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.

A mattress assembly includes a cover having a pocket. A mattress is positioned within the pocket. The mattress includes opposite first and second sides, the first side having a cavity. An insert is positioned within the cavity. Methods of use are disclosed.

Embodiments of a mattress and methods of manufacturing the same, wherein the mattress includes a body having one or more openings for removable inserts that a user can position within the openings to adjust the mechanical characteristics of the mattress, including the amount and location of support provided by the mattress to the user. Some embodiments of the mattress include one or more covers, such as a fire-retardant cover, that can encompass the mattress body while still allowing a user to access the openings of mattress body.

A spring element (1) having a pair of sleeves formed of two sleeves (5, 7) is disclosed. Each sleeve (5, 7) of the pair of sleeves is formed of a closed band. The two oppositely disposed sleeves (5, 7) are connected to each other by a connecting piece (9) at one point of their circumference, respectively. On each sleeve (5, 7), a projection (11a, 11b) directed towards the opposite sleeve (7, 5) is provided, spaced apart from the connecting piece (9). In this way, a receiving space (13) defined by the connecting piece (9) and the projections (11a, 11b) is formed between the sleeves (5, 7). A spring comprises a rod-shaped central bar (21) and such a spring element (1). The spring element (1) is slid onto the central bar (21) such that a portion of the central bar (21) is held in the receiving space (13) of the spring element (1) and can be removed without damage from the receiving space (13) of the spring element (1). This spring is provided for a mattress for lying and/or seating means comprising a mattress body made of a material movable in itself, particularly foam or latex, having hollow spaces arranged transversely to a longitudinal axis or a lateral axis. A spring is provided in at least one hollow space.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.
