I call it the Motion Integrated G-Seat as it combines the strengths of a motion platform with those of a G-Seat and integrates them into one single system. It is able to deliver an unprecedented sensation of intense, swiftly reversible and sustainable feeling of motion and acceleration in all axes.
The prototype on the left looks (a bit) like an aircraft ejection seat, but the Motion Integrated G-Seat can be used in all kinds of seat-based simulations! Almost any effects resulting from acceleration can be simulated! From high frequency disturbances when jolting over road bumps or through aerial turbulence, to longer lasting forces when cornering a race car or ‘pulling Gs’ in a fighter jet. When you hit the brakes you get tossed forward into the harness, when you "pull G's" you feel pressed down into the seat. Flying upside-down lifts you upwards, feeling like hanging in the shoulder harness.
The effects induced by the Motion Integrated G-Seat are instantaneous, can reverse direction
swiftly and most importantly, are
- meaning they can last as briefly or as long as the simulated acceleration does.
The Motion Integrated G-Seat not only works great in VR, it immensely enhances the immersion, as the induced movement of the body correlates exactly to the natural shifting of the eyepoint during accelerated maneuvers (e.g. forward while braking, left when turning right, up during negative Gs and so forth).
Unlike other motion systems, the Motion Integrated G-Seat needs just a little more space than a static seat and can thus be incorporated into any fixed-base cockpit or car simulator. I have it installed in my F-18 flight simulator, which only provides a width of 53 cm (20,8 in) for the seat.
The Motion Integrated G-Seat uses pressure applied to crucial parts of the body by moveable elements in the seat pan and backrest, combined with tightening and releasing of the shoulder harness and seat belts, integrating everything into an overall motion of the seat. It can tilt forward and aft, left and right as well as move up and down by about 8 cm (3 in). This combination of motion and change in pressure is effectively creating the impression of beeing accelerated.
All effects of the Motion Integrated G-Seat are achieved by only three motors driving an internal mechanism of a sophisticated but robust array of force distributing rods and pulleys, resulting in low material costs, low weight and high reliability. The components used in the prototype cost me less than 1.500 €!
As I don't possess the resources to produce the seat in any larger quantity by myself at the moment, it is not for sale yet . I am currently looking for companies able and willing to produce and launch the Motion Integrated G-Seat. If you happen to be in charge of a suitable company, you are very welcome to contact me.

I would love to have something like this. I think kickStarter would be the way to go. However I would not be looking for a manufacturer that could produce this unit.
Prototyping, tooling and other associated costs would drive initial production costs through the roof. It's also a niche market so you wouldn't want to be looking at initial runs of 100-500 units to make it worth the manufacturer's time.
As a KickStarter project you and a team, if required prototype the unit, which it looks like you have already done.
You then break the unit into assemblies then start looking for suppliers of the parts and assemblies. Try to use off the shelf parts where possible.
Find a manufacturer or manufacturers for customized components as needed. You basically become a contractor. You choose what to fabricate or manufacture yourself.
A successful KickStarter campaign will provide funds to support this part of the project.
You set up a small assembly shop for final testing of the unit.
Again contract a packaging and shipping company for product delivery.
This lessens the stress of trying to do it all, it also gives you more initial control and costs over the project.
Just my thoughts (as someone who has been through this), hope they are helpful or give you some more ideas.
Hello Gcompc and thanks for all your thoughts and suggestions, they are highly appreciated!
Launching a kickstarter is a very realistic option I am looking into at the moment. But because I have offers from possible investors as well, I have to gauge which path would be better for this project.
I fully agree with the strategy you laid out but unfortunately, things are not that easy in the country I live because I cannot just build and sell technical stuff on my own without the proper qualification as an engineer or technician, which - as a pilot - I haven't. It is all very strictly regulated.
That is why I approached a qualified production company. They are just figuring out the production costs involved. I hope to be able to provide tangible updates soon! Thanks for your interest and please stay tuned!

I'm quite thrilled by your product. My interest is in belicopter flight simulation. I watched the videos several times but I wasn't sure if I was able to detect surge, heave and sway, important forces for helicopter simulation, particularly in the hover. Does your seat provide 6 DOF or fewer? Kind regards.
Thanks for your questions K Warner. The Motion Integrated G-Seat cannot be compared to a motion platforms in terms of degrees of freedom. It uses 3 DoF as the motion part, but in combination with the pressure part (base, backrest and harness), is able to simulate forces in all spatial dimensions! Other than a pure motion platform, these effects are sustainable and quickly reversible in direction. It can also simulate negative (upward) acceleration, which a platform cannot.

So, a new teaser on YT. Any news on your product?
Hey Terje, well there are bad and good news. So here's a little update on the project:
Unfortunately the mentioned company is not making progress in a reasonable timeframe.
So me and my business partner are now evaluating means of launching the seat ourselves! We already found a promising company for production and assembly in close proximity to where I live and are now searching for and reaching out to possible investors to get this going.
If you or anybody else want to help, please spread the word (e.g. in sim forums and communities) to reach a larger audience.
Thanks and stay tuned!

I'm wondering if this seat translates things like engine rumble, which is something passive and ever-present, like a JetSeat does? Or do I have to combine these to get it additionally?
My prototype has a bass-shaker included which adds vibrations from engines, tires and such. It is a simple but great item for those higher frequency vibrations. I think a commercial version should include one too, or at least provide addon possibilities.

Bergison thankfully invited me over to try his pit. Knowing his amazing work from this page, it did not prepare me for what it really does to you.
When you roll down the runway and hit the centerline lights with your nosewheel you get repetitive kicks, just like in the real plane. Flying low level, turbulence shakes you around in all directions.
I found myself subconsciously holding my breath before pulling into a g-turn and considering if I could take the load before pulling into another one.
Amazing what it does to your brain!
Thanks Scorpio, glad you enjoyed it!

Hi Volans, sorry to say there are no news recently from the company building the prototype. Their last word was they want to have it finished within 60 days, that would be around May/June...
Looking forward to it :)

Hi Bergison! I can‘t wait to (hopefully) get one or two of your seats for my future simulator.. are there already some news if you can continue working on a commercial production? Best greetings from Austria and thanks for inventing such amazing things! Alex
Hi Alex and thanks for your post!
Progress is slow but steady. The company I mentioned is now starting to build the production prototype. Too early to estimate a release date, but it seems to me more and more likely that this is going to happen after all!
Please stay tuned!
Julien posted on 08.12.2019 at 21:54
Hi Julien and thanks for your post!
1) no schedule for production yet I'm afraid. Me and my business partner are still negotiating terms with this mentioned company, but everything takes longer than expected although they say that they are eager to get this going quickly. A few days ago they sketched out about one month for prototyping works and another 6 months until a sellable unit could be available. Lets see...
2) Yes, a DIY option is part of the negotiations. We want to retain the rights to publish/sell DIY plans, instructions and a possible kit for the mechanics.
3) You are absolutely right about the movement and forces during accelerations. The seat does exactly what you described: e.g. in a left turn (car or aircraft), the seat tilts right (shifts body and eypoint) and increases pressure on the right side. This is perceived as being pushed to the right. During upward acceleration (flying inverted for example), the seat rises up (again shifting body and eyepoint), decreases pressure from base and back and tensiones the harness, giving you the impression of being lifted out of the seat.
I hope this answeres you questions, feel free to inquire again if not!
Pierre Lalancette posted on 24.11.2019 at 16:34
I've been building a 6 DOF for years now and your seat is making noise into our community. I think it is well done and I hope you get to the commercial units soon. I won't buy it, as I have mine, but I will try to steel every great ideas from yours and integrated them into my build. ;)
Long live to your G-Seat.
Alex posted on 05.11.2019 at 11:14
I have to say that I am totally blown away with the seat!
I have a few questions regarding it if you wouldn’t mind please answering.
1. I presume the batteries are used to supply the power for the seat motion.
a. I am curious why you have designed it to run on batteries vs running on mains power?
b. What is the battery endurance in hours?
c. How long is their charge time?
2. Do you have any plans for adding the stick and/or throttle mounting base to work in conjunction with the seat? As from I can see, the seat will do all the movement but the stick will not move with it.
I am totally interested in this and would absolutely love to buy one when available to the public!Awesome work!
Hi Alex, thanks for your nice comment! To your questions:
1) correct, I use two AGM batteries '12LCP-50' with 50 Ah each.
1a) the motors frequently hit their stall current due to the quick reversal of motion and thus produce quite large spikes in current, reaching over 30 A per motor. Although I guess there are PSUs available which can handle this, it is much easier (and cheaper) to use batteries. Another option would be to use (smaller) batteries in parellel with a PSU or charger, but this again would add to complexity and costs.
1b) I have not measured max. endurance yet. It would also heavily depend on the kind of usage. Frequent, rapid movement (e.g. aerobatics, dogfighting) of course draws more amps than an airliner. My batteries are not nearly half empty even after several hours of heavy 'F-18' duty.
1c) see 1b. Also depends on the used charger.
2) There might be this option on a future commercial version, but for my seat, no. I found the motion relative to fixed controls (in my cockpit as well as during tests with a steering wheel) perfectly appropriate for the respective acceleration. Try it yourself in a car: when you hit the brakes, you get pushed closer to the steering wheel. It would feel strange, if the wheel also moved forward, no?
It actually looks quite promising that the seat will get available in the near future. Me and my business partner are just starting negotiations with a company very eager to build and launch it :)
I hope to be able to provide more details soon, stay tuned!
Nicholas posted on 27.10.2019 at 2:58
Love the work you've done. Not gonna lie you kinda beat me to the punch. Ive been sitting on a simular yet different idea, one that just uses straps so congrats. Also i cant wait to buy one, but im curious how much one might cost, as well as if it'll fit in an rv? Also just an fyi i posted a question on your most recent youtube vid. Last question, can the base be shortened at all?
Hi Nicholas, thanks for your comment! Using straps (or flaps) alone does actually provide good feedback, but I found the combination of motion AND pressure to be really convincing. As I am not going to produce a commercial version myself, I cannot tell at the moment how much one unit is going to cost. It will heavily depend on production numbers, used materials and included features. As the internal mechanism and actuation is not very complicated though, I have hopes that it will be affordable to the public. The seat does not require a lot of space as you can see in the video where the seat is installed in my F-18 cockpit. The base of the seat could me smaller if needed, as it only houses the batteries and parts of the motors.
Just to be clear, if i wanted a seat reclined at a 35-40° angle with the seat itself(i.e. the part your glutes are on) being roughly 3 inchs from the floor to the bottom of the backside, it could be done?
That would mostly depend on which kind of actuators/motors you want to use and how much space they require. The force distributing mechanism of the seat itself does not take up a lot of space, but given that the amount of vertical travel is about that far, 3 inch from the floor would certainly be too little.
So i just found a g seat that uses simular principles, may i post the link?
Sure, please do.
So i was looking for your videos and i found this. https://youtu.be/aQMNXqJmPIE i dont think they use the strap idea you use though.
Right, this is the GS5 G-Seat. It is also a G-cueing system in the form of a seat and, like mine, has moveable internal elements to simulate pressure on the body. But this is where the similarities end. The GS5 is an otherwise completely static system, which means it does not move the body around in 3 DoF like the Motion Integrated G-Seat does. It can thereby not provide the immersive combination of motion AND pressure and also features no veritable eyepoint shifting with acceleration.
Moreover, it has no moveable seat belt and shoulder harness (as you correctly observed) and can thereby not truly simulate acceleration away (like forward or upward) from the seat, which is essential in cars (forward for braking) as well as in aircraft (upward for negative Gs).
I don’t want to disparage the GS5 seat here, it is certainly a capable system in its field. But you can’t meaningfully compare it with the Motion Integrated G-Seat.
Ok so lets take just the preasure and the straps but no motion parts, how low would the back of the basebe able to sit when tilt at a 40 degree angle?
Ian posted on 21.10.2019 at 20:22
Very interested in your seat! Can you give updates about your project? When this comes out, I\'m buying!!!
Hi Ian,thanks for your post! Many companies showed interest in the seat and two (one in the US and one in Europe) are currently evaluating a possible manufacture and market launch, but it is too early to say if and when. I hope to be able to give more definitive news soon! Stay tuned!
Jamie posted on 07.10.2019 at 4:12
do you have plans? I want to try and build one of these.Thanks!
Hi Jamie, plans are not available yet, as I am still in the process of trying to bring the seat to market. Thank you for your understanding.

The_Ignotus posted on 19.7.2019 at 22:16
Hi and thank you for being an enthusiast ;)Are there any updates on the talks with the potential manufactures?Did you think about making the Ejection levlers function as buttons?And did you think about adding a stick base mountig plate for Thrustmaster Warthog and Virpil for example, like a plate with predrilled holes?And most importand for me:Is this seat / XSim compatible with DCS World?
I defently want one of theese, because it is the FIRST seat i find in the two years im searching for a f-18c seat on which it makes sense to start building a VR Sim system around. :DThank you for your dedication and work!!!
Hi The_Ignotus and thanks for your message!
1) There are currently two companies (one in the US and one in Europe) evaluating a production. Both are interested in bringing the seat to market but it will take some time.
We are also in contact with some other companies and individuals for possible production and partnership. To sum it up, there is a lot of interest but at the same time it is hard to find a company wich has the expertise, facilities AND the financial background to build and launch a completely new system.
It all takes longer than I expected, but it looks promising that the seat will be available for the public "someday"...
2) Both the side levers and the ejection handle are operative on my prototype and I agree with you that prefabricated mounting options for flight controls would definitively be a good thing to have on a future consumer version.
3) Yes, my seat uses x-sim for simulator interface and I have currently set it up for both FSX/P3D and DCS. The exported parameters out of the sims are a bit different, but work equally well.
My guess is that a future marketing company would either use their proprietary software or make the hardware x-sim compatible (or maybe both?).

Hi! Looks dope. I you ever find a company to make it or agree to sell plans/instruction, hit me up, I would definitely be interrested.

Digger posted on 22.5.2019 at 5:56
This seat dose look really great, and the design looks robust, what about noise, latency , software,? I am interested should the seat go to manufacture. As I am a real world pilot I think it could be used in semi professional flight sims for training. Keep me posted please!
Thanks Digger, the seat has no perceptible latency and the sound it emits is easily drowned out by engine noise. During flight, I don't hear the motors and mechanics of the seat at all. For software interface I use X-Sim at the moment.

I want this for Elite: Dangerous. Kickstarter this. I will fund you. :)
Nick posted on 28.4.2019 at 20:53
So, first you need to file for a patent. Once that's done, talking to contract manufacturers would be next step. You will want to focus on manufacturers that are lower volume, and preferably ones that have facilities in Mexico or Asia.
I would recommend crowd funding this if you are serious, but plan for manufacturing to be more expensive than you think. Most tech Kickstarters fail at this step, as reliability testing and design changes as a result run up the costs quickly.
Good luck! I've bookmarked your site to keep tabs on it once in awhile. I'm quite interested in purchasing this if it becomes available!
Thanks Nick, all steps you mentioned (except the kickstarter) have already been taken care of. I received a positive review for an international patent application (PCT) and we are in talks with potential manufacturing companies. I'll keep you updated!
Jett posted on 21.4.2019 at 21:30
Your seat looks to copy the existing design of the Simxperience G-Seat.
No Jett, not a bit! The mechanics of my seat are fundamentally different. They drive seat motion, seat geometry and harness belts all at once.
To my knowledge, the Simexperience seat is static with moving paddles and can as such be mounted on some kind of ancillary motion system.
Ha, ha, it's like comparing a Ford T-Model to a Porsche GT2. Ok both have four wheels, but that was it *g

Absolutely awesome Motion Integrated G-Seat man. Thanks.
I have a couple of Andre's KW-908 jet-seats, one in a Block 52 F16 cockpit and another in an F1 Car simulator (both home built) which have been great and added to the total immersion of both sims I use.....but this is a totally different dimension and as I can see immersion level. I am excited and thanks for sharing your awesome project.
I to would be extremely interested in a Motion Integrated DIY kit. Have you made any progress along those lines in the past couple of months?
thanks for your comment! I am still investigating means of making a commercial version of the seat available not only for professional use but also affordable to the sim community.
The DIY version with a kit and/or the plans and instructions is still also something I'd like to realize, but it will take some more time, hang on!
Peter posted on 28.2.2019 at 15:31
Unbelievable, this is amazing. I just got into VR and this would add so to the immersion factor. I do think you need to have a real cockpit with switches as you will not be able to move a mouse cursor to manipulate switches.
I hope you find a way to market this. I could imagine selling a part list and plans too but how do you prevent people from sharing it?
Keep me posted!
Thanks Peter! Having a "real" cockpit is nice of course, but you don't necessarily need one with the seat. It is also great with just some controllers and a screen or with a VR headset.
Actually, it is also hard if not impossible to manipulate switches in a real aircraft during agressive maneuvers or severe turbulence. The same applies for using a mouse cursor, it only adds to the realism!
Alex Antonio posted on 26.2.2019 at 15:20
Incredible work. How much maintenance is required on the seat? Are the parts easily replaceable/repairable if something breaks?
Thanks Alex! Apart from charging the batteries, there is no maintenance required.The internal mechanism is very robust, I doubt something is going to break there anytime soon. The weakest parts would be the motors, but the seat is designed not to demand their maximum capacity. They merely get warm even during long operation. If a part there should fail, it would easily be accessible for repair or replacement.

Wow! This is a really amazing concept!! Are you, or will you do a video of flying your F-18 with your Motion Integrated G-Seat? And Have you thought about doing a video such as MRPilot does in mixed reality. With your MIG-Seat (cool acronym, huh? :-) ) and F-18 cockpit, that would make a really awesome video!
(lot of work though)
Thanks for sharing!
BTW, the links in your earlier reply below are broken.
Thanks George! Like I said at the end of video #2, I am working on the next video right now, showing the seat inside my F-18 simulator. I don't think I can produce something as cool as MRPilot though, but I'll do my best to show the seat performing in an aircraft as descriptively as possible!
