Racetech race seats are regarded by many in the driving seat as the best in the world. Our composite and carbon fibre race seats are fitted to thousands of race cars, touring cars, rally cars, drift, drag and speedway cars. We keep people racing fast, safe – and we do it in ways that break the mould for safety, comfort and performance.

 From our HQ in Wellington, New Zealand, we design, test, manufacture and sell our comprehensive range of race seats, alongside other top-class race products, to iconic racing marques around the world.

Racetech seats and products perform. They’re comfortable; they fit perfectly, they feel secure, they connect you with your car in ways that give you the confidence to safely push your boundaries. We get that need to do better. It drives us, too—that competitiveness.

We know only too well that thing that happens when you feel the seat wrap around you. Suddenly what you see ahead of you becomes your world. That adrenalin rush and focus is addictive, calling you back week after week, race after race. It drives you to shave fractions off last week’s lap time, to out-position a rival, to throw everything you have at being as good as you can be.

No other racing seat manufacturer is more concerned about drivers. Our culture and purpose revolve around getting you and every other driver home. That determination to make sure racers get to walk away safely from their time on the track and the road plays out in every aspect of our approach. No detail is too small when it comes to saving lives.

Our commitment carries through to our insistence on quality production. The only price we put on safety is a fair one: we don’t skimp or cut corners—the best costs what it costs.

Our willingness to recognise and address issues stems from that deep Kiwi pragmatism that lets us chase excellence at the expense of tradition. We’re a practical, grounded and free-thinking team with an eye for detail and a steely determination to consistently and carefully introduce the evolutions that, over time, help make racing safer.

We literally help set the standards for keeping drivers safe globally. We are currently a member of the FIA IWG, the Industry Working Group that global body The Federation Internationale De L’Automobile (FIA) consults with. Our team is regularly sought out by national motorsport organisations to assist with improving safety standards and understanding driver safety. Here in Australia, we work closely with many V8 Supercar teams and the TA2 Australia Muscle Car Series supporting them with driver safety.

All of that means that every time you slip into a Racetech race seat, everything we know is right there with you.

We focus on designing, developing and producing the best race seats in the world. In fact, Racetech seats are used by some of the world’s leading teams and constructors, including Porsche, Aston Martin, McLaren, Chevrolet, Ford, Dodge, and Australia’s own V8 Supercars and TA2 Series cars.

 Racetech seats are robust and supportive. They’re made that way, and they are that good because we’ve made it our business to know what makes drivers tick. We combine safety, comfort and performance in seats that drivers can depend on and that represent true value for money. They are your added advantage.

Our knowledge and experience make us the world leader in racing seat science. Our patented back mounting gives you solid contact with your vehicle and improves your feel of your race car. Not only does this enhance your performance, you’re also safer racing this way. Tests have shown that if you support and maintain alignment of the head, shoulders, pelvis and thighs, drivers can withstand enormous decelerations with minimal or no injuries.

Our expert team is passionate about the tiny details of your racing machine’s seats, harnesses, and other vital components. For us, performance is about much more than just reducing weight. All Racetech seats have parallel sides for ease of fitting and driver positioning. The lack of flex in the shoulder area of our seats helps reduce fatigue and improves safety. The six-point mounting method we pioneered helps improve car handling and the ability to tune the chassis. These features, and more, literally make the difference between life and death or injury.

With a Racetech seat, you don’t have to pay top dollar to take advantage of our innovative thinking and design. Many of the features in our top-of-the-range seats carry right across our range. No matter which seat you invest in, you still get back-mounting, square shoulders and the simple, nothing-to-fail cooling system that Porsche Works and V8 Supercar drivers swear by.

And when it comes to sizing, no other racing seat manufacturer is more accommodating. We offer you the widest range, and each seat in all our ranges includes an ergonomically moulded removable base cushion and seat geometry that ensures you’re always sitting comfortably.

Choose a Racetech seat. They’re made for people like you. Drivers.

All-around thumbs up!
Size: 934W-Z, Color: Black
So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

Perfect Balance of Comfort, Support, and Style!
Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive. The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height. The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks. Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space. If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality. Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy. Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.

Good Value for a Tall Chair
Size: 934W-Z, Color: White
I have received this chair just today and would like to give my first impressions of it. Height is super adjustable as well as the foot rest. My desk is very tall (~34 inches vs standard ~29 inches) and does not suit a standard height chair. This chair's height is enough to sit comfortably at mybut also still having adjustment to be even higher. Lumbar support is a manual adjustment that can be adjusted by sliding the lumbar piece up or down and it seems it can be tiled as well. No reclining feature or slight backrest tilt adjustment. I'm used to my chairs reclining so it feels a little awkward siting in a flat base and straight backrest. I feel like I'm sitting too forward or leaning forward slightly but is probably something I can get use to. Easy to put together and feels very sturdy. Plastic parts of chair are made from a really sturdy plastic, like playhouse plastic materials. Wheels roll around carpet easily. Mesh seems to be a strong material, though the mesh feels kind itchy on bare skin. Overall, I think this is a good chair to get if you're needing a tall chair for a good value and can sacrifice no backrest tilt.

Unexpectedly great chair - easily adjusting it to suit changing day-to-day needs makes it incredible
Color: Black Rhythm
The bottom line on this chair is that it is unexpectedly miraculous. After just 3 days, I've found it is unconventionally comfortable and the thing that makes it unique is that it renders adjusting it a normal part of its usage. I was originally like most folks, I presume - set the chair and then see how it does - but this chair demands that you use its intuitive controls to change things around as your needs change during the day. It is so easy to do, and that is where the magic is. I graduated from an excellent budget chair, the Alera Elusion high-back that is very adjustable. After over 5 years of pretty heavy usage, though, it was showing its wear, and I was really starting to feel the cushion every time I sat on it. I also started to experience some neck, shoulder, and lower back discomfort, and decided it was time to graduate to a better solution. I did not consider the Embody chair initially. At first glance, it looked a bit weird, and it was also on the expensive side, so I blew right past it. My initial starting point was the Aeron. I had used one at work years ago, and I recalled its adjustability. My body was much younger when I had used it, so I didn't experience its ergonomic benefits as well as I should have. I also looked at Steelcase models as they had some good reviews. Steelcase didn't fit my requirements as well as the Herman Miller solutions, so I gravitated strongly to the Aeron and was about to push the trigger on the order. A last second search on YouTube led me to the Embody and I was intrigued because of a couple of factors: the intuitiveness of the controls and the emphasis on the flexibility of the back and seat. The people that loved it REALLY loved it, and that, compounded with the Herman Miller return policy interested me enough to try it. So, here are some findings from the past 3 days: First, the seat is incredibly comfortable. The pixellated solution flexes with the weight that is applied to it, and it makes you feel as though you are suspended with no uncomfortable pressure points - this completely resolved the issue I was facing with the old Alera. It breathes well, is cool, and just invites you to sit down. The seat length adjustment required a little strength, but works well - you are not stuck with just the default length that might be either too small or too large. I had to adjust a couple of times to get just the right length. Once set, I don't foresee having to adjust it often. Second, I have found that I change the recline setting on the chair frequently. When I am typing, I set it so that it is relatively rigid, and when I am mostly reading, I set it so that it flexes more. There are several aspects to this - for typing, I set the tilt limiter to the position that allows the least possible movement or the next step down. I tighten the recline knob to keep me more upright, and adjust the back to a comfortable setting. It is all really easy, and the chair gives immediate feedback to ensure a good setting. When I am reading, I set the recline to setting 2 or 3 (more recline) and relax the recline a bit. That gives me the opportunity to lean back as needed and move around, with full support. If I am watching YouTube, I go to the most relaxed recline setting, and adjust the back to a less aggressive setting, and it is very comfortable. Setting/resetting all of the controls is responsive, easy, and intuitive. I never thought that this would be so required in a good seating experience. Third, I fiddled with the height of the chair to find the most comfortable setting. I use an iMovR standing desk and a Kinesis Advantage keyboard. I initially set the chair/desk combination so that my feet were flat on the ground and so that my forearms were angled downward slightly - supposedly more ergonomic. I ended up with some discomfort in my right wrist. Through experimentation, I found that raising my table or lowering the chair so that my forearms are angled a bit upwards got me in the correct wrist position for the keyboard, since it has wells. I am more upright with these settings, and am finding that my back is much more in contact with the chair, providing great and flexible support. This may not work well for folks using normal keyboards, but it is great with the Advantage. I also adjusted the height of the monitor so that it is a little higher than most ergonomic folks would recommend. I had found that by keeping the top of the monitor strictly at eye level as recommended, I was moving my head down to read the lower part of the screen, and this was causing some neck discomfort. My current setting is very comfortable. I have spent long hours in this chair over the past few days, and I am very impressed. My experience with the Alera and Aeron, both excellent chairs, is that they unwittingly promote the initial set and don't adjust paradigm, simply because adjustments, though technically possible, are not as integrated into the seating experience - you have to bend, get up, or twist unnaturally to do the adjustment. The Embody chair, on the other hand, encourages adjustments while you are in the seated position because the controls are few and easy to reach. This allows adjustments that correlate to the changing needs of our bodies throughout the day with immediate feedback because all of the controls are so well placed and simple to use. Flexibility and consistent support are inherently part of the design. No doubt that this chair is expensive, but with the generous 12 year warranty, this chair is about as good an investment you can make for your back and your general health if you spend significant time in a chair.
