Frequently asked questions
What certifications should a hypoallergenic cot mattress have?
Look for GREENGUARD Gold (low chemical emissions), OEKO-TEX Standard 100 (no harmful substances), and CertiPUR-US (for foams). These ensure the mattress is free from many allergens and irritants.
Are latex mattresses safe for babies with latex allergies?
If your baby has a latex allergy, avoid natural latex. Instead, choose mattresses made from organic cotton, food-grade polyethylene, or CertiPUR-US foams. Always check the materials list.
How often should I clean a hypoallergenic cot mattress?
Wash the mattress cover at least monthly in hot water to kill dust mites. Spot-clean any stains immediately. Some covers are waterproof, which helps prevent mold and mildew.
Can I use a mattress topper on a hypoallergenic cot mattress?
It's generally not recommended, as toppers can create a soft sleeping surface, increasing suffocation risk. Choose a mattress that already offers the desired comfort and hypoallergenic properties.
What is the difference between a cot mattress and a crib mattress?
Cot and crib mattresses are often used interchangeably, but cots (UK term) may have slightly different dimensions. Always check your cot's size to ensure a snug fit. Most standard crib mattresses work for cot beds.
