bed functional sofa

A functional sofa bed needs a good quality frame, with a good design. As previously stated, most actions of sofa beds function by pulling the lower part of the sofa up, and the back then goes down. To create a functional sofa bed, the action has to be smooth and most importantly reliable. It also has to be strong enough to take up to three people sitting and two people sleeping on it, along with being moved twice a day.

A chaise longue (French "long chair") is an upholstered couch in the shape of a chair that is long enough to support the legs.

It is often also called "chaise lounge" in North America, particularly in the furniture industry. This spelling and pronunciation has become well-established and can be found in American English dictionaries, and is an example of a folk etymology.

Note also that in modern France, the term chaise longue often refers to any long reclining chair such as a deckchair.
