Abstract
An article of furniture includes a frame defining an opening, and a suspension material spanning over the opening and having a weft knit construction. The suspension material is configured to support a user, and the suspension material includes at least one multifilament forming a jersey knit structure which has a plurality of courses extending in a course direction and a plurality of wales extending in a wale direction, and at least one monofilament corresponding to and being inlaid in a respective one of the courses. The suspension material has, in the course direction, a ratio of machine gauge, in needles per mm, to course stiffness, in N per mm, between 0.02 and 0.2 and has, in the wale direction, a ratio of machine gauge, in needles per mm, to wale stiffness, in N per mm, between 0.07 and 1.4.

An article of furniture comprising:
- a frame defining an opening;
- and
- a suspension material spanning over the opening and having a weft knit construction, the suspension material configured to support a user, the suspension material including:
- at least one multifilament forming a jersey knit structure which has a plurality of courses extending in a course direction and a plurality of wales extending in a wale direction, and
- at least one monofilament corresponding to and being inlaid in a respective one of the courses,
- wherein the suspension material has, in the course direction, a ratio of machine gauge, in needles per mm, to course stiffness, in N per mm, between 0.02 and 0.2 and has, in the wale direction, a ratio of machine gauge, in needles per mm, to wale stiffness, in N per mm, between 0.07 and 1.4.
An article of furniture comprising:
- a frame defining an opening;
- and
- a suspension material spanning over the opening and having a weft knit construction, the suspension material configured to support a user, the suspension material including:
- at least one multifilament forming a jersey knit structure which has a plurality of courses extending in a course direction and a plurality of wales extending in a wale direction, and
