Liggbasis

Liggbasis is a term found in Norwegian and other Scandinavian design and medical equipment literature that refers to the base or foundational structure of a lying surface, such as a bed, examination table, or reclining lounge. In English-language contexts the concept is usually described as a bed frame or base frame, but liggbasis is used as a compound term in regional documentation and product catalogs.

A liggbasis serves as the load-bearing component of the product. It distributes weight from the mattress or padding to the floor or supporting frame, contributes to overall stability, and provides a mounting point for other mechanisms. Depending on the design, it may incorporate features such as height adjustment, tilt or articulation, and attachment points for wheels or feet. The base is typically engineered to meet safety and ergonomic requirements, including load capacity, rigidity, and compatibility with mattress sizes.

Variants of liggbasis commonly include fixed bases, which provide a stationary support; adjustable bases, which incorporate manual or powered height and angle adjustments; and modular bases, designed to accept different configurations or mattress types. Materials range from metal frames with reinforcing cross-members to composite or wood alternatives, chosen for strength, weight, and cost considerations.

Applications span medical and healthcare settings, rehabilitation furniture, and consumer ergonomic beds or lounge furniture. In clinical environments, the liggbasis often interfaces with side rails, headboards, or patient transfer systems to enhance safety and usability.

Etymology: ligg means “to lie down” in Norwegian, and basis derives from Latin. The term is primarily used in Scandinavian contexts and may not be common in English-language specifications. See also bed frame, base plate, foundation.
