OPSeat Grandmaster Review: The Best Racing Chair Under $300?

OPSeat Grandmaster Review: Pros & Cons


The flatter seat base on the Grandmaster allows for a more comfortable sitting experience


You can get the OPSeat Grandmaster in over 10 different color schemes


The Grandmaster is one of only a few sub-$300 gaming chairs that offers a flat seat base, 4D arm rests, and tilt & lock feature.


I found the Grandmaster more comfortable without the lumbar support pillow on

I’ve got another racing-style gaming chair review! Today, I’ll be reviewing the OPSeat Grandmaster. The Grandmaster is now the sixth gaming chair that I’ve reviewed in the past year. You can get the Grandmaster for $299 on both OPSeat’s website and on Amazon—but, if you go through our link to OPSeat’s website, you can get $10 off your purchase.

The chair isn’t perfect, but it’s pretty darn good. In fact, I’d say that of the six chairs that I’ve reviewed over the past year, in my opinion, only the Secretlab Titan offers a better sitting experience. But, the Titan costs ~$100 more.

So, I think at its current price, the OPSeat Grandmaster is a more affordable alternative to some of the more expensive gaming chairs out there. But, let’s dive into where the Grandmaster stands out and what its flaws are, minor as they be.

OPSeat Grandmaster: No Bucket Style Seats! Flatter Seat Base FTW

I’ve sat in enough of these racing-style chairs now to know that their biggest flaw, in my opinion, is their bucket style seats. I’m not alone either. Many out there think the deep bucket style seats that most gaming chairs come with are pointless. Bucket style seats are designed to hold racecar drivers in their seats when they’re zipping around tight turns. But, for PC gamers who are stationary while they game, the bucket style seats offer nothing to improve the sitting experience.

And, for me, I’ve found the bucket style seats to be a hindrance. I sit all day in my chair and I adjust my position on a regular basis. At times, I like to sit with my legs further apart. The bucket style seats make it difficult to adjust in my seat and to sit with my legs further apart.

OPSeat Grandmaster Flat Seat Base

So, the best part about the OPSeat Grandmaster for me? It’s the flatter seat base. I can sit wider in the chair. I can adjust without feeling squeezed into the seat. And, overall, its just more comfortable to sit in.

Some people do like the tighter fit of the bucket-style seats, though, and if that’s your cup of tea, there are a ton of options out there that do have bucket-style seats (OPSeat’s Master series chair has them and so does Secretlab’s Omega, or DXRacer’s F-Series, etc.)

But, if you’re like me, and you prefer a more “open” seat base, or you’re a larger gamer who absolustely needs a less restrictive seat base, then the OPSeat is a chair that will at least get that aspect right for you.

Adjustability On Par With More Expensive Gaming Chairs

One of the great things about gaming chairs is how many adjustment options they have. Pretty much any gaming chair offers at least, height adjustment (at the seat base), arm rest height adjustment, and the ability to recline backwards.

The OPSeat Grandmaster can do all of those and more.

OPSeat Grandmaster 4D Arm Rests

The Grandmaster comes with 4D (four directional) arm rests, which means they can be adjusted in four different directions (duh!) They can be adjusted up and down (standard), side-to-side, backwards and forwards, and at a 45-degree angle inwards, and a 45-degree angle outwards. 4D arm rests are pretty rare on a sub-$300 gaming chair.

Another nice feature on the OPSeat Grandmaster that isn’t common on all PC gaming chairs is its tilt and lock feature. A lot of racing-style chairs can tilt backwards at the seat base, but not all of them can lock in place at a tilted position. The Grandmaster can.

OPSeat Grandmaster Tilt and Lock

The tilt feature on the Grandmaster allows the seat base to tilt backwards up to 12-degrees and you can lock it into place at multiple angles in between.

The Grandmaster’s back rest can also recline up to 135-degrees.

OPSeat Grandmaster Recline

Ultimately, the tilt and lock feature and the 4D arm rests are features that are normally found on more expensive chairs $300-$400+. So, the fact that you can get both of those features on the Grandmaster for under $300 makes the chair one of the better value options currently on the market.

How Does the OPSeat Grandmaster Handle Lumbar Support?

Like most racing-style PC chairs out there, the OPSeat Grandmaster comes with a lumbar support pillow. Along with bucket-style seats, I’m not a huge fan of the lumbar support pillows. For me, I find them more uncomfortable sitting with them on than with them off.

Of course, lumbar support is important, and to go without any kind of lumbar support can have its own downsides. The main problem I have with the lumbar pillows, though, is that there is no way to dial them back. You either get the bulky lumbar pillow, or nothing at all.

OPSeat Grandmaster Lumbar Support Pillow

For me, most of the lumbar pillows are too big. And, the lumbar pillow that comes on the OPSeat Grandmaster is one of the bigger lumbar support pillows I’ve seen.

I’ve sat in the Grandmaster with both the lumbar pillow off and on and, for me, the chair is more comfortable without the lumbar pillow. Although, if you’ve got a bad back, or you prefer more lumbar support, the larger pillow might be what you’re looking for.

Dimensions, Comfort, & Color Options

The OPSeat Grandmaster isn’t the biggest chair out there in terms of its dimensions, but its far from being the smallest. And, again, because of its flatter seat base, the Grandmaster will actually feel more spacious to sit in than a lot of chairs with bucket style seats that have a wider listed seat base.

OPSeat Dimensions

The seat base on the Grandmaster is 21-inches wide and 20-inches deep. And, its back rest is 33-inches tall and 21-inches wide at the top and 23-inches wide at the bottom. The chair’s seat base height can be adjusted from as low as 18-inches off the ground to as high as 20-inches off the ground.

As a comparison, the more expensive Secretlab Titan comes with a seat base that is 22-inches wide and 21-inches deep. Its back rest is 34-inches tall and 23-inches wide. And, you can adjust its seat base from as low as 19.5-inches off the ground to as high as 23-inches off the ground.

The similar-priced DXRacer F-Series has a seat base that is 20-inches wide and 18-inches deep, with a back rest that is 33-inches tall and 23-inches wide. And, its seat base height can go as low as 18-inches off the ground to as high as 22-inches off the ground. It’s important to note, though, that while the DXRacer F-Series has a 20-inch wide seat base, that includes its bucket style seats. So, really, its seat has significantly less room on it than the OPSeat Grandmaster’s seat base.

The chair also has a weight capacity of 300-pounds. And, while that doesn’t make it the most heavy-duty option out there, it is sturdy enough to hold most people.

How Comfortable is the OPSeat Grandmaster to Sit in?

Obviously, how comfortable a chair is to sit in will be its main selling point. And, I’ve tried to lead into how comfortable the Grandmaster is by discussing its seat base, its adjustment features, and its lumbar support.

I’ve said it multiple times in this post, but the biggest thing for me regarding a chair’s comfort is how much room it offers me. I’m more comfortable in a chair that I can move around in than I am in a chair that hugs me tightly. And, in that regard, the Grandmaster’s wide seat base is a big plus for me.

And, because the Grandmaster also comes with a bunch of differenc adjustment options (as I’ve discussed above), it has been easy to put it in a position that offers the most comfort. The extra adjustment options are also nice because I don’t like to sit in the same position all day long. If I want to recline back slightly and watch a video, I can do so in this chair. If I want to sit upright to stay alert when I’m gaming, I can do that also. So, in terms of being able to adjust the chair into a position that offers maximum comfort, the Grandmaster nails that as well.

OPSeat Grandmaster Comfortability

The only area where I found the Grandmaster lacking in comfort was in its lumbar support pillow. But, as I’ve mentioned prior, I haven’t really liked any of the lumbar support pillows on the chairs that I’ve reviewed. Fortunately, I found the chair a lot more comfortable with the lumbar support pillow off.

Another unique feature on the OPSeat Grandmaster is the perforated PU leather on the mid-section of the seat base and the mid-section of the back rest. I haven’t seen this on any of the other PU leather chairs I’ve sat in and its a nice feature as it will increase the “breathability” of the chair, which, ultimately just means that it won’t get as hot. I can’t say for certain whether or not it has helped (it’s the end of Winter where I am—so, still pretty cool), but the Grandmaster definitely hasn’t gotten hot while sitting in it.

OPSeat Grandmaster Perforated Seat Base

Overall, the OPSeat Grandmaster is a very comfortable chair to sit in. Its flatter seat base and roomy dimensions make it a viable option for any kind of user, whether you have a smaller frame or a bigger frame.

OPSeat Grandmaster Color Options

One other plus with the Grandmaster is how many different color options it comes in. The chair comes in the 11-different color schemes shown below:

OPSeat also throws in two different color options for the accents on the wheel base, too. You can either go with all-black, or the accented color you chose.

Final Verdict: The OPSeat Grandmaster is Probably the Best Racing-Style PC Chair Under $300 and one of the Best Value Gaming Chairs Overall

The OPSeat Grandmaster has just about everything you could want from a gaming chair. Its flatter seat base offers a roomier sitting experience, it has a ton of adjustment options (including 4D arm rests and the tilt & lock feature), it comes in a bunch of color schemes, and it has an affordable price tag.

The only thing I didn’t really like about the Grandmaster was the lumbar support pillow. But, I don’t like lumbar support pillows in general and, considering that almost every other racing-style chair’s lumbar support feature is a lumbar pillow, you won’t be able to find a gaming chair in this price range with a better lumbar support option anyways.

I think the main selling point of the OPSeat Grandmaster, though, is that it has a lot of the features that higher-end models have, but at a lower cost. So, if you don’t want to pay over $300 for a gaming chair, the OPSeat is probably your best option.

Verdict: The OPSeat Grandmaster is easily one of the best gaming chairs under $300. It ditches the restrictive and uncomfortable bucket-style seats for a flatter (and more comfortable) seat base, it has a ton of adjustment options (including 4D arm rests), and it comes in at a reasonable price.
