A duvet is a type of bedding consisting of a soft flat bag filled with down, feathers, wool, silk or a synthetic alternative, and typically protected with a removable cover, analogous to a pillow and pillow case.

Sleepers often use a duvet without a top bed sheet, as the duvet cover can readily be removed and laundered as often as the bottom sheet.

Duvets originated in rural Europe and were filled with the down feathers of ducks.

The best quality is taken from the eider duck, for its down is known for its effectiveness as a thermal insulator.

A mattress protector is an item of removable bedding that sits on top of, or encases, a mattress to protect it.

Some mattress protectors also provide protection to the person sleeping on the mattress from allergens and irritants such as dust mites, bed bugs, mold, and dead skin (like dandruff).

Bedding, also known as bedclothes or bed linen, is the materials laid above the mattress of a bed for hygiene, warmth, protection of the mattress, and decorative effect.

Bedding is the removable and washable portion of a human sleeping environment.

Multiple sets of bedding for each bed will often be washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures.

In American English, the word bedding generally does not include the mattress, bed frame, or bed base (such as box-spring), while in British English it does.

In Australian, South African and New Zealand English, bedding is often called manchester.

Yorkshire (abbreviated Yorks), formally known as the County of York, is a historic county of Northern England and the largest in the United Kingdom.

Due to its great size in comparison to other English counties, functions have been undertaken over time by its subdivisions, which have also been subject to periodic reform.

Throughout these changes, Yorkshire has continued to be recognised as a geographical territory and cultural region.

The name is familiar and well understood across the United Kingdom and is in common use in the media and the military, and also features in the titles of current areas of civil administration such as North Yorkshire, South Yorkshire, West Yorkshire and East Riding of Yorkshire.

A sheet is a rectangular piece of cloth used as bedding, being placed immediately below or above bed occupants.

Bed sheets can generally be divided into two categories: "top" and "bottom" sheets.
