Check Where The Backrest Makes Contact
The first comparison should be between the backrest shape and the people who will sit against it. Ask each participant to settle into a normal working position, then note where the backrest makes contact and where it does not. Because there is no back-height adjustment, changing the vertical position of that contact is not an available response. Compare office chairs with this limitation clearly recorded, while assessing any other verified settings separately. A chair that suits one colleague should still be assessed independently by another, particularly where the same workstation serves people with different body proportions.
Separate The Two Missing Features
Office chairs without lumbar support or back-height adjustment combine two separate considerations: the absence of lumbar support and the inability to reposition the backrest vertically. Neither characteristic tells you whether the backrest tilts, how the seat moves or which other adjustments are available. Establish those details individually before making comparisons. Otherwise, a broad description such as fixed seating could conceal differences that matter at the desk. A useful assessment sheet gives each characteristic its own entry and leaves unconfirmed features unresolved. This makes discussions more precise when several colleagues evaluate seating and prevents one missing adjustment from being mistaken for another.
