Abstract: A section of Velcro material is positioned on the edge of waterbed mattress adjacent each corner. The material is either connected directly to the mattress or attached to a strip of material that extends beneath the mattress and is secured there by the weight of the mattress. The Velcro material is attached to mating Velcro material formed on a mattress pad and/or a lower sheet. An upper sheet is similarly provided with Velcro material to engage or mate with such material on the lower sheet. The section of Velcro may be secured to the mattress by a section of elastic material which will facilitate holding the bedding to the mattress but yet accommodate relative movement of the mattress and bedding.
