It normally has a soft [[mattress]] on a [[bed frame]]. Many beds also have [[bed sheet]]s to cover the mattress and additional sheets for the people to sleep under. People also use a pillow under their heads. A bed comes in many different sizes including a single, double and king size. ==History== [[File:A 10 feet high ancient bed in National Museum of Bangladesh collected from Lohagara,Narail.jpg|thumb|A 10 feet high ancient bed in National Museum of Bangladesh]] [[File:Cama de madeira.jpg|thumb|Bed.]] In August 2020 [[archaeologists]] reported the discovery of the oldest grass bedding from Middle [[Paleolithic]] (at least 200,000 years ago).<ref name=Ash>{{cite news |title=200,000 years ago, humans preferred to sleep in beds |url=https://phys.org/news/2020-08-years-humans-beds.html |access-date=6 September 2020 |work=phys.org |language=en |archive-date=19 August 2020 |archive-url=https://web.archive.org/web/20200819030258/https://phys.org/news/2020-08-years-humans-beds.html |url-status=live }}</ref> This was much older than the oldest previously known bedding.
