UMD: Mattresses with appropriate dimensions for use on beds in hospitals and nursing homes and/or for home care. These mattresses are usually filled with foam, include inner springs (e.g., wire coils), or are a combination of both; they are typically made of fire-retardant materials and are enclosed in waterproof antimicrobial covers. Some bed mattresses are designed to gatch in the typical positions of a hospital bed (e.g., Fowler). Bed mattresses made in an appropriate size for pediatric use or to support the weight of obese and morbidly obese patients (e.g., bariatric mattresses) are also available.
