The mattress timeline is pretty much thousands of years of straw or bird feathers, and then a drastic change for the better in the last few years with the Blissful Nights Blossom 9 in. Bamboo Charcoal Memory Foam Mattress. This innovative mattress combines layers of memory foam with bamboo charcoal fibers that help resist bacteria while it neutralizes odor. The memory foam design shapes to the contours of your body to provide custom, even support from head to toe for the most advanced level of relaxation that you'll ever sleep through. The Wedge-edge design also adds strength to those last few edges on the outside of the mattress, making every single inch into a supportive place to catch some quality Z's. This mattress is offered in a range of standard sizes.
