Get arms if you type or use a mouse for hours and your desk lets you pull the chair close. Skip them, or choose flip-up arms, if your desk is low or narrow, if you get in and out of the chair all day, or if you want the chair to slide fully under the desk. Arms are optional: the U.S. Occupational Safety and Health Administration (OSHA) says using an armrest is a personal choice, and that if they cannot be adjusted or get in the way, you should remove them or stop using them (OSHA chair guidance).
This guide compares four types, shows what each one costs you in floor and desk space, and includes a quick check for whether arms will fit under your desk.
Quick answer by situation
| Your situation | Better choice | Why |
|---|---|---|
| Typing or mouse work for hours | Adjustable arms | They can support your lower arms so your upper arms stay close to your body |
| Desk is low or has a drawer or apron at the front | Armless or flip-up | Fixed arms can stop the chair from reaching the desk |
| Chair must tuck away in a small room | Armless | Nothing to catch on the desk, and the chair is narrower |
| You turn, reach and stand up often | Armless or flip-up | Arms are one more thing to bump into or lean on awkwardly |
| Several people share the chair | Armless or fully adjustable arms | Arm height that suits one person can be wrong for another |
The four types compared
Fixed arms
Arms that do not move are the simplest and often the widest. They only work if their height happens to match your elbows. If they sit too high, your shoulders lift. If they are too low, they give no support. They also usually cannot slide under a desk.
Adjustable arms
These move up and down, and some also pivot or slide sideways. OSHA says armrests should be low enough that your shoulders stay relaxed and high enough to support your lower arms when they rest comfortably at your sides, and suggests adjusting them so they just make contact with the lower arms. They cost more floor width than armless chairs and still may not fit under the desk.
Flip-up arms
Flip-up arms rotate up and out of the way so the chair can slide under the desk. They are a compromise for small rooms. The listing rarely says how much you can adjust the height, so check whether the arms only flip or also adjust.
Armless
An armless chair is narrower, tucks under any desk with enough knee room, and lets you turn freely. You lose forearm support, which matters more for long typing sessions than for short ones.
Will the arms fit under your desk?
Arm clearance check
Measure your desk height from the floor to the top of the desk, the thickness of the desktop (including any front apron), and the height of the chair’s armrests from the floor at their lowest setting.
Simple subtraction. Drawer rails, keyboard trays and crossbars can reduce the space, so try the real chair when you can.
Who should choose what
- Long keyboard-and-mouse days at a desk with an open front: adjustable arms, set so your shoulders stay relaxed.
- A small desk or a laptop on a low table: armless or flip-up. See our armless chair picks for compact options.
- Drawing, sewing or tasks that need wide arm movement: armless, so nothing blocks your reach.
- Mixed use, such as work plus dining or a vanity: flip-up arms, or armless if the chair is shared.
- A dedicated single-person workstation: adjustable arms, provided your desk height also suits you. Use the desk height calculator to check.
Common mistakes
- Buying arms without measuring the desk underside, then finding the chair stops 10 inches from the desk.
- Keeping arms too high. If your shoulders lift, lower the arms or remove them.
- Assuming flip-up means adjustable. Some only fold.
- Choosing arms for looks and never using them. OSHA says removing arms that get in the way is acceptable.
- Ignoring the chair width, which arms can add to. Our chair fit checker explains how to compare chair and desk clearance.
Products worth checking
These products match the topic above. We have not tested them. Sizes and features come from the Amazon listings, checked on September 30, 2026; where a listing does not say, we say so.
Sweetcrispy Small Armless Desk Chair
This is a compact, low-back chair with a PU leather seat and back cushion, a height-adjustable base and a 360-degree swivel. The listing presents it for bedrooms, vanities and small workspaces.
- Good for: tight nooks, a vanity or dressing table, and short work sessions.
- Keep in mind: it is a small, low-back design, so it is a better fit for lighter use than for long, all-day work. Check the seat height range against your desk.
NEO CHAIR Ergonomic Mesh Chair with Flip-Up Armrests
The listing describes an elastic mesh back with a contoured shape, padded arms that flip up to fit under desks, adjustable seat height and tilt tension, and a 360-degree swivel with a wide, balanced base.
- Good for: daily work in a small space where you want arms sometimes and a smaller footprint at other times.
- Keep in mind: at 22 x 23.5 x 40 inches it is a large chair for a small room, so measure your desk opening and the space behind it.
Marsail Ergonomic Office Chair: clearest lumbar range with flip-up arms
The listing gives a lumbar that moves 1.18 inches forward and back and 2.16 inches up and down, a 2D headrest, a 90 to 120 degree recline, 3D armrests that flip up, a 3.14 inch high-density foam seat and a 330 lb rating.
- Good for: someone who wants a stated lumbar range and arms that flip up under a desk.
- Keep in mind: the headrest moves in two ways only, and the user height range is not stated.
Frequently asked questions
Are office chair arms necessary?
No. OSHA says using an armrest is up to the user. They help some people rest their lower arms, and they are optional.
Are armless chairs bad for your back?
Not by themselves. Back support comes from the backrest and how the chair is adjusted. Armless chairs give up forearm support, which some people miss after long typing sessions.
What are flip-up arms good for?
They let you slide the chair under the desk when you do not need arm support, which saves floor space in small rooms.
How high should armrests be?
OSHA suggests they should just make contact with your lower arms when your arms hang comfortably at your sides, low enough that your shoulders stay relaxed.
Can I remove the arms from my chair?
Some chairs allow it and some do not. Check the manufacturer’s instructions before removing them.
