    摘要： A sofa bed includes: a plurality of elastic modules; a body frame having slide rails arranged thereon; and armrest frames disposed at two sides of the body frame along a longitudinal direction of the body frame, respectively. The slide rails on the body frame are configured to enable the plurality of elastic modules to be mounted on the body frame from an outside of the body frame and to slide thereon to predetermined mounting positions, such that the body frame at one side facing the user is provided with the plurality of elastic modules. The angle between the seat and the backrest portion can be locked for improved operation. The elastic modules, which can be easily installed and uninstalled, can improve the comfort of the sofa bed.

    摘要： A cushioning element includes a plurality of interconnected walls that define hollow columns. The interconnected walls include voids. The voids have shapes, sizes, and positions that reduce an overall density and weight of the cushioning element without sacrificing its cushioning characteristics. The cushioning element may even be thinner than an existing, conventionally configured cushioning element while providing the same or improved cushioning. In some embodiments, the cushioning element may also include enlarged junctions between interconnected walls or other stiffening features. Methods for designing such cushioning elements are also disclosed.

    摘要： Described are wooden coil springs, including those made of non-compressed wood, and mattresses with such coil springs. Also described is a method of producing a coil spring made of non-compressed wood, which includes winding a slat on reel, steaming and drying to produce the wooden coil spring. Such a coil spring may have a cylindrical shape, a cone shape or a truncated cone shape, and may have a substantially perpendicular end turn with respect to the longitudinal axis of the coil spring.

    摘要： Disclosed herein is a method of making a spring core (12) for a bedding or seating product (10). The spring core (12) has coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one arcuate leg (76) longer than the other (78), the legs (76, 78) being joined by a connector (80) having an arcuate bump (81) therein. The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to being wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.
