Abstract
Safety features for a crib mattress are described. One safety feature is designed to maintain airflow to a fan inlet despite the fan inlet being blocked by a mattress sheet. Another safety feature removes obstructions to airflow within the mattress so that air is dispersed more uniformly across the sleep surface which is formed by a taut sheet of fabric. Yet another safety feature is designed to help retain a fitted sheet on a mattress and make it difficult for the sheet to be inadvertently pulled off the mattress.
