Bedding

Bedding, also known as bedclothes, 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 Antipodean English, bedding is often called manchester.

A set of bedding usually consists of a flat or fitted bed sheet that covers the mattress; a flat top sheet; either a blanket, quilt, or duvet, sometimes with a duvet cover which can replace or be used in addition to the top sheet; and a number of pillows with pillowcases, also referred to as pillow shams. (See #Terminology for more info on all these terms.) Additional blankets, etc. may be added to ensure the necessary insulation in cold sleeping areas. A common practice for children and some adults is to decorate a bed with plush stuffed animals, dolls, and other soft toys. These are not included under the designation of bedding, although they may provide additional warmth to the sleeper.

Bedding (horticulture)

Bedding, in horticulture, refers to the temporary planting of fast-growing plants into flower beds to create colourful, temporary, seasonal displays, during spring, summer or winter. Plants used for bedding are generally annuals, biennials or tender perennials; succulents are gaining in popularity.

Some bedding plants are also referred to as "patio plants" because they are widely used in pots and other containers positioned on patios, terraces, decking and other areas around houses. Larger tender "conservatory plants" may also be moved out from greenhouses or conservatories and planted out in borders (or stood in their pots in sheltered positions) for the warmer months, then returned to shelter for the winter.

The modern bedding plant industry breeds and produces plants with a neat, dwarf habit, which flower uniformly and reliably. They are bred primarily for use in large-scale bedding schemes where uniformity and predictability is of paramount importance, but this is often achieved by losing the plants' individual character, and has been criticised by such notable plantsmen as the late Christopher Lloyd, who championed an informal style of bedding.

Bed (geology)

In geology a bed is the smallest division of a geologic formation or stratigraphic rock series marked by well-defined divisional planes (bedding planes) separating it from layers above and below. A bed is the smallest lithostratigraphic unit, usually ranging in thickness from a centimetre to several metres and distinguishable from beds above and below it. Beds can be differentiated in various ways, including rock or mineral type and particle size. The term is generally applied to sedimentary strata, but may also be used for volcanic flows or ash layers.

In a quarry, a bedding is a term used for a structure occurring in granite and similar massive rocks that allows them to split in well-defined planes horizontally or parallel to the land surface.

Engineering considerations

In geotechnical engineering a bedding plane often forms a discontinuity that may have a large influence on the mechanical behaviour (strength, deformation, etc.) of soil and rock masses in, for example, tunnel, foundation, or slope construction.
