People sit in an office chair for thousands of hours a year. That makes it one of the few pieces of furniture where a bad choice shows up as sore backs, fidgeting and chairs pushed into a corner. The five checks below cover what actually matters, and the last one explains how new and pre-owned chairs compare.
1. Fit to the person
Start with the body, not the brochure. A chair that fits the person using it beats a feature-packed chair that does not.
- Seat height: feet flat on the floor, thighs about level, knees near a right angle. Check the height range against your shortest and tallest users.
- Seat depth: sit all the way back. You should have roughly two to four fingers of space between the seat edge and the back of your knees.
- Seat width: enough room to sit without the side frame pressing on your hips.
- Back height: the backrest should support the curve of your lower back and reach at least your shoulder blades.
- Weight rating: confirm the model is rated for the people who will use it.
Many office chair models come in more than one size or have size options for the seat and back. If you are buying for a team, look for a model that covers your range of users with adjustment rather than buying a single size and hoping.
2. Adjustments that people will actually use
An adjustment that is hard to find is an adjustment nobody uses. Sit in the chair and try every control without instructions.
| Adjustment | What it does | What to check |
|---|---|---|
| Pneumatic height | Raises and lowers the seat | Holds its height and does not sink slowly |
| Seat depth slider | Moves the seat pan forward or back | Slides smoothly and locks in place |
| Lumbar support | Supports the lower back curve | Adjusts up and down or in depth, and sits where your back curves |
| Tilt tension | Sets how hard you push to recline | Changes the feel noticeably across its range |
| Tilt lock | Holds the back upright or at a set angle | Locks at more than one position |
| Armrests | Support the forearms and shoulders | Adjust in height and ideally width or pivot; low enough to slide under the desk |
For task seating used all day, height, lumbar, tilt tension and adjustable arms are the core. Seat depth is the adjustment most budget chairs skip and the one tall and short users notice most.
3. Materials for the seat and back
The two common choices are mesh and foam with upholstery. Mesh breathes and stays cooler, which many people prefer in warm climates and warm buildings. Foam feels softer and more cushioned. Neither is right for everyone.
- Mesh: should be evenly taut with no sagging, fraying or pulled strands at the frame edges.
- Foam: should spring back when you press it. Flattened foam feels hard after an hour.
- Upholstery: look at the front seat edge and armrest pads, which wear first. Commercial-grade fabric and vinyl clean up better than light residential fabrics.
4. Build quality and parts
This is where commercial chairs separate from inexpensive ones. Flip the chair over if you can.
- Base: a five-star base is standard for stability. Check for cracks where the legs meet the hub.
- Casters: hard casters roll on carpet, softer casters protect hard floors. Casters should spin freely.
- Cylinder and mechanism: listen for grinding or clunking when you recline and adjust.
- Replaceable parts: major manufacturers usually design chairs so arms, casters, cylinders and seat pans can be swapped. That extends the life of the chair.
- Stability: lean back fully and shift your weight side to side. A good chair feels planted.
5. New versus pre-owned, and the condition grade
The last question is where the chair comes from. A pre-owned chair from a commercial manufacturer was built for the same years of heavy use as a new one, and it often costs far less. The tradeoffs are selection, since you buy what is available, and warranty.
| Factor | New | Pre-owned from Office Station |
|---|---|---|
| Selection | Choose any color, size and option | Buy from what is in stock; matched sets depend on inventory |
| Warranty | Manufacturer warranty applies | Manufacturer warranties generally do not transfer |
| Condition | Unused | Graded A like new, B very good, or C good |
| Brands | Buy through an authorized dealer | Herman Miller, Steelcase, Knoll, Haworth, Humanscale, Teknion, Allsteel and others, sold by an independent reseller |
Office Station is an independent reseller, not an authorized dealer for any of these manufacturers. Use the grades to match chairs to the job:
- Grade A, like new: executive offices, client-facing areas and anyone who wants a chair that looks unused.
- Grade B, very good: everyday task seating for a team. Light signs of use, full function.
- Grade C, good: training rooms, overflow seating and budget-first rollouts. Visible wear, fully functional.
Quick checklist before you buy
- Seat height and depth fit your shortest and tallest users.
- Lumbar support lands on the lower back curve.
- Tilt tension, tilt lock and arms all work without instructions.
- Mesh is taut or foam springs back.
- Base, casters and cylinder show no cracks, grinding or sinking.
- You know whether a warranty applies and what the condition grade is.
If you are furnishing a whole team, chairs and workstations are easier to plan together. Browse pre-owned office furniture, look at used cubicles for the desks, or read more in the guides library.

Frequently asked questions
What is the most important thing to look for in an office chair?
Fit comes first. The seat height should let your feet rest flat with your thighs roughly level, and the seat depth should leave a gap of a few fingers between the seat edge and the back of your knees. A chair with every feature still fails if it does not fit the person using it.
Is a pre-owned designer chair better than a new budget chair?
It often is. A pre-owned chair from a major manufacturer was built for years of commercial use, and many models have replaceable parts. Check the condition grade, test the adjustments and remember that manufacturer warranties generally do not transfer to pre-owned chairs.
What do condition grades A, B and C mean?
At Office Station, Grade A means like new, Grade B means very good with light signs of use, and Grade C means good with visible wear but fully functional. Grade C chairs are often a smart choice for training rooms or overflow seating.
Does Office Station sell chairs as an authorized dealer?
No. Office Station is an independent reseller of pre-owned designer furniture, not an authorized dealer for any manufacturer. That is why manufacturer warranties generally do not carry over to pre-owned chairs.
Mesh or foam: which seat is better?
Neither is better for everyone. Mesh breathes and stays cooler, which many people prefer in warm offices. Foam with upholstery feels softer and more cushioned. Try both if you can, and check that mesh is taut and foam has not flattened.
