When sourcing Moses Baskets, the material choice is paramount for safety and durability. You should prioritize natural fibers such as hand-woven palm leaf, maize leaf, or organic wicker. Ensure the materials are free from toxic dyes, lead, and phthalates. For the interior, the mattress must be firm, flat, and covered with a waterproof but breathable material to meet SIDS (Sudden Infant Death Syndrome) prevention guidelines. Always verify that the weaving is tight and smooth to prevent any sharp protrusions that could injure an infant.
