Bed risers are small platforms or blocks placed under the legs of a bed to increase its height. They come in various materials, such as plastic, wood, or metal, and can raise a bed by several inches. This added height can create extra storage space underneath, making it easier to store items like boxes or shoes. Using bed risers can also improve accessibility for individuals with mobility issues, making it easier to get in and out of bed. Additionally, they can enhance the overall aesthetic of a room by allowing for a more open and spacious feel.
