Jenkkisänky

A jenkkisänky, commonly known in English as a box spring bed or American bed, is a type of bed construction popular in many parts of the world, particularly originating from North America. It consists of a foundational box-like structure, typically made of wood, which contains a metal spring system. This spring system is designed to provide support and absorb shock, enhancing the comfort and longevity of the mattress placed on top.

The primary function of the box spring is to elevate the mattress, making it easier to get in and out of bed. It also acts as a shock absorber, reducing the stress on the mattress from regular use. This can help to prolong the life of the mattress and maintain its shape and support. The box spring itself is usually covered in fabric to match the mattress or the bed frame and is often placed directly on a bed frame or on legs.

Jenkkisängyt are distinct from traditional slat beds, where the mattress rests on a series of wooden or metal slats. The solid, spring-filled base of a jenkkisänky offers a different feel and support system compared to slat beds. While historically a standard component of many beds, their prevalence has seen some variation with the introduction of other mattress types and bed bases. Modern designs may incorporate different spring types or alternative materials within the box spring structure.
