Xallking X5 Pro Review: Who Is This Chair Actually Built For

The Xallking X5 Pro is not built for everyone. That is the first thing to know.

It is built for Australian gamers who sit long, run warm, and want a chair that holds up over years, not months. The dual C-shaped lumbar, the 6D armrests, and the 3-zone backrest are not features added to a list. They are specific answers to specific problems. If those problems are yours, this chair will feel like it was made for you. If they are not, there are better options in the Xallking range and we will tell you what they are.

This review draws on the full verified spec sheet from our product sheet, accurate dimensions, and the ergonomic principles Xallking Australia applies across its range. The X5 Pro is a premium ergonomic gaming chair built for long sessions, and this review covers what it does well, where it falls short, who it suits, and who should look elsewhere. No padding. Just what you need to make the right call at this price point.

The X5 Pro at a Glance: Full Spec Sheet

Every number below comes from the official Xallking Australia and SIHOO Australia product documentation. Nothing estimated. Nothing assumed.

 

Note on availability:  The X5 Pro is sold under two labels: Xallking Australia and SIHOO Australia. Both are the same chair through different distribution channels. The SIHOO version is available at JB Hi-Fi nationally. The Xallking version ships direct from xallking.com.au. This comes up in online forums and it deserves a straight answer rather than a footnote. 

The Lumbar System: Where the X5 Pro Makes Its Strongest Argument

Lumbar support is where chairs in this price bracket either earn their place or get found out. The X5 Pro earns it.

The dual C-shaped design and what it actually does

Most gaming chairs under $1,000 AUD use a detachable lumbar pillow. That is not a design choice. It is a manufacturing shortcut. The pillow slides out mid-session, compresses within months, and fits a 170cm person and a 160cm person the same way. Which is to say imprecisely for at least one of them.

The X5 Pro uses an integrated dual C-shaped wrap system built into the chair structure. The dual C shape wraps around the waist muscles on both sides rather than pressing into one point on the lower back. The contact area is wider, the pressure is more evenly distributed, and that dull ache that builds after hour two in a single-point system becomes far less likely.

The 5cm vertical adjustment matters just as much. Lumbar support only works at the right height for your specific body. A fixed system cannot accommodate the range of lower back positions across people from 150 to 190cm. The adjustability is not a premium add-on. It is what makes the system work as described.

Ergonomic note:  Integrated adjustable lumbar support reduces erector spinae muscle activation during prolonged sitting. Less activation means less fatigue. This is the most directly evidence-supported feature in the X5 Pro design. 

Where the lumbar system has limits

The dual C-shaped system works best at a recline angle between 100 and 130 degrees. If you sit upright for work and then recline for gaming, the lumbar needs a quick readjust between modes. Minor inconvenience, but worth knowing if you expect a set-and-forget experience.

For gamers under 160cm or over 185cm, the adjustment range covers most positions but may not centre perfectly at the height extremes. If you sit at either end, check the full dimension matrix on the SIHOO Australia product page against your measurements before buying.

The 6D Armrests: What the Spec Means in Practice

6D armrests appear on a lot of spec sheets right now. What they actually deliver varies considerably. Here is exactly what the X5 Pro system covers and why each axis matters. 

Breaking down the six axes

Height spans 90mm, which is enough for the desk heights and body proportions the chair is sized for. Get this right and your shoulders drop. That release of tension across the upper trapezius is the difference between finishing a four-hour session feeling fine and finishing it with a neck that needs twenty minutes to unknot.

Tilt spans 35 degrees inward or outward. This is useful if you use a wide mouse grip or rest your forearms rather than your wrists. Most people set it once and never touch it again, which is exactly how a good adjustment should work.

Depth spans 50mm fore and aft. When you recline, your body shifts relative to the armrest. A fixed-depth armrest becomes useless at that point because your arms are no longer where the pad is. The X5 Pro moves with you.

Rotation spans 75 degrees and lateral movement covers 80mm. These two axes together handle the body width variation across 150 to 190cm, which is more significant than most people account for when buying a chair online without sitting in it first.

All six axes also move in sync with the backrest recline. Lean back and the armrests follow. It sounds like a baseline feature. Most chairs at this price do not include it.

Who benefits most from the full 6D range

The full 6D range pays off most for gamers who move between modes across a session: upright for work, forward for competitive play, and reclined for watching replays. Each position benefits from a different armrest configuration. If you stay in one position for your entire session, a 4D system at a lower price point gets you most of the way there. 

The 3-Zone Elastic Backrest: The Feature Most Reviews Underexplain

The backrest appears in every spec list. It rarely gets explained. That is a problem because it is one of the more interesting engineering decisions in the chair.

What three zones means structurally

A standard gaming chair backrest is a single panel. It supports whatever part of your back is in contact with it. Shift position and the contact point changes, but the support does not adapt. You simply find a new part of your back that is unsupported.

The X5 Pro backrest divides into three independent zones: upper, mid, and lower back. Each zone uses aerospace-grade glass fibre elastic plates that flex independently. When you lean back, the upper zone flexes to accommodate your shoulder blades without pressing into them. When the lower back curves inward, the lower zone follows that curve without the mid zone resisting it. This kind of independent flex is straightforward in principle and surprisingly rare at this price point.

The result is a backrest that follows your shape across positions rather than one you have to stay locked into. The research is clear on this: postural variety during a session is better for your spine than holding one position for hours, even a correct one. A backrest that moves with you supports that variety. One that does not works against it.

The saddle-type seat cushion

The seat cushion does not get much attention in reviews. It should. The saddle-type pressure-dividing design spreads body weight across a wider contact area than a flat foam cushion, which reduces peak pressure under the sit bones. For sessions over three hours, this is the difference between a chair that stays comfortable and one that creates that specific soreness that makes you shift every fifteen minutes without knowing why.

The seat depth adjusts from 40 to 47cm, which is worth noting. A seat that is too deep for your leg length pushes you forward and away from the lumbar support. When that happens, the entire ergonomic system stops working. Adjustable depth keeps the contact point where it needs to be for your leg length. The chair fits you. You do not have to fit the chair.

How the X5 Pro Performs in Australian Conditions

Most chair reviews are written for temperate climates. This one is not. Australian gaming rooms without active cooling regularly hit 30 to 35 degrees in summer. That changes how you evaluate a chair.

Breathability and the Australian heat question

The X5 Pro uses polyester elastic mesh across the backrest and seat contact areas. Air moves through the weave. In a room pushing 30 to 35 degrees during an Australian summer session, that is not a comfort feature. It is what keeps the chair ergonomically functional through the full session.

When a chair traps heat, the response is predictable. You sweat, you shift, and you adjust. Not because you want postural variety but because you are uncomfortable and looking for relief. That reactive movement undermines the lumbar support and posture alignment the chair is built to provide. Breathability delays that breakdown. It does not eliminate it in extreme heat without airflow, but it extends your effective sitting time in Australian conditions significantly compared to PU leather or solid synthetic alternatives at the same price point.

Floor compatibility and noise

The silent PU castors work on timber, tile, and carpet without marking surfaces. In an Australian apartment or rental property, that matters more than most reviews acknowledge. The TUV/SGS certified gas lift provides smooth height adjustment without the slow drift that cheaper lifts develop after six months of daily use. Small details. Meaningful over time.

Where the X5 Pro Has Limitations

This is where the review stops being enthusiastic and starts being useful.

The recline preset system is not fully continuous

The recline locks at three positions: 100, 110, and 130 degrees. A free recline extends to 138 degrees. For most gaming postures, 100 and 110 degrees cover the range where you will spend your time. If you prefer something closer to 120 degrees, you will use the free recline and hold it rather than locking in. Minor limitation, but noticeable if you are precise about your sitting angle.

The aesthetic is not for everyone

The X5 Pro looks like a serious chair, not a statement one. The design is clean and modern rather than aggressive. If your setup has a strong visual identity and you need the chair to anchor it, the X3 PRO is the better option. The X5 Pro outperforms the X3 PRO on ergonomics in several areas. It does not on visual presence. Choose based on what you actually need the chair to do.

Assembly requires patience

Assembly takes 45 to 60 minutes the first time. The instructions are clear and the process is logical. The most common problems come from the 6D armrest mechanism and the aluminium base, both of which need careful alignment during installation. Rush either and you get armrest wobble that is difficult to correct without partially disassembling the chair. Set aside a full hour. Do not attempt it between meetings.

The price point requires justification

At $799 AUD street price, the X5 Pro sits in a bracket where honest comparisons become uncomfortable. Second-hand Herman Miller Aerons exist in that range. So do mid-tier Ergotrons. The case for the X5 Pro is specific: a gaming recline range, integrated adjustable lumbar, 6D armrests, and breathable mesh built for Australian summers. If those four things match your needs, $799 is justified. If you sit upright all day in a cool room and game for an hour on weekends, a quality office chair at the same price will likely serve you better. We would rather say that clearly than sell you the wrong chair.

Straight answer:  The X5 Pro is worth the price if you game for more than two hours a day in a warm room and want ergonomics that adjust to your body. It is not worth it if you sit upright, game occasionally, and your room stays cool. 

Who the X5 Pro Is Actually Built For

This is the question the review was built around. Here is the actual answer.

The X5 Pro is built for

• Gamers who play for two or more hours at a stretch and experience back or neck pain in their current chair
• Australian gamers in rooms that get warm in summer and need breathable materials to maintain comfort and posture through a full session
• People who use the same chair for work and gaming and need it to perform well in both an upright and a reclined position
• Gamers between 160 and 185cm where the lumbar and armrest adjustments deliver the most consistent fit
• Streamers and content creators who spend four or more hours at a desk and need a chair that holds them correctly on camera without causing fatigue
• People who want a chair that lasts: the aluminium base, glass fibre backrest plates, and TUV/SGS certified gas lift are all built for daily use over years

The X5 Pro is probably not right for

• Gamers under 160cm or over 185cm who may find the lumbar range does not centre perfectly at the height extremes. The X5C or X5F may offer a better fit
• Gamers who want a bold visual statement in their setup. The X3 PRO is the better choice for aesthetics-first builds
• Casual gamers who sit for under an hour at a time. The ergonomic investment is not necessary for short sessions
• Buyers with a strict budget under $500 AUD. The X5S or X5C are stronger entry points into the Xallking range without the full 6D armrest specification

The Verdict

Nine dimensions. No hedging.

The X5 Pro is one of the more honestly built chairs available in Australia at this price point. It does what the spec sheet says it does. Whether that matches what you actually need is the question this review was built to answer.

The Bottom Line

The Xallking X5 Pro is built around specific decisions, not a checklist of features. It is a coherent system designed for a specific kind of person in a specific kind of environment.

That person games for two or more hours at a time. They run warm. They use the same chair for work and gaming. They sit somewhere between 160 and 185cm and they are done fighting a lumbar pillow that slides out every hour. They want ergonomics that work, not

 ergonomics they have to maintain.

If that is you, the X5 Pro is a serious chair at a justifiable price. If it is not, Xallking Australia's full range has options built for different profiles. The right chair is the one built for the person sitting in it.

Know what you need. Buy the chair that was built for exactly that.
