Four beats three, apparently.
That's how the spec sheets read, and it's how most people shop. More locks, better chair. So you pay the difference, get the chair home, and end up using two of the four positions for the next three years.
The count is the wrong thing to compare, though. Where the locks sit decides whether you use them, and a chair with three well spaced positions can serve you better than one with four bunched at the wrong end.
Here is how to work out which angles you need before the Click Frenzy Sale, and how the lock positions fall across our ergonomic gaming chair range.
Recline Range and Lock Positions Are Not the Same Thing
Recline range is the arc the backrest travels through. Lock positions are the stops inside that arc where the mechanism holds.
A chair listed at 107 to 135 degrees gives you a 28 degree arc. Whether you can stop anywhere inside it, or only at two or three preset points, is a separate question the range figure never answers.
Both matter, and they answer different needs. Range decides how far you can lean. Locks decide whether the chair holds you there without you bracing against the backrest.
So when you compare two models, read both numbers. A wide range with no usable stop in the middle leaves you either upright or lying down.
What Each Angle Is Actually For
Degrees mean nothing until you map them onto what you actually do. Here is the map we use when someone asks us which chair suits them.
|
Angle band |
What it suits |
What happens if you sit here too long |
|---|---|---|
|
95 to 105 degrees |
Typing, competitive aim, anything needing precision |
Upright loads the lower back. Fine for stretches, tiring all day |
|
105 to 115 degrees |
General desk gaming, browsing, study |
The most usable band for most people at a desk |
|
115 to 125 degrees |
Controller play, watching a stream, voice calls |
You drift away from the keyboard without noticing |
|
125 to 135 degrees |
Cutscenes, breaks, reading on a phone |
Neck flexes forward to keep a screen in view |
|
135 degrees and past |
Resting, napping between sessions |
Not a working posture. Treat it as a break position |
Most people live in the 105 to 125 band and visit the deep end a few times a week. So a chair needs a stop somewhere around 118 to 122 degrees more than it needs a fourth position at 145.

Where the Gaps Fall on Each Xallking Chair
Here are the published lock positions across the gaming chair range, with the size of each gap worked out. The gaps are the part nobody prints.
|
Model |
Lock positions |
Gaps between locks |
Where it leaves you |
|---|---|---|---|
|
X5C |
107 to 135, continuous |
No fixed stops |
Stop anywhere, but you hold it with body weight |
|
X5F |
110, 122, 135 |
12 and 13 degrees |
Even spacing across the working band |
|
X5 Pro |
95, 125, 138 |
30 and 13 degrees |
A wide hole between upright and relaxed |
|
X5S |
108, 118, 128, 140 |
10, 10 and 12 degrees |
Three stops inside the band most people use |
|
X3 Pro |
98, 108, 130, 145 |
10, 22 and 15 degrees |
Two upright stops, then a jump past the relaxed band |
Read that table and our pricing stops making obvious sense, which is exactly why we're publishing it.
The X5S has four evenly spaced locks and three of them sit inside the 105 to 130 band where desk gaming happens. For someone who works and plays at the same desk, that spread is hard to beat, and it's the cheapest chair we make.
The X3 Pro has four locks too, but two of them sit at 98 and 108 degrees, then the mechanism jumps straight to 130. If you like sitting at around 120 with a controller, the X3 Pro won't hold you there. You buy it for the 145 degree position and the lumbar system, not for mid range spacing.
The X5 Pro carries the widest single gap in the range at 30 degrees. It suits someone who works upright and then relaxes properly, rather than someone who drifts through every angle in between.
Does Free Rocking Replace a Lock?
It doesn't, and the reason is muscular rather than mechanical.
With the lever released, the backrest follows you and the tilt tension pushes back. Holding a position means your body keeps supplying pressure, so your trunk and hip flexors stay lightly engaged the whole time. Over twenty minutes you stop noticing. Over three hours you feel it.
A lock removes that job. The mechanism holds the angle and your muscles let go, which is the whole reason the feature exists.
Free rocking still earns its place for short bursts and for movement through a long session, and every chair in our range lets you release the lever and rock. Use it as variation rather than as a substitute for a stop.
Why Linked Armrests Change the Maths
Every chair in our range carries linked recline armrests. The arms follow the backrest as it drops rather than staying fixed to the seat.
That sounds like a detail until you change angle, and then it isn't. On a chair with fixed arms, leaning back leaves your forearms behind, so your shoulders take the weight and you end up reaching for the desk. On a linked chair the arms travel with you and the support holds through the lean.
The practical effect is that a linked chair makes more of its lock positions usable. You can sit at 128 degrees and still rest your arms, which means the deep locks stop being break positions and start being places you can play from.
The X5 Pro and X3 Pro pair linked recline with 6D armrests, so the arms also slide and pivot once they arrive. The X5S and X5F use 4D. Both are linked, which is the part that matters here.

The Stability Test
A lock is only worth having if it holds. Run this on any chair you can sit in before you buy.
-
Set the chair to its middle lock and sit back fully.
-
Push into the backrest with about half your weight, then release. The backrest should not creep further back.
-
Shift your weight to one side. The frame should not twist or click.
-
Stand up and sit down again without touching the lever. The angle should still be where you left it.
-
Listen. A lock that clicks under load is riding on a worn detent rather than seating properly.
Buying online instead? Check the tension knob under the seat when the chair arrives and run the same test. A lock that creeps is almost always a tension setting rather than a fault, and winding the knob in a few turns fixes it.
Who Actually Needs Four Locks
Fewer people than buy them, frankly. Four positions earn their money in three situations.
You switch between distinct activities at the same desk. Keyboard work at 108, controller at 118, a stream at 128. Three separate postures in an evening, each wanting a stop.
You share the chair. Two people with different heights and different habits need more places to land than one person does.
You use the chair for breaks as well as sessions. A deep lock turns a chair into somewhere to rest for twenty minutes, which matters more in a bedroom setup than in a dedicated office.
If none of those describe you, three well spaced locks will serve you for years, and the money is better spent on seat height range or armrest travel.
There is a fourth case worth naming, and it is the one people bring up least. If you have a desk job and then game at the same desk in the evening, you are asking one chair to hold two different postures across ten hours. A stop for each one is worth paying for, and it is the clearest argument for four positions we hear.
Shared household chairs are the quiet fourth case. A chair in a lounge room gets used by whoever sits in it, and preset stops mean nobody has to learn a tension knob to get comfortable.
When Lock Spacing Stops Mattering
Lock spacing matters less than it sounds in two cases.
If you sit upright to compete and never lean back, buy on armrest adjustability and seat depth instead. A single upright lock is all you'll touch.
If your room cannot clear a deep recline, the deepest lock is decoration. Measure the space behind your chair first, because a 145 degree position you can't reach adds nothing.
And if lower back discomfort is what sent you looking, changing angle through the day may reduce pressure and help you hold a more neutral position. A chair is not a treatment though, and we are not about to suggest otherwise. Book in with a physiotherapist or your GP.

Taking It to the Click Frenzy Sale
Work out the two or three angles you actually sit at, then find the chair with stops near them. For most Australian desks that means a lock near 110 and another near 120, which the Click Frenzy Sale covers at the X5S price point.
Prefer the deep end as well? The X3 Pro reaches 145 degrees. Buy it for that position and for the lumbar system rather than for the count on the spec sheet, because its middle spacing is wider than the X5S. Every model ships free across Australia with a 3-year warranty and 30-day returns.
One last piece of arithmetic before you choose. Count how many of a chair\u2019s locks fall inside the band you mapped earlier. The X5S puts three of four inside 105 to 130 degrees. The X3 Pro puts two of four there. That ratio predicts day to day comfort better than the total ever will.
Conclusion
Manufacturers print the number of locks because it is easy to compare. Where those locks sit is harder to fit in a bullet point, and it's the part that decides whether you use them.
Map your own angles first. Desk work, controller, break. Then find the chair with a stop near each one.
Twelve years into building gaming seating, we would sooner point you at the cheapest chair in the range for its mid band spacing than talk you into a fourth lock you will never reach for.
