simple: if carbon dioxide can escape, so can warm air. That means no heat build-up, no stuffiness and no risk of gases being trapped.
Fans can help too. Like standing in a warm room with a fan on, air movement increases comfort even if the temperature doesn't drop. That's why we recommend pram fans during very hot weather - paired with SnoozeShade for safe shade and airflow.
What SnoozeShade really does
SnoozeShade shields baby from up to 99% of harmful UV rays, allows air to circulate through its unique EziBreez® mesh, is tested to global safety standards including CO₂ rebreathing, and is designed for peace of mind even in warm conditions.
SnoozeShade is not a muslin. Not a blanket. Not a sauna. It's UV protection plus airflow - backed by science, loved by parents.
