Frequently asked questions
What certifications should I look for in a cot bed and mattress?
Look for CertiPUR-US (foam safety) and OEKO-TEX Standard 100 (no harmful substances). These ensure the mattress is free from toxins and meets rigorous safety standards, providing peace of mind for your baby.
How firm should a cot bed mattress be?
A firm mattress is recommended for infants to reduce the risk of SIDS. The mattress should not sag or conform to the baby's head. Most experts and safety standards advise a firm surface.
Is a cot bed worth buying over a standard cot?
Yes, cot beds are designed to grow with your child, converting from a cot to a toddler bed. This saves money in the long run and offers better value, as you won't need to buy a separate bed later.
How long can a baby use a cot bed and mattress?
Typically, from birth to around 4 years old, depending on the model. Most cot beds convert to toddler beds and have adjustable mattress heights to accommodate growing children.
What is the ideal trial period for a cot bed and mattress?
While many cot beds don't offer trial periods, a 30-day return policy is common for mattresses. For cot beds, focus on warranty length (usually 1-5 years) instead of a trial.
