These bed risers give you storage space you never had before. These sturdy blocks instantly elevate your bed for up to 6-Inch of additional under-bed storage space, perfect for those extra large storage bins. They are engineered to be incredibly strong, and can also be used to aid in the treatment of some medical conditions. These bed risers are perfect for any dorm room setting. Bed raisers are an amazing way to gain approximately 6-inches of storage space (in that ever so important unused space under the bed). They are also great for medical use, two under the front of the bed can help improve circulation in the legs, or two under the back legs can help people with acid reflux.
