In a treadle loom, the shedding is controlled by the feet, which tread on the [[treadle]]s.

The earliest evidence of a horizontal loom is found on a pottery dish in [[ancient Egypt]], dated to 4400 BC. It was a frame loom, equipped with treadles to lift the warp threads, leaving the weaver's hands free to pass and beat the weft thread.<ref>{{cite book |last1=Bruno |first1=Leonard C. |last2=Olendorf |first2=Donna |title=Science and technology firsts |date=1997 |publisher=[[Gale Research]] |isbn=9780787602567 |page=[https://archive.org/details/sciencetechnolog0000brun/page/2 2] |url=https://archive.org/details/sciencetechnolog0000brun |url-access=registration |quote=4400 B.C. Earliest evidence of the use of a horizontal loom is its depiction on a pottery dish found in Egypt and dated to this time. These first true frame looms are equipped with foot pedals to lift the warp threads, leaving the weaver's hands free to pass and beat the weft thread.}}</ref>

A pit loom has a pit for the treadles, reducing the stress transmitted through the much shorter frame.<ref name="Know Your Handlooms"/>

In a wooden vertical-shaft loom, the [[heddle]]s are fixed in place in the shaft. The warp threads pass alternately through a heddle, and through a space between the heddles (the [[shed (weaving)|shed]]), so that raising the shaft raises half the threads (those passing through the heddles), and lowering the shaft lowers the same threads — the threads passing through the spaces between the heddles remain in place.

A treadle loom for figured weaving may have a large number of harnesses or a control head. It can, for instance, have a [[Jacquard machine]] attached to it<ref>{{Cite web|url=https://artless-store.com/blogs/the-artless-way/handloom-vs-powerloom|archive-url = https://web.archive.org/web/20201201174856/https://artless-store.com/blogs/the-artless-way/handloom-vs-powerloom|archive-date = 2020-12-01|title = Handloom VS Powerloom|date = 19 March 2020}}</ref> {{see above|Loom#Shedding methods}}.
