Natural and safe sleep for your baby. 

The Obasan Crib Organic Mattress provides firm, breathable support for infants using only certified organic materials. The crib mattress comes with an organic wool protector included for an added layer of natural protection. Thoughtfully designed for safe sleep and handcrafted in Canada, it offers parents complete peace of mind.
Firm Infant Support : Designed to meet safe-sleep firmness recommendations for newborns and infants.
Made With Organic Materials : Handcrafted in Canada using GOTS- and GOLS-certified organic latex, cotton, wool, and coconut fibre.
Zero Off-Gassing : Made without synthetic foams, flame retardants, glues, or chemical treatments.

The Obasan Crib Organic Mattress is thoughtfully designed to support your baby’s earliest and most important stage of sleep.
With a level of firmness that remains appropriate from the newborn months through the toddler years, until they are ready to transition to a larger bed.

Handcrafted in Canada using certified organic materials, this mattress provides the firm support recommended for infants while allowing excellent airflow and natural temperature regulation. Its carefully layered construction promotes a safe, breathable sleep surface without the use of synthetic foams, chemical treatments, or flame retardants.

At the core, organic latex and coconut coir create a naturally firm and supportive base, while organic wool and cotton enhance breathability and moisture control.

Each crib mattress includes a GOTS-certified organic wool mattress protector that naturally repels moisture without plastics or synthetic barriers.

From the first night home through the toddler years, the Obasan Crib Organic Mattress delivers clean, chemical-free comfort you can trust.

Crib Base Requirements

Our crib mattress is designed to perform best on a firm, supportive base with built-in breathability using wooden slats.

A solid wood base with holes or vents for breathability is also a good option.

—

Wooden Slats

We recommend a slatted crib base with:

  • Metal or wooden slats spaced no more than 3” apart

Solid Wood Base

If your foundation has a solid wood surface, it must include ventilation for airflow. We recommend: 

  • Vent holes approximately 1” in diameter
  • Spaced about 12-15” apart

*** Please refer to our diagram in the product images for visuals.
