Frequently asked questions
Are hexagon mattresses safe for infants?
Yes, when they are firm, flat, and fit snugly in the playpen. Look for CertiPUR-US and OEKO-TEX certifications to ensure no harmful chemicals. Always follow safe sleep guidelines: no pillows, blankets, or bumpers.
How do I clean a hexagon playpen mattress?
Most have removable, machine-washable covers. For spot cleaning, use mild soap and water. Avoid soaking the foam; air dry fully before use. Always check the care label.
What firmness is best for a playpen mattress?
A firm mattress is recommended for infants to reduce SIDS risk. For toddlers, medium-firm may be acceptable. Test by pressing: the mattress should not compress more than a few millimeters.
Do hexagon mattresses fit all playpens?
No, they are designed specifically for hexagon-shaped playpens. Measure your playpen interior and compare with product dimensions. Most standard hexagon models from major brands will fit.
How long do hexagon playpen mattresses last?
With proper care, they typically last 2-3 years. Signs of wear include sagging, loss of firmness, or visible damage. Replace if the mattress no longer provides a flat, firm surface.
