Most discomfort at a desk comes from a setup that was never adjusted to the person sitting there. The chair came out of the box at a default height, the monitor sits wherever the cable reached, and the keyboard lives on a surface built for an average body that nobody actually has.
The fix is not expensive gear. It is adjustable furniture and a setup done in the right order. This guide walks you through that order, what to measure, and how to buy adjustable pieces pre-owned so the budget goes further.
Why the order of adjustments matters
Every measurement at a workstation depends on the one before it. Your seat height determines where your elbows land, your elbow height determines the right work surface height, and your seated eye level determines monitor placement. If you set the desk first, you end up chasing it with the chair and never quite getting there.
Work from the floor up: feet, seat, back, arms, surface, screen, then lighting and habits.
Step-by-step ergonomic workstation setup
- Set seat height. Sit all the way back. Adjust until your feet rest flat on the floor and your thighs are roughly level, knees at or slightly below hip height.
- Set seat depth. Leave about two to four fingers of space between the front edge of the seat and the backs of your knees. If the seat pan slides, use it. If not, a lumbar adjustment can help shorten the effective depth.
- Adjust the lumbar support. Position it at the natural inward curve of your lower back. You should feel supported, not pushed forward.
- Tune recline and tilt tension. Set tension so the chair follows you when you lean back without forcing you upright or dumping you backward. Slight recline is easier on the spine than bolt-upright sitting.
- Set armrests. Lower them until your shoulders are relaxed and forearms rest lightly. Armrests that are too high hike your shoulders all day. Narrow them so your elbows stay close to your body.
- Set work surface height. With elbows near 90 degrees, your forearms should be about parallel to the floor while typing. Adjust the desk to meet your hands, not the other way around.
- Place the keyboard and mouse. Keep them close enough that your elbows stay at your sides. Wrists should stay neutral, not bent up or sideways.
- Position the monitor. About an arm's length away, with the top of the screen at or slightly below eye level. Center the primary screen in front of you. If you wear bifocals, drop it lower.
- Check lighting and glare. Place screens perpendicular to windows where possible and reduce overhead glare on the display.
- Build in movement. No posture is good for eight straight hours. Change positions, stand if your desk allows it, and take short breaks.
What adjustability to look for
An ergonomic setup is only as flexible as its least adjustable piece. Use this table when comparing chairs and desks, new or pre-owned.
| Feature | Why it matters | What to check on a pre-owned piece |
|---|---|---|
| Pneumatic seat height | Sets foot, knee and elbow position | Chair holds height under weight and does not sink |
| Seat depth adjustment | Fits short and tall thigh lengths | Slider moves and locks cleanly |
| Adjustable lumbar | Supports the lower back curve | Support moves and stays put |
| Tilt tension and lock | Controls recline resistance | Knob turns through full range, lock engages |
| Height and width adjustable arms | Keeps shoulders relaxed | Arm pads intact, adjusters click into place |
| Height-adjustable desk | Matches surface to elbow height, allows standing | Motor or crank runs smoothly, frame is level |
| Monitor arm | Sets screen height and distance precisely | Tension holds the screen without drifting |
Buying adjustable furniture pre-owned
High-end task chairs and adjustable desks are built for long commercial service, which is why they show up in good shape on the pre-owned market. Office Station sells pre-owned pieces from brands such as Herman Miller, Steelcase, Knoll, Haworth and Humanscale as an independent reseller, not an authorized dealer. Manufacturer warranties generally do not transfer to pre-owned furniture, so inspection matters.
Condition grades make that easier:
- Grade A, like new. Minimal visible wear. A good fit for client-facing areas.
- Grade B, very good. Light signs of use. The typical sweet spot for daily task seating.
- Grade C, good. Visible wear, fully usable. Worth considering for training rooms or overflow seating where budget matters most.
Cosmetic wear does not affect ergonomics. A working mechanism does. Before you buy, run every control through its full range.

Setting up ergonomics for a whole office
For a single desk, the steps above are enough. For a team, plan around ranges instead of one person.
- Standardize on one adjustable chair model so every user can be fit, and spare parts and training stay simple.
- Give each workstation enough surface depth to keep the monitor at arm's length. Shallow surfaces force screens too close.
- Mix tiers where it makes sense. A 6'x6' workstation, furniture only, runs $615 liquidation-grade, $1,245 remanufactured or $1,920 new. Prices exclude electrical, delivery and professional installation.
- Use free space planning to check clearances, sightlines to windows and walkway widths before anything is delivered.
- Budget for installation. Professional installation is $95 per workstation with a $495 minimum, and it means surfaces go in level at the heights you planned.
If you are replacing an older setup, the furniture you are retiring may offset part of the cost through office furniture liquidation, where a written net offer reflects resale value minus removal cost.

Frequently asked questions
What should I adjust first when setting up an ergonomic workstation?
Start with the chair. Seat height, depth and lumbar support set your body position, and every other measurement, including desk and monitor height, follows from where you sit. Adjusting the desk first usually means redoing it later.
Are pre-owned ergonomic chairs as adjustable as new ones?
The adjustment range is built into the chair model, so a pre-owned task chair offers the same controls it did when new, provided every mechanism works. Check each lever, the gas cylinder and the tilt tension before you commit. Condition grades help you judge wear on upholstery and finishes.
Do manufacturer warranties come with pre-owned chairs?
Generally no. Office Station is an independent reseller, not an authorized dealer, and manufacturer warranties generally do not transfer to pre-owned furniture. Ask about the specific piece and inspect its mechanisms so you know what you are buying.
How high should my desk be?
With your chair set correctly and shoulders relaxed, your elbows should rest near 90 degrees with forearms roughly parallel to the floor while typing. If your desk is fixed and too high, raise the chair and add a footrest. A height-adjustable desk removes that compromise.
Can you help plan ergonomic workstations for a whole office?
Yes. Space planning is free, and you can price workstations across liquidation-grade, remanufactured and new tiers. Installation is available at $95 per workstation with a $495 minimum.
