custom additions

  • Optional embroidery.

    Embroidered logos.

    It is recommended that embroidered logos only be placed on the front or back of the Voss high back headrest, due to the pronounced stitch work that runs down the center of the front and back of these chairs. Embroidered logos can also be placed on the front of the Voss mid back headrest, due to this signature stitch work. This unique customization should be placed at least 1 inch from the top, bottom & sides of the chair.

Seat Reference Point (SRP),
The ergonomic seat depth measurement.

 

Measurement G (and not measurement H) is the true seat reference point. SRP is an ergonomic term that defines where there is a slight indentation in the lumbar (i.e. where the sitter is benefiting from the lumbar support) to the front edge of the seat. It gives the true measurement of surface area in contact with the body. It is very useful for correctly matching up with hip to knee measurements for ergonomists taking into account the two – three finger gap between the back of the leg to the edge of the seat. It is very important to ensure no restriction in circulation to the lower extremities (lower legs and ankles).
