What Knoll highlights

  • Steel wire rod base

    The base is built from steel wire rods. Knoll says pieces in Platner's wire collection need as many as 1,000 welds each.

  • Upholstered shell

    A molded fiberglass shell carries a molded latex foam cushion, upholstered in your choice of fabric.

  • Floor protection

    A plastic ring under the base protects floors. Knoll lists the chair as Greenguard certified for low emissions.

As described by Knoll on its official pages; not a Chairpedia assessment.
