Baby Mattresses

Natural and organic baby mattresses are designed to give infants and toddlers a firm, breathable, and truly low-toxic sleep surface. By combining certified organic cotton, natural wool, and hand-tufted craftsmanship, these crib mattresses support proper spinal alignment, help regulate temperature, and minimize exposure to synthetic foams, chemical flame retardants, and harsh adhesives.

In this collection, you will find both Natural and Organic options built with our signature Japanese-style craftsmanship. Unlike conventional soft foam pads, these are handmade baby mattresses (approx. 3.5" thick) layered and compressed to provide the essential firmness recommended by pediatricians for infant safety. Whether you choose a pure cotton core or a wool-blend for moisture control, these mattresses offer a flat, stable foundation that allows your baby to breathe easier and sleep cooler.

The same standards used in our Organic Mattresses and Natural Futon Mattresses carry through to this crib line. We simply scale down our premium adult construction methods to ensure your child rests on materials chosen for purity, durability, and gentle support, giving you peace of mind that their sleep environment is as clean as your own.

Creating a safe, practical crib setup also means protecting the mattress without sealing it under plastic. We recommend pairing your baby mattress with a breathable, waterproof Crib Mattress Protector made from natural materials. This helps block spills and nighttime leaks while still allowing air to circulate. As children grow into the toddler stage, you can add a soft Natural Mattress Pad for a touch of extra comfort without compromising support.

To finish the crib, choose fitted sheets and bedding that are as gentle as the mattress itself. Lightweight Organic Cotton Bed Sheets and carefully chosen Natural Bedding help wick moisture and reduce overheating. The result is a sleep environment that feels calm, breathable, and thoughtfully coordinated from the inside out.

Organic Cotton and Foam Japanese-Style Baby Mattress - Comfort Pure

Designed for Safe Sleep Standards

When it comes to infant sleep, safety is the priority. Sleep experts and safety guidelines agree that a firm, flat surface is essential for supporting growing bones and ensuring a clear airway. Our cotton crib mattresses are constructed using high-tension compression to create a dense, flat surface that does not sag or conform around the baby’s face. At 3.5 inches thick, they provide the structural integrity needed for a safe sleep environment, meeting the firmness standards crucial for newborns and toddlers alike.

Breathable & Chemical-Free

Synthetic waterproof mattresses can trap heat, leading to uncomfortable sleep. Our wool crib mattresses utilize the natural breathability of cotton and wool to wick away moisture and circulate air, helping to regulate your baby's temperature naturally. Most importantly, we use natural wool as a fire barrier, eliminating the need for the flame retardant chemicals often found in standard polyurethane foam mattresses. This creates a pure, non-toxic baby mattress that supports a cleaner, healthier nursery.

Essential Protection for Natural Fibers

Unlike synthetic mattresses wrapped in non-breathable vinyl, our natural cotton mattresses are porous to maximize airflow. To maintain hygiene without blocking this breathability, it is vital to pair your mattress with a high-quality organic waterproof crib mattress protector or a heavy wool moisture pad. These protectors shield the pure cotton core from inevitable leaks and spills, ensuring your non-toxic baby mattress remains clean, dry, and mold-free for the duration of its use.

Frequently Asked Questions: Baby Mattresses

Why is this mattress so firm?

Firmness is a critical safety feature. Soft surfaces are not recommended for infants. Our organic crib mattresses are handmade and compressed to create a dense, flat foundation that aligns with safe sleep guidelines, supporting your baby's developing spine without sagging.

Is the mattress waterproof?

No. Because we use natural cotton and wool to maximize breathability, the mattress itself is porous. We strongly recommend pairing this mattress with an organic waterproof mattress protector or a wool moisture pad. This protects the core from diaper leaks while maintaining airflow.

Does it fit a standard crib?

Yes. Our mattresses are designed to fit standard full-size cribs (roughly 28" x 52"). However, because they are handmade, slight variations can occur. The 3.5" profile is safe and ensures there are no dangerous gaps between the mattress and the crib rails.

Are there flame retardants in this mattress?

Absolutely not. We use natural wool as the fire barrier. Wool is naturally flame-resistant and allows us to meet federal flammability standards without using chemical sprays, borate powder, or fiberglass barriers commonly found in cheaper baby cot mattresses.

What is the difference between "Natural" and "Organic"?

Both options use the same safe, non-toxic materials (cotton and wool). The Organic collection uses certified organic cotton and wool, ensuring the fibers were grown without pesticides. The Natural collection uses high-quality, unbleached, untreated cotton and natural wool that is clean and safe but lacks the official paper certification, offering a lower price point.

Can I flip this mattress?

Yes. We recommend flipping and rotating the mattress every time you change the sheets. This helps the natural cotton fibers compress evenly and extends the life of the mattress, ensuring it stays flat and supportive through the toddler years.
