Bed Sizes | Mattress Sizes

Beds are furniture pieces that are used for sleeping or reclined relaxing. Found in residential bedrooms and hotel rooms, beds are typically comprised of a mattress, frame, and often include a headrest. While most beds consist of a single fixed mattress, other varieties of beds include sofa beds, Murphy beds, inflatable beds, and bunk beds. Bed mattresses over time have evolved from being stuffed with straw, wool, and leaves to quilted metal spring frameworks, water beds, portable air-filled mattresses and modern memory foam mattresses. Beds are topped with pillows, sheets, duvets and optional blankets and are often accompanied by bedroom furniture such as bedside tables and table lamps.
