Background: Children with neurodisabilities, including those with intellectual and developmental disabilities (IDD), autism and other complex needs, frequently experience sleep disturbances, impacting their health, behaviour and caregiver well-being. This study evaluates the effectiveness of Cubby Beds, sensory safety beds designed to improve sleep quality and safety for children with neurodisabilities. Methods: A survey of 225 caregivers assessed changes before and after Cubby Bed adoption using multiple-choice and Likert-scale questions. A Wilcoxon signed-rank test was used to analyse key outcomes. Results: Caregivers reported significant improvements in sleep duration (median increase from 4-6 to 8-10 h per night, p < 0.001) and reductions in self-injurious behaviours, minor injuries and elopement incidents (p < 0.001). Effects on medical procedures, seizures and life-threatening events were mixed. Conclusions: Findings suggest Cubby Beds enhance sleep and safety for children with neurodisability. Further research is needed to assess long-term impacts and integration into healthcare strategies.
