A sofa bed or sofa-bed (in the US often called a sofabed, hide-a-bed, bed-couch, sleeper-sofa, or pullout sofa) is a multifunctional furniture typically consisting of a sofa or couch that, underneath its seating cushions, hides a metal frame and thin mattress that can be unfolded or opened up to make a bed. A western-style futon differs from a sofa bed, although sofa beds using futon mattresses are common.

History

Leonard C. Bailey filed a patent for the first "folding bed" on July 18, 1899. The metal bed frame could be folded, and the bent mattress could be closed for use if needed. Later, it was known as a "hide-a-bed".

Rudolf Coopersmith filed a patent for the Davenport bed in 1905. Between 1905 and 1947, Coopersmith filed over 30 patents for mechanical parts of sofa beds, mattresses, and mattress manufacturing machinery. In 1925, he took out a patent for the sofa bed, the precursor of the modern-day pullout sofa.

William Lawrence Murphy took out a patent for making "In-A-Dor bed", which is known as a "Murphy bed" today. The folded space-saver into a wall closet characterizes it.

In 1931, Bernard Castro made and sold the "Castro convertible" by using $400 from his savings. Castro's design is the evolution of most sofa beds sold nowadays.

After mimicking the Japanese founders, the futon appeared in the United States around 1980. William Brouwer developed the first sofa convertible frame style in the United States.

A "slide away bed" can refer to a sofa bed that slides to the wall to form a sofa, with the mattress hinged to form a seating surface and back support. The bed frame support is a telescoping frame that allows the bed platform to recess below the seating cushion. The primitive version of the Slide Away Bed was invented by Manning Lane, Warren J. Hauck and Roy O. Sweeney of Cincinnati, Ohio. The knock-down sofa bed with hinged mattress patent was filed on September 5, 1978, and issued on May 27, 1980. [1] [2]

Mattress types

Although most sofa beds use a queen short mattress measuring 150 cm × 185 cm (60 in × 72 in), other common sizes include 145 cm × 185 cm (58 in × 72 in), 135 cm × 185 cm (54 in × 72 in), and 130 cm × 185 cm (52 in × 72 in). The average sofa bed mattress thickness is 11 cm (4.5 in). Sofa mattresses can be produced out of many different materials; the majority are made of springs or foam.[ citation needed ]

Spring sofa mattress

Spring sofa mattresses usually contain:

Pocket coil construction

Pocket-coil mattresses are mattresses with coils resting inside the base of the mattress. Each coil is encased in a pocket, allowing the mattress to keep its shape over time.

Slide-away bed

A slide-away bed is a sofa bed that slides to the wall to form a sofa. The mattress is hinged to create a seating surface and back support. The bed frame support is a telescoping frame that allows the bed platform to recess below the seating cushion.

Sleeping chair

A sleeping chair, armchair bed or chair bed can differ from sleeper sofas or futons in that they are made for a one-person width, [3] which is reflected by them sometimes being referred to as single sofa bed chairs. Some sleeping chairs are multifunctional furniture that can also function as a chaise longue or recliner when upright.

<span class="mw-page-title-main">Couch</span> Furniture for seating two or more people

A couch, also known as a sofa, settee, chesterfield, or davenport, is a cushioned item of furniture for seating multiple people. It is commonly found in the form of a bench with upholstered armrests and is often fitted with springs and tailored cushion and pillows. Although a couch is used primarily for seating, it may be used for sleeping. In homes, couches are normally put in the family room, living room, den, or lounge. They are sometimes also found in non-residential settings such as hotels, lobbies of commercial offices, waiting rooms, and bars. Couches can also vary in size, color, and design.

A bedroom or bedchamber is a room situated within a residential or accommodation unit characterised by its usage for sleeping. A typical western bedroom contains as bedroom furniture one or two beds, a clothes closet, and bedside table and dressing table, both of which usually contain drawers. Except in bungalows, ranch style homes, ground floor apartments, or one-storey motels, bedrooms are usually on one of the floors of a dwelling that is above ground level. Beds range from a crib for an infant; a single or twin bed for a toddler, child, teenager or single adult; to bigger sizes like a full, double, queen, king or California king). Beds and bedrooms are often devised to create barriers to insects and vermin, especially mosquitoes, and to dampen or contain light or noise to aid sleep and privacy.

<span class="mw-page-title-main">Mattress</span> Large soft sheet for lying on to sleep

A mattress is a large, usually rectangular pad for supporting a lying person. It is designed to be used as a bed, or on a bed frame as part of a bed. Mattresses may consist of a quilted or similarly fastened case, usually of heavy cloth, containing materials such as hair, straw, cotton, foam rubber, or a framework of metal springs. Mattresses may also be filled with air or water.

<span class="mw-page-title-main">Bed size</span> Dimensions of sleeping mattresses

Standard bed sizes are based on standard mattress sizes, which vary from country to country. Bed sizes also vary according to the size and degree of ornamentation of the bed frame. Dimensions and names vary considerably around the world, with most countries having their own standards and terminology. In addition, two mattresses with the same nominal size may have slightly different dimensions, due to manufacturing tolerances, amount of padding, and support type. Mattress sizes may differ from bedding sizes.

<span class="mw-page-title-main">Bedding</span> Bed covering fabrics

Bedding, also called 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 are often washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures. Most standardized measurements for bedding are rectangular, but there are also some square-shaped sizes, which allows the user to put on bedding without having to consider its lengthwise orientation.

<span class="mw-page-title-main">Box-spring</span> Type of bed base

A box-spring is a type of bed base typically consisting of a sturdy wooden frame covered in cloth and containing springs. Usually, the box-spring is placed on top of a wooden or metal bedframe that sits on the floor and acts as a brace, except in the UK where the divan is more often fitted with small casters. The box-spring is usually the same size as the much softer mattress placed on it. Working together, the box-spring and mattress make up a bed. It is common to find a box-spring and mattress being used together without the support of a frame underneath, the box spring being mounted directly on casters standing on the floor.

<span class="mw-page-title-main">Memory foam</span> Component primarily utilized for making cushions or mattresses

Memory foam consists mainly of polyurethane with additional chemicals that increase its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu). The foam bubbles or ‘cells’ are open, effectively creating a matrix through which air can move. Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover their original shape more quickly.

Upholstery coil springs are an important part of most modern upholstery. The consumer usually never sees the construction features of an upholstered piece. The overall quality of the materials and construction dictate the comfort level of an upholstered piece and its ability to satisfy the consumer over the long term. A basic upholstered piece may be composed of a frame, springs, foam, cushioning, padding, and textiles.

<span class="mw-page-title-main">Multifunctional furniture</span>

Multifunctional furniture is furniture with several functions combined. The functions combined vary, but a common variant is to incorporate an extra storage function into chair, tables, and so forth, making them so-called storage furniture. It more efficiently uses up living space. Lack of space can be an important reason for choosing such furniture, but combination furniture is also seen in larger homes for more space-efficient utilization. Historically, furniture with transforming mechanisms was called "mechanical furniture".
