Futon mattresses are widely used due to their comfort. They are made up of two parts namely the frame and mattress. To determine how big is a futon mattress, you must familiarize yourself with these parts.
Futon mattresses are considered to have come from Japan. Japanese futon mattresses are not like the ones that are popular in western culture since they are simply mattresses, which are foldable and can be stored in closets when not in use.
They are laid out on the floor and are accompanied by the usual beddings used in western style beds. It is a widespread practice in Japan, so it identifies easily with the Japanese culture.
While the western types of beds and mattresses are steadily gaining fans everywhere, the manner at which the Japanese people use futon mattresses is a deeply ingrained way of life. Similar practices may be seen in other countries, but none has stood out to associate closely to this practice the way Japan has.
Strictly speaking, futon mattresses can either be the traditional Japanese kind, or a convertible type that can be switched between a sofa or chair and a bed. The term futon has almost become synonymous with the latter.
Traditional futons are simply mattresses alone. They are folded and stored when it is not being used. The modern futon is a furniture that is mostly a sofa, which converts to a bed when needed. Under this would be bi-fold futons and futon loungers.
Bi-folds come with frames that fold into two. Half of the furniture folds up or down to become a sofa or a bed. A lounger has extendable legs hidden within the frame, which holds an extra length of the mattress.
Japanese futons have adapted the standard bed sizes popular in western countries. These are single, twin, queen, and king sizes.
These are the market terms that refer to specific measurements that manufacturers use when making their products. It usually refers to the length and width of the mattress.
The thickness of the mattress is a matter of preference for the manufacturer. The thickness can vary between products and should be considered especially if it affects the fit between products, like the fit of the mattress to the futon frame or the mattress to the fitted sheet.
When it comes to modern futons, these size groups usually dictate the sizes: chair, twin, full, and queen. A king size futon is not practical, as its size and weight will make it next to impossible to convert between the two different forms.
Futon mattresses came from Japan where these usually refer to mattresses alone, without the frame, that can be folded away after use. These are stored in closets along with other beddings, only to be taken out again at night to be used when sleeping. In western countries, the term futon has come to mean a piece of convertible furniture, which is composed of a mattress and a frame that changes between a sofa and a bed.
Most modern futons can be divided into two groups: the bi-folds and the loungers. These two differ whether an ottoman is built-in or not.
Both have a portion of the frame that can be propped up to become the backrest of a chair, which can be laid out flat to convert the whole thing into a bed. Both will need an ottoman added in if it is to be used as a bed.
There are four different size groups: chair, twin, full, and queen. There is no king, as the size of the standard king is too bulky to manipulate to convert between the two different forms.
Length is usually 54 inches, except the queen lounger which is at 60 inches. The width goes up as we go up in the different size groups. Additional inches can be added to the length with the addition of the ottoman mattress so that the futon can be used as a bed.
