Summary

A high-back RH task chair with a lockable tilt, separate back angle and inflatable lumbar support.

Best for

  • People who want to lock the tilt at any angle.
  • Lumbar support you can firm up; it is inflatable and moves in height.
  • Taller sitters; optional gas stems raise the seat to about 675 mm.

Good to check first

  • Armrests and the neckrest are options; add them when you configure.
  • The ESD version has a 5-year guarantee and no neckrest option.
  • Flokk sells it by quote, so ask for a price with your chosen options.

The trade-off

Many fine adjustments and a 10-year guarantee, sold by quote rather than at a published price.

What Flokk highlights

  • Lockable tilt

    The tilt mechanism moves without friction, adjusts steplessly and locks at any angle you choose.

  • Separate back and seat angle

    The back angle adjusts on its own, and the seat angle adjusts too. Seat depth adjusts with a slide.

  • Inflatable lumbar support

    The lumbar support is inflatable and sits 170 to 255 mm above the seat.

  • Five versions

    RH Logic 400 comes as Standard, Comfort, Elegance, Elite and ESD. The Elite adds 20 mm of extra padding.

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