The AKRacing Opal gets a lot of hype for long workdays. High-back, reclining, good foam. Sounds like a steal at under $400. But before I clicked buy, I was already suspicious — because I've been burned by gaming chairs before.
The mistake most buyers make with the Opal? They trust the word 'ergonomic' on the box. I did too, for about a week.
Here's what I actually found after assembling it, adjusting every lever, and sitting on it for full workdays.
The seat pan is shallow for tall frames
This is the one thing I measured before buying, but I should have measured myself first. The Opal's seat depth is about 19 inches from front to back. If you're 5'11" or taller, your knees will likely hang past the seat edge — meaning you can't support the back of your thighs without your calves touching the seat front.
I'm 6'1", and when the backrest is upright, I have about an inch of thigh unsupported. Not a crisis, but after hour five, it's pressure under the knees.
The seat depth adjustment? There isn't one. The sliding mechanism on the base only moves the whole seat forward and back, not the pan relative to the backrest. So you have to choose: sacrum support or full thigh support. I ended up putting a small pillow behind my lower back to keep my butt from sliding forward, but that changes how the lumbar hits.
If you're under 5'9", this likely won't bother you. But for taller people, that missing seat slider is the real budget compromise.
Armrests that move but don't lock everywhere
The 4D armrests are a definite upgrade over most chairs at this price. You can slide them in/out, up/down, angle them slightly, and rotate them inward. But they don't lock in the rotated position — they're held by a snap detent. After about three months, mine started sliding back to center when I leaned on them.
Also, the armrest pads are rock hard. If you rest your elbows while typing, you'll feel it. I've been using a foam pad on top — ugly but functional.
The height adjustment range is decent: 8.5 to 12 inches from seat base. That's enough for most desk heights, but again, check your own numbers.
Lumbar support that's just a curve
The 'lumbar support' is really just a fixed curve in the backrest, controlled by a knob that tightens the cushion into your back. Good in theory, but the range is tiny. For me, at 180 lbs, the knob went from 'nothing there' to 'poking too hard' in about two turns. There's no way to make it support the mid-back independently.
On the other hand, the backrest does recline quite far — about 138 degrees. The lock applies at any angle, which is better than many chairs that only have three preset recline positions. During breaks, I lean back to 125 degrees and read. But the seat base doesn't tilt with the backrest, so when you recline, your pelvis slides forward. Again, that pillow helps.
Build quality: surprisingly solid for the price
Assembly took me about 35 minutes with a second person to flip the chair over. The gas lift feels sturdy, no wobble in the base, and the material (PU leather) still looks fine after four months. That's more than I can say for a $200 chair that started flaking around the armrests after month two.
But the stitching on the seat front — where your thighs press — is already showing wear patterns. Not broken, but visible. And the PU leather doesn't breathe as well as fabric. On summer afternoons, my back gets sweaty against the backrest. You can't just crank the AC either, because the foam is dense and holds heat.
For contrast, I'm testing a Furmax Office Chair: 90 Days at a Desk, No Hype right now, and the fabric mesh seat is notably cooler. But the Furmax has nowhere near the recline range or armrest adjustability.
What the specs page doesn't tell you
The pivot point of the recline is NOT at your hip joint. It's further back, so when you lean back, your knees lift off the ground slightly. That's normal for many chairs, but it matters if you like to keep feet flat. I have to angle my feet out to compensate.
Also: the chair's armrests sit slightly narrow relative to the seat base when rotated inward — I can't get my elbows to rest without my shoulders hunching if I type for long stretches. That's a shoulder-knot generator.
If you're looking at the Opal mainly because of the high back — it does come up to about shoulder height on me, but the headrest only helps when reclined, not when sitting upright at a desk. For upright desk work, I ended up removing the headrest for the first two weeks until I started reclining during phone calls.
After four months: what I'd tell a friend
Is the Opal a good chair? Yes, for the price. It's sturdy, adjusts more than most budget chairs, and the build quality holds up. But it's not an 'ergonomic' chair in the physical therapy sense. It's a cushioned bucket seat with a working backrest. If you have a history of back pain, especially in the lumbar region, this won't fix it.
I'm 6'1", 180 lbs, and my initial doubts about the seat depth were the right ones. The lack of a true seat slider is the main drawback. If you're under 5'10" with a shorter torso, you'll probably love it.
Before buying, measure your desk-to-floor height, your knee-to-floor length, and your forearm-to-elbow distance. Seriously. A Serta Big And Tall Executive Office Chair — Measure This Before You taught me that lesson. And if you're considering a chair without armrests, read my first-week notes on the Armless Task Chair: The First Week Makes or Breaks It.
The Opal is the best gaming-chair-shaped option under $400 I've tested. But 'best in class' doesn't mean 'right for your back.' I've postponed buying a second one for my wife until she sits in mine for a full afternoon.
That's the test that matters.
