Flip-up armrests rotate out of their normal working position, which can remove an obstruction at the desk edge. They do not make the whole chair smaller in every direction. Check the remaining hinge, seat, base and backrest in the raised-arm position before relying on under-desk storage.
At a glance
- Flip-up, removable and height-adjustable arms solve different problems. Check the exact mechanism.
- A raised arm can leave a hinge or support in the desk opening, and it needs room to rotate.
- A current product listing does not provide a complete chair-and-desk fit model. Measure the missing geometry.
What flip-up arms change
A flip-up armchair can work well when you want arm support while seated and a clearer side opening after work. You move the arms upward, store the chair, then return them to their normal position. The motion can avoid repeated disassembly.
The space saving depends on which part of the chair meets your desk. If the horizontal arm pads are the obstruction, rotating them may help. If the base hits a desk foot or the seat meets a low drawer, the arm movement may make little difference. The armrest height guide explains how to separate pad height from the desk’s clear underside height. A chair can have genuine flip-up arms without fully tucking underneath a particular desk.
Flip-up, adjustable and removable are different mechanisms
An armrest described as adjustable may move vertically, sideways or forward without rotating clear of the desk. Labels such as 2D, 3D or 5D summarize several adjustments; they do not consistently identify a flip-up motion across brands. Look for the specific action in the model description or instructions.
Removable arms are another option, but removing bolts is a different routine from operating a hinge. A foldable backrest is different again. Compare the feature that solves your measured obstruction, rather than collecting adjustment labels.

Scroll the table to compare all columns.
| Mechanism | What changes | What to check |
|---|---|---|
| Flip-up arms | Arms rotate toward an upright or rearward position. | Raised hinge/support height, rotation space and return motion. |

Three current US listings with true flip-up arms
These examples have current US product pages that explicitly describe a flip-up arm mechanism. The table is a starting point for comparison, rather than a ranking of comfort, durability or complete desk compatibility. Cart controls were present during the check; delivery and the exact selected variant still need confirmation.
Widths and depths below are listing-level overall dimensions in inches, not confirmed base diameters or raised-arm measurements. The B100 page offers different seat and footrest options without separately binding its general dimensions to each combination. Confirm the selected combination before relying on that envelope.
Flip-up office chair dimensions and remaining questions
Scroll the table to compare all columns.
| Model or listing | Listed overall width × depth | Mechanism confirmed | Missing for a storage decision |
|---|---|---|---|
| Techni Mobili RTA-8050-BK, Black | 24 3/4 × 24 1/4 | Built-in flip-up arms | Seat-height range; raised hinge height; caster envelope and rotation path. |
| Sihoo B100 US listing; seat and footrest options vary | 27.6 × 28.3; confirm selected combination | Flip-up 2D arms | Configuration-specific envelope; seat-height range; raised hardware height. |
| Sihoo M59AS US listing; Black or Gray options | 28 × 28 | Flip-up 3D arms | Seat-height range; raised hardware height; base/caster and recline envelope. |
How to read these examples
The RTA-8050-BK has the narrowest listed overall width in this three-model comparison. That is useful for an initial room sketch. It does not prove it has the narrowest base or that its raised arm bracket clears a drawer. Its overall height range of 39 1/4–43 inches is also different from a seat-height range.
The B100 and M59AS illustrate why the phrase “space saving” should lead to measurements. Both list overall widths around 28 inches. A flip-up mechanism may reduce interference near the desktop while leaving a substantial footprint on the floor.
The M59AS also has an integrated coat hanger. If you use it, check the bag or clothing against nearby furniture and the path behind the chair. Accessories added after a fit check can change how a small nook works.
Measure three chair states
First, set the chair for work with the arms down. Measure from the floor to the highest arm surface that approaches the desk. Check that the arm position also lets you reach the keyboard without raising your shoulders or reaching around a high pad.
Second, pull the chair clear of the desktop and move the arms through their normal rotation. Watch the highest and widest part of the movement. A wall, drawer handle or desk edge may block the motion even when the final raised position looks clear. Follow the model instructions and keep fingers away from the hinge.
Third, measure the intended stored position with the arms raised. Include the hinge, bracket, seat rim and any part of the backrest that travels beneath or near the desktop. If you lower the chair for storage, record that as a separate seat setting rather than mixing its height with your working configuration.
Check the desk along the complete route
The relevant height is the lowest obstruction under the desk, not the height of the desktop surface. A front drawer, apron, cable tray or rear rail can set the limit. Follow the complete clearance measuring process where the chair parts will travel, including any lower section that projects farther forward than the arm pad.
Width can change with height. Casters and star-base spokes pass near desk feet; the seat passes between legs or storage pedestals; raised arms may meet supports higher up. A single opening width at desktop height is rarely enough to describe every one of those routes.
Usable depth determines how much chair remains in the room. Measure from the front edge toward the first rear obstacle. Then decide where you want the seat or backrest to stop. The chair does not need to disappear completely to be useful, but the remaining projection must suit your walkway.
- Check vertical space at every point the hinge or seat enters.
- Check width at caster, base, seat and raised-arm height.
- Check the path needed to rotate the arms before insertion.
- Check depth to the first rear obstruction.
- Check that the stored chair leaves doors and drawers usable.
An example of a partial improvement
Consider a chair whose arms-down height is 27 inches and a desk with 25 inches of clear height. The arms obstruct a straight insertion path. If raising them leaves a bracket at 24 inches, the nominal height difference becomes one inch.
That result clears only the measured height comparison. A base wider than the leg opening can still stop the chair, and a rear brace can still limit depth. The example uses invented dimensions to show the method; it is not a compatibility claim for any chair listed here. Enter actual measurements in the fit tool and keep unknown dimensions open.
Choose a routine you will actually use
If you store the chair several times each day, try the complete sequence: pull back, rotate both arms, lower the seat if necessary, and roll in. Reverse it before sitting. Check that controls remain reachable and that neither arm is trapped under the desk when lowered.
If the sequence is awkward, an armless model may be simpler. If you want continuous arm support and rarely store the chair, height-adjustable arms with a suitable minimum height may be sufficient. The most useful mechanism is the one that works with your desk and normal tasks.
Confirm model, color, seat option, footrest option, return terms and assembly requirements before ordering. Photographs of a chair beneath a different desk show one arrangement; they do not supply the missing hinge, base or clearance dimensions for yours.
Frequently asked questions
Do flip-up arms mean the chair will fit under my desk?
No. They may remove the horizontal arm pad from the path, but a hinge, seat, backrest or base can still interfere. Measure the chair in its raised-arm state and check the complete desk opening.
Are removable arms the same as flip-up arms?
No. Flip-up arms operate on a hinge. Removable arms change the assembled configuration when the model allows it. A removable arm should not be described as a daily flip-up feature.
Can I use the overall chair height to check desk clearance?
Overall height usually reaches the top of the backrest or headrest. For an underside check, measure the specific part entering the opening at the seat and arm setting you will use.
What if the manufacturer does not give raised-arm dimensions?
Treat that geometry as unknown. Ask for the floor-to-highest-hinge measurement at the intended seat setting, plus raised width and rotation space. Without it, a product photo cannot establish a complete fit.
Should the arms be raised before I push the chair in?
Follow the exact chair instructions. Check the arm rotation while the chair is clear of nearby furniture, then test the intended path gently. Do not force a pad or hinge against the desk.
