What device prevents bed covers from resting on a resident's legs and feet?

A bed cradle is designed specifically to keep bed linens off a resident's legs and feet. This device provides a gentle elevation, ensuring that the covers do not apply pressure or cause discomfort, which is particularly important for residents with sensitive skin, wounds, or conditions such as arthritis. The use of a bed cradle can significantly improve comfort and promote healing by minimizing friction and pressure on the lower extremities.

The other options, while having their own purposes, do not serve this specific function. Bed rails are used for safety, helping to prevent falls by providing support when the resident needs to get in or out of bed. A footstool is primarily used to elevate the feet or provide support for getting into or out of bed but does not prevent covers from resting on the legs. A pillow would typically be used for head or neck support, and while it could potentially elevate legs when placed under them, it is not designed for the specific purpose of keeping bedcovers off the legs and feet.
