A piece of furniture with side supports for your arms is generally known as an armchair. While many styles exist, the defining feature is simply the presence of these armrests, which distinguish it from a standard side chair or a dining chair that lacks them.
Choosing the right chair depends mostly on how you plan to use it. If you need it for long periods of work, you should prioritize lumbar support and adjustable height, whereas a lounge chair is built for relaxation. The most common mistake people make is buying a chair without measuring their table or desk height first, which often leaves them unable to tuck the chair in properly.
What a chair with arms is called

- Measure the height of your table or desk from the floor to the underside of the surface.
- Check the distance between the floor and the top of the chair arms to ensure they will slide under the table without hitting the frame.
- Test the seat depth by sitting back and checking if you have about 2 inches of space between the edge of the seat and your knees.
- Adjust the seat height so your feet rest flat on the floor and your knees are at a 90-degree angle. Tip: If you’re buying a chair for a child, look for adjustable models, as these allow the furniture to grow with them.
- Confirm the material matches your environment; for example, wood is durable for high-traffic areas, while fabric offers more comfort for living rooms. Tip: Avoid light-colored fabrics in homes with pets, as these show stains and hair much faster than darker or patterned materials.
Understanding chair dimensions and fit
The time it takes to find the perfect piece depends on whether you’re buying off the shelf or ordering a custom design. Most retail furniture stores provide standardized dimensions based on ANSI/BIFMA office furniture standards to ensure safety and comfort for the average user.
| Situation | Time to find | What changes it | What to watch for |
|---|---|---|---|
| Retail shopping | 1-2 hours | Store inventory size | Available floor space |
| Custom order | 6-12 weeks | Material availability | Shipping delays |
| Online search | 30-60 minutes | Filter accuracy | Return policy terms |
If your search takes longer than expected, widen your search parameters to include different materials or finishes rather than sticking to one specific color.
Signs a chair fits your body

You can tell a chair is the right fit when your spine maintains its natural curve and your shoulders feel relaxed rather than hunched. Your feet should sit firmly on the ground, and your elbows should rest comfortably on the armrests at a 90-degree angle. If your arms are forced upward or you have to lean to reach the armrests, the chair is either too tall or too wide for your frame.
Common mistakes in chair selection

- Ignoring the armrest height: Many people buy chairs based on looks alone, only to find the arms catch on the edge of the desk. Always measure your desk clearance before purchasing any model with fixed armrests.
- Overlooking seat width: A chair that’s too narrow restricts your movement, while one that’s too wide prevents your arms from resting naturally. Choose a width that provides about 2 inches of space on either side of your hips.
- Neglecting back support: A chair that lacks proper lumbar support can lead to discomfort during long periods of sitting. If you find a chair you love that lacks this support, consider adding a small cushion to bridge the gap between your lower back and the chair.
Frequently asked questions
Can any chair with arms be called an armchair?
Yes, any chair that features side supports for your arms is technically an armchair. While specific styles like wingback, club, or recliners have unique names, they all fall under the broad category of armchairs because of their structural design.
Why do some chairs have shorter arms?
Short arms are often designed so the chair can slide completely under a desk or dining table. This design feature saves floor space and keeps the chair tucked away neatly when it isn’t in use, which is helpful in smaller rooms or tight office cubicles.
Is it safe to use a dining chair as an office chair?
No, it’s generally not recommended for long-term use because dining chairs lack the ergonomic adjustments of a dedicated office chair. Using a non-ergonomic chair for 8 hours a day can lead to poor posture and back strain, as they’re designed for short-term sitting during meals.
How much space do I need around an armchair?
You should allow at least 30 inches of clearance around an armchair to ensure you can get in and out easily. If the chair is a recliner, you need to account for the full extended length plus an extra 6 inches for walking space behind the footrest.
What happens if the arms are too high?
If the armrests are too high, your shoulders will be pushed upward, which causes neck and shoulder tension over time. You should look for a chair where your arms hang naturally and your elbows rest at a 90-degree angle without any shoulder elevation or discomfort.
How often should I replace my chair?
You should replace a chair when the padding no longer provides support or the frame shows signs of instability. Depending on the build quality and daily usage, a well-made chair typically lasts for a significant period, but you should check it annually for loose screws or worn-out foam.
Conclusion
Whether you’re looking for extra comfort in your living room or better support at your desk, these chairs make a big difference. Don’t be afraid to test a few different models in person before you buy. You’ll find that sitting in one for a few minutes is the best way to choose.
