Frequently asked questions
How thick should a travel cot mattress be?
Most travel cot mattresses are 2-3 inches thick. Thicker options offer more comfort but may not fit all cots. Always check your cot's maximum mattress thickness to avoid safety gaps.
Are travel cot mattresses safe for infants?
Yes, if they are firm and fit snugly. Look for CertiPUR-US or Greenguard Gold certifications to avoid harmful chemicals. Avoid soft or pillow-top mattresses for infants under 12 months.
Can I use a regular crib mattress in a travel cot?
No, standard crib mattresses are usually too large. Travel cots require a foldable or custom-sized mattress that fits the compact frame.
How do I clean a travel cot mattress?
Most have removable, machine-washable covers. For foam stains, spot clean with mild soap and water. Avoid soaking the foam to prevent mold.
What is the best material for a travel cot mattress?
Foam is most common due to its light weight and ability to fold. Hybrid or gel foam options offer better cooling and support but are heavier. Choose based on your portability needs.
