Abstract: A mattress support element is presented formed from a combination of natural plant material and processed plant material. The processed plant material forms a framework of cells. Each cell contains one or more freestanding cylindrical sections. The cylindrical sections provide limited range piston-like movement within the cell, and may be made of natural plant materials. The cylindrical sections and the framework rest on a fabric base. The cylindrical sections stand taller than the framework. A ceiling layer of fabric overlays the cylindrical sections and framework, thereby constraining the cylindrical sections to remain in their respective cells. One or more layers of upper padding or cushioning may rest over the support element, and one or more layers of lower padding may rest under the support element.
