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.

What is the most popular bed size?

Queen size beds are the most popular bed size and is used by roughly 50% of people across varied age groups. The second most popular bed size is the King size bed (20%) followed by the Full size bed (15%).

What size bed should I get?

Choosing a bed size should be based on a variety of factors including bedroom size, a person’s body type and height, and their relationship status (married, couple, or single). Most single sleepers can use nearly every mattress size, while couples prefer larger bed sizes from Queen to California King.

What is the largest bed size?

The largest bed size in production is the Alaskan King bed measuring 108” x 108” (274 x 274 cm). The largest bed in history was custom built for the summer festival of St. Gregorius in Hertme, Netherlands in 2011 and measured 87’ x 54’ (26.5 x 16.44 m).
