Natural Cotton and Wool Japanese-Style Firm Baby Mattress

Give your baby a safe, firm, and naturally comfortable place to sleep with this handcrafted cotton and wool crib mattress. Made in the USA using untreated green cotton and natural New Zealand lambswool, it offers a breathable, chemical-free sleep surface. The wool layer provides natural temperature regulation and serves as a built-in fire barrier—meaning no doctor's prescription is required. Encased in durable cotton twill and hand-tufted, this mattress offers pure comfort and peace of mind.

This mattress is available in two distinct firmness levels to suit your child's developmental stage:

• Crib Mattress (Newborns & Infants): Rated Very Firm. This mattress is densely packed with extra layers of cotton and wool to provide a flat, supportive surface that meets safety recommendations for reducing the risk of SIDS.
• Toddler Mattress (12 Months+): Rated Semi-Firm. Designed for children over 1 year old, this version uses fewer layers of filling to offer a softer, more comfortable feel while still providing healthy support.

Note regarding fit: These mattresses are intentionally handcrafted to 28" x 54" to ensure a snug fit in standard cribs, reducing gaps that could pose a safety risk.
