Xallking X5C Review: The Breathable Gaming Chair Built for Australian Conditions

The Xallking X5C is not trying to be the X5 Pro. That matters to state upfront because too many chair reviews evaluate a product against the flagship rather than against the actual question: does this chair do what it was built to do?

What the X5C was built to do is specific. It was built for Australian gamers who need full breathable mesh construction in a gaming chair, who sit at the lower end of the height range, and who want genuine ergonomic support without the full premium specification and price of the X5 Pro. It sells for $559 AUD. That is the bracket where most Australian families and individual buyers are actually making their gaming chair decisions.

This review is built on the verified spec sheet from the Xallking Australia product page, direct ergonomic assessment of each specification, and honest comparison with the other chairs in the Xallking range. It covers what the X5C does well, where it has real limitations, and who should buy it. An ergonomic gaming chair at this price point earns its place by being the right chair for the right person — not by pretending to be something it is not.

The X5C at a Glance: Full Verified Spec Sheet

Every number below is pulled directly from the live Xallking AU product page.

Spec note:  The seat depth is fixed at 51cm with no adjustment. This is the most important spec to check against your leg length before purchasing. If you need depth adjustment, the X5 Pro is the right choice.

The Breathable Mesh: Where the X5C Makes Its Case for Australian Conditions

The X5C's headline feature is not its price. It is the mesh construction. And for most Australian gamers, this is the feature that makes the strongest argument for the chair.

What the X5C mesh actually delivers

The mesh specification is listed as elastic, breathable, oilproof, and pressure-resistant. These are not marketing terms for this material — they describe real structural properties. Elastic mesh maintains tension without sagging under sustained load. Breathable means air moves through the weave rather than being blocked by the surface. Oilproof means the mesh resists degradation from skin contact over time. Pressure-resistant means the material distributes contact force rather than concentrating it at fixed points.

In practice, across a three or four-hour gaming session in an Australian summer room, the effect is consistent with what the construction suggests. The contact surface stays cooler than a sealed PU leather or synthetic chair because the body heat has somewhere to go. Perspiration evaporates rather than building up. The thermal load that drives the reactive postural shifting documented in hot environments is reduced.

Australia's east coast gaming rooms regularly sit at 28 to 32 degrees during summer evening sessions without active cooling. The research on thermal comfort and gaming performance is consistent: performance degradation begins above 21 degrees, and the chair material is one of the top three factors affecting how quickly that degradation sets in. For the full comparison of how mesh and PU leather behave under AU conditions, see mesh vs PU leather gaming chairs: the Australian climate makes this an easy call.

The suspension system underneath the mesh

The mesh sits over a suspension system, which is worth noting because it changes how the mesh functions. Without a suspension system, mesh can bottom out under load and lose its postural support properties. The X5C's suspension system maintains the mesh tension at a consistent level across different sitting positions and body weights within the rated range. This is what the SIHOO AU product page describes as the chair being able to handle 40-degree days and 10-hour gaming sessions — the combination of breathable surface and maintained tension through the session.

The Quadruple Back Lumbar: What It Is and What It Is Not

The lumbar system is where the X5C differs most meaningfully from the X5 Pro, and where an honest review needs to be specific rather than vague.

What quadruple back means

The X5C uses a lumbar system described as quadruple back, with 4cm of vertical adjustment. The quadruple back design refers to a lumbar mechanism that contacts the spine across four distinct support zones rather than a single point or a simple C-shape. This distributes lumbar support across a wider area of the lower back, which reduces the localised pressure that makes single-point systems uncomfortable over time.

The 4cm vertical adjustment range allows the support to be positioned at the right height for different body proportions within the chair's height range. For most users between 160 and 185cm, this range is sufficient to find the position where the support sits at the natural inward curve of the lower back.

How it compares to the X5 Pro lumbar

The X5 Pro uses a dual C-shaped integrated system with 5cm of vertical adjustment, which wraps around the waist muscles on both sides rather than pressing into the back from a single direction. The X5 Pro's system is more precisely targeted for the waist musculature and has a slightly larger adjustment range.

The X5C's quadruple back system is genuinely functional lumbar support — not a pillow, not a vestigial cushion. It is integrated into the chair structure, it adjusts to the user's height, and it maintains contact through the recline range. For the majority of gaming and study sessions at 107 to 135 degrees, it provides adequate support. For users with very specific lumbar requirements or those who sit outside the mainstream of the chair's height range, the X5 Pro's more targeted system is the better choice.

The honest comparison:  X5C lumbar — functional, adjustable, wide contact area, 4cm range. X5 Pro lumbar — more precisely targeted, wraps the waist, 5cm range. Both are integrated systems. Neither is a pillow.

The Seat Height Advantage: Why 42.5cm Matters

The X5C has the lowest minimum seat height in the Xallking range at 42.5cm. This is not a small detail. For Australian gamers under roughly 165cm, seat height is the specification that determines whether a chair can actually be configured correctly for their body or whether they end up with dangling feet and a misaligned pelvis regardless of how good the rest of the chair is.

What the 42.5cm minimum delivers

At 42.5cm minimum seat height, the X5C can accommodate most users around 150 to 160cm with feet flat on the floor and knees at approximately 90 degrees. This is the foundational position from which every other ergonomic adjustment operates. A chair that cannot achieve this position for a shorter user cannot deliver its lumbar support, its armrest positioning, or its postural benefits correctly — because the entire system breaks down from the base upward when the feet cannot land correctly.

The X5S is the same price and also has a low seat height starting at 42.5cm. The difference is that the X5C adds the full breathable mesh construction that the X5S does not carry. For shorter Australian gamers who also need the thermal performance of mesh for summer sessions, the X5C is the chair in the range that satisfies both requirements simultaneously. For the full guide on what shorter Australian gamers need from a chair, see the best gaming chair for small people in Australia.

The fixed seat depth limitation at 51cm

This is the most significant limitation of the X5C and it connects directly to the seat height advantage. The seat depth is fixed at 51cm with no adjustment. For users between 165 and 185cm, this depth is appropriate. For users closer to 150cm, a 51cm seat depth may push the knees forward past the seat edge, which means the user tends to perch forward to achieve the correct knee position. When perching forward, the lower back loses contact with the lumbar support.

This is not a reason to avoid the X5C for shorter users. It is a reason to be specific about which shorter users the chair suits. A user at 155cm with longer legs relative to their torso will likely manage the 51cm depth without issue. A user at 152cm with shorter legs may find they need to sit slightly forward of the full seat depth to keep their knees from pressing against the front edge. In that case, the lumbar support needs to be extended forward slightly from its rearmost position to maintain contact.

If adjustable seat depth is a firm requirement, the X5 Pro's 40 to 47cm adjustable range is the right choice at a higher price point.

The Armrests: Functional but Not 6D

The X5C armrests cover three dimensions: height adjustment (7cm), depth adjustment (6cm fore-aft), and lateral adjustment (35cm inward-outward). They also link with the recline, meaning they follow the body angle when the chair reclines rather than staying fixed.

What the 3D range delivers

For most gaming and study use cases, height and depth adjustment cover the primary requirements. Height sets the correct elbow angle for shoulder relaxation. Depth accommodates the forward-backward shift between upright work and reclined gaming positions. The lateral movement allows the armrests to be positioned for different shoulder widths across the 150 to 190cm height range.

The linked recline is an underrated feature at this price point. When the chair reclines, the armrests move with the body rather than staying flat. This means the forearm continues to rest on the pad at the correct relative angle through the full recline range, rather than the armrests becoming useless below the elbow as the body angle changes.

What is missing vs the X5 Pro

The X5 Pro's 6D bionic joint armrests additionally offer tilt (35 degrees inward-outward of the pad surface), rotation (75 degrees), and a more precisely engineered joint mechanism at the armrest base. For competitive gaming where armrest position directly affects shoulder tension and arm movement consistency, the additional axes of the X5 Pro system matter. For gaming, study, and general long-session use, the X5C's 3D system covers the adjustments most users actually need.

The 107 to 135 Degree Recline: Built for Gaming Posture

The X5C reclines from 107 to 135 degrees. Research on lumbar disc pressure supports 100 to 135 degrees as the range that reduces spinal loading compared to upright sitting at 90 degrees. The X5C's recline range sits entirely within the ergonomically supported zone for gaming posture.

How the recline mechanism works

The recline uses a third-gear controller mechanism, meaning it locks at multiple preset positions across the range rather than requiring the user to hold a free recline. This is the correct mechanism for a chair used for both study and gaming — study position can be set and locked, gaming position can be set and locked, and the transition between the two is quick and deliberate rather than requiring the user to hold their own position.

The 107-degree minimum

The minimum recline of 107 degrees is worth noting for users who prefer a very upright sitting position for focused work. The X5C does not lock at 90 degrees. For users who regularly need to sit fully upright for focused study or professional work, the 107-degree minimum may feel slightly too reclined. For the majority of gaming and general use sessions, 107 degrees sits comfortably within the range where lumbar disc pressure is well-managed.

Who the X5C Is Actually Built For

The X5C is not a universal recommendation. It is the right chair for a specific profile of Australian gamer.

The X5C is built for

• Australian gamers who game in warm rooms without consistent active cooling and need breathable mesh to maintain thermal comfort and posture through a full summer session
• Gamers and students between 150 and 165cm where the 42.5cm minimum seat height delivers the correct seated foundation that most adult gaming chairs cannot reach
• Buyers who want genuine integrated lumbar support and mesh construction at $559 AUD rather than a PU leather chair with a pillow
• Gamers who use their chair for both gaming and study and need a recline range that covers both without the full 6D armrest specification of the X5 Pro
• Teenagers at the older end of the secondary school range (16 to 18) who have reached close to adult proportions and need a chair that handles the daily study and gaming load

The X5C is probably not right for

• Users who need adjustable seat depth — the fixed 51cm will not suit everyone under 160cm depending on their leg-to-torso proportions
• Gamers who want a fully locked 90-degree upright position — the 107-degree minimum may feel too reclined for focused work
• Competitive gamers who need the full 6D armrest specification for shoulder tension management and aim consistency during long ranked sessions
• Users above 185cm who may find the lumbar adjustment range does not centre perfectly at their lower back height

The Verdict

Nine dimensions. Honest assessment.

The Bottom Line

The X5C is a specific answer to a specific Australian problem. Hot rooms. Summer sessions. A budget that cannot stretch to the X5 Pro. A body that benefits from the lowest seat height in the range.

It does not have the 6D armrests or the adjustable seat depth of the X5 Pro. Anyone who needs those features should buy the X5 Pro. The X5C is honest about what it is: a well-built breathable mesh chair with functional integrated lumbar support, the right seat height for shorter Australian gamers, and a price that makes the ergonomic argument accessible to a broader part of the market.

The fixed seat depth is the one limitation that requires a measurement check before purchasing. Everything else delivers what the spec sheet says it delivers, which is the basic standard any chair at this price should meet and the one too many chairs at this price do not.

Browse the full Xallking gaming chair range to compare the X5C against the rest of the range. If breathable mesh for Australian conditions at $559 AUD is what you need, this is the chair.

Not every chair needs to be the flagship. The X5C knows exactly what it is.
