A vehicle seating assembly includes a seatback frame. A bolster insert is positioned on a side bolster of the seatback frame. A foam layer is positioned over the seatback frame. A trim cover is positioned over the foam layer. The foam layer and the trim cover are contoured to expose the bolster insert.

A foam part (5, 105, 205, 305), in particular for a vehicle seat, includes a first foam layer (11, 111, 211, 311) facing a user and a second foam layer (21, 221) facing away from the user. The first foam layer has a hardness and/or density that is different from the hardness or density of the second foam layer (21, 221). The first foam layer includes several comfort tubes (50, 150, 250, 350) facing the user. A method for producing such a foam part (5, 105, 205, 305) includes a first step in which the first foam layer, having the comfort tubes (50, 150, 250, 350), is foamed and a second step in which the second foam layer (21, 221) is foamed. A tool (500) for producing a foam part (5, 105, 205, 305) includes a bottom part (510), a frame (520), and a top part (530).

There is provided a vehicle seat including: a seatback frame that includes a plate-shaped back face panel portion; a headrest; a seatback pad that is provided at a front face side of the seatback frame, with a space formed between the seatback pad and the back face panel portion; a back spring that is formed from wire and includes left and right side portions extending in an up-down direction of the seatback, at both seat width direction sides inside the space, and includes a lower portion coupling together lower end portions of the left and right side portions in the seat width direction, wherein the left and right side portions are supported so as to be capable of undergoing displacement toward a seat width direction outer side with respect to the seatback frame, and support the seatback pad from a seat rear side.

A back pad assembly for a material handling vehicle is provided that includes a back pad, a framework, and a mounting frame. The back pad includes a center portion, a first side portion, and a second side portion. The first side portion defines a first curved profile, and the second side portion defines a second curved profile. The first curved profile and the second curved profile are arranged on laterally-opposing sides of the center portion. The framework includes a first mounting bar and a second mounting bar. The framework is coupled to the back pad. The first and second mounting bars are adjustably supported by the mounting frame to enable the back pad to be selectively mounted at varying heights along the mounting frame.

A motor vehicle seat having a structural frame that includes an upper cross-member, and a backrest module having a foam block and a support arranged below the foam block to support that foam block. The seat includes an upper locking element carrying the support and removably connected to the upper cross-member.
