More lumbar pressure is not always better

Lumbar support is meant to meet the inward curve of the lower back while you are seated back in the chair. If it presses against the wrong area, feels overly aggressive or pushes you forward, turning it up further is unlikely to help. Start by resetting the chair and changing one setting at a time.

Use this setup sequence

Set seat height first. Sit with your feet supported and your thighs comfortable.
Set seat depth. Sit fully back and leave a small gap behind the knees. If the seat is too deep, you may slide forward and lose contact with the backrest.
Find the lower-back curve. The lumbar support should meet the small of your back, not your belt line and not the middle of your back.
Start gentle. Use the lowest comfortable depth or tension, then make small changes over a few work sessions.
Check recline and armrests. A recline setting or armrest height that pulls you forward can change how the lumbar area feels.

Common symptoms and what to check

What you notice	Check first
Support feels too high	Lower the lumbar position and confirm you are sitting fully back.
Support feels too firm	Reduce depth or tension and reassess seat depth and recline.
You slide forward	Check whether the seat is too deep or the lumbar support is too aggressive.
Feet cannot reach the floor	Set chair and desk height together; use a stable footrest if needed.

Know when to pause

A new chair can feel unfamiliar while you learn its adjustments. Sharp pain, numbness, persistent pain or symptoms that do not improve after sensible setup changes are reasons to stop treating this as a furniture adjustment problem and seek appropriate professional advice.

Frequently asked questions

Should lumbar support be in the middle of my back?

No. Start at the inward curve of the lower back, then make small adjustments for your body and chair design.

Should I remove lumbar support if it feels uncomfortable?

First check chair height, seat depth, lumbar position and firmness. If the chair cannot be made comfortable, consult the chair maker instructions or consider a different fit.

How to use this guide for your own setup

Test the fit at your own desk

An ergonomic chair is only useful when its adjustments work with your body and desk. Begin with seat height: your feet should have a stable surface, while your knees and hips feel comfortable rather than forced into a position. Then check seat depth. Sit fully back and leave a small gap behind the knees; if the seat presses into the back of the legs, try a shallower setting or a different chair.

Work through the controls in order

Set the chair height and seat depth first.
Place lumbar support in the curve of your lower back, then reduce or increase its pressure gradually.
Adjust armrests so the shoulders can relax while the forearms have light support.
Set the backrest and headrest last. A headrest should support rather than push the head forward during normal computer work.

Bring your setup into the decision

Measure desk height, armrest clearance beneath it, and the distance to the monitor. If you can, sit for at least several minutes in your usual work posture and test typing, mousing, reclining and standing transitions. ULTI’s showroom is useful for a real fit check, while the chair adjustment guide helps you revisit the settings after delivery.
