Health Canada says:
Never leave a baby unattended in a cocoon or place the cocoon inside another product, such as a crib, cradle, bassinet or playpen.
Baby cocoons should never be placed on a regular bed, waterbed, air mattress, couch, futon, or chair. Placing a baby cocoon on a soft, uneven surface can increase the risk of suffocation.
To sleep safely, the baby must be lying on his back, alone in a crib, cradle or bassinet that complies with the regulations in force in Canada.
