Abstract: A seat cushion element may have at least one cushion element, a cover fastening mechanism and a cover element. The cushion element, the cover fastening mechanism and the cover element may form a pre-mounted unit and are arrangeable as such on a seat structure. The cover fastening mechanism may be premounted on a bottom side of the cushion element in a recess of the cushion element and the cover element may be arranged on a top side of the cushion element and is connected to the cover fastening mechanism through the cushion element. The cover element may have a connecting device by which the pre-mounted unit can be finally assembled on the seat structure. A vehicle seat having such a seat cushion element may also be made.

Abstract: The present invention relates to methods for the high fidelity synthesis of oligonucleotides and polynucleotides on a solid surface. In particular, the invention relates to methods of synthesising oligonucleotides, polynucleotides, and doublestranded polynucleotides/nucleic acids, such as DNA and XNA, wherein the process comprises thermally controlled deprotection steps at the 5?-OH of previously coupled nucleosides or nucleotides at selected sites on the surface of the substrate.
