What We Like

  • The arms adjust in height, width, depth and pivot (4D), and the listing puts them 23 to 32.5 inches off the floor.
  • Seat height runs from 16.5 to 21.5 inches, and the seat depth adjusts between 15.5 and 17.75 inches.
  • It weighs 30 lb and is rated for 400 lb, with a lumbar system named as LiveBack flexor system.

Watch Out For

  • The listing does not state a warranty term, nor whether the headrest adjusts in height or angle. Its Ergo Score of 25 is measured within Guest & Reception chairs on a basic profile, so do not compare it directly with the task-profile Series One listing.
  • Only 2 reviews back its 4.4 rating, among the fewest of any chair listed here.

At a Glance

A headrest and 4D arms are the headline features of this Series One, which also lists a LiveBack flexor system for the lumbar, a seat that adjusts in depth and a 21.5 inch backrest.

Who This Chair Is For

  • Anyone who wants arms they can move in four directions and set between 23 and 32.5 inches off the floor.
  • Buyers who prefer a tilt with automatic recline resistance that can be locked upright.

Who Should Look Elsewhere

  • Anyone who needs a stated warranty term before buying, since the listing does not state one.
  • Shoppers who want a wide spread of owner opinion, because only 2 reviews are available.

Four-way arms, a flexor lumbar and an upright lock on the Series One with Headrest
