Frequently asked questions
Why choose a cot bed with a mattress included?
It ensures a perfect fit and safety compliance, saving you the hassle of finding a compatible mattress. The mattress is designed specifically for the cot bed, reducing gaps that could pose risks.
What certifications should I look for?
CertiPUR-US certifies foam is free from harmful chemicals, while OEKO-TEX Standard 100 ensures materials are tested for harmful substances. Greenguard Gold indicates low chemical emissions for better indoor air quality.
How firm should the mattress be for a newborn?
A firm mattress is vital for safety, reducing the risk of Sudden Infant Death Syndrome (SIDS). The mattress should not compress significantly under the baby's weight and should fit snugly in the cot.
Can a cot bed mattress be used in other cots?
Usually not, as cot bed mattresses are sized specifically for their frame. Using in another cot may leave gaps or not fit properly, compromising safety. It's best to keep the mattress with its original cot.
What is the average lifespan of a cot bed mattress?
Most cot bed mattresses last 2-4 years, depending on quality and usage. The mattress should be replaced if it shows sagging, tears, or no longer fits securely in the cot bed frame.
The verdict
For overall quality and eco-friendliness, the Silver Cross Beckham Cot Bed with Mattress stands out. For value without compromise, pick the Babyletto Hudson 3-in-1. If your baby runs warm, the Boori Ellie with its pocket spring mattress offers excellent cooling.
