August 2020 scientists reported the discovery of the oldest grass bedding from at least 200,000 years ago, much older than the oldest previously known bedding. They speculate that insect-repellent plants and ash layers, sometimes due to burned older grass beddings, found beneath the bedding have been used for a dirt-free, insulated base and to keep away arthropods. Ancient history Early beds were little more than piles of straw or some other natural material (e.g. a heap of palm leaves, animal skins, or dried bracken). An important change was raising them off the ground, to avoid drafts, dirt, and pests. In the Miocene period, lasting from twenty-three to five million years ago, before the emergence of humans, apes began creating beds composed of a sleeping platform including a wooden pillow. Sub-Saharan Africa Bedding dated around to 3600 BC was discovered in Sibudu Cave, South Africa. The bedding consists of sedge and other monocotyledons topped with the leaves of Cryptocarya woodii. Europe Beds found in a preserved northern Scottish village, which were raised boxes made of stone and likely topped with comfortable fillers, were dated to between 3200 BC and 2200 BC. The Odyssey, an ancient Greek epic poem, describes the bed of its protagonist, Odysseus, and explains that he crafted the bed for himself and his wife, Penelope, out of a huge olive tree trunk that used to grow on the spot. The poem's author, Homer, also mentions the inlaying of the woodwork of the bed with gold, silver, and ivory. Ancient Roman mattresses were stuffed with reeds, hay, or wool. Feathers were used towards the end of the Republic, when custom demanded luxury. Small cushions were placed at the head and sometimes at the back. The bedsteads were high and could only be ascended by the help of steps. They were often arranged for two people, and had a board or railing at the back, as well as the raised portion at the head. The counterpanes were sometimes very costly, generally purple embroidered with figures in gold; and rich hangings fell to the ground masking the front. The bedsteads themselves were often of bronze inlaid with silver, and Elagabalus had one of solid silver. In the walls of some houses at Pompeii bed niches are found which were probably closed by curtains or sliding partitions. Ancient Romans had various kinds of beds for repose. These included: lectus cubicularis, or chamber
