The SIMGASM Atlas seat is a strong choice in 2026 if you want a rigid fixed back seat that switches between a GT and a Formula position on one base. Its biggest pros are the patented modular design, washable memory foam cushions and a built in bass shaker mounting pattern. The main cons are that seat brackets are sold separately, the back does not recline and the second upper section is an extra purchase.
Below we go through every pro and con in plain words, so you can decide if the Atlas fits your driving style, your rig and your plans.
What is the SIMGASM Atlas seat?
Before the pros and cons, here is a quick look at how the seat is built.
A modular seat with a shared base
The Atlas GT and Formula seats share one lower base. On top of that base sits either a GT upper section for an upright position or a Formula upper section for a low, reclined position. Each upper section has its own cushion set. You buy a complete seat in one configuration and add the other upper section later if you want.
The shell comes in black, white and a forged carbon look. The Formula version uses a carbon composite shell. All versions mount from the side with a seat bracket set.

Who designed it
The Atlas comes from SIMGASM founder Johan Akkerman. Before SIMGASM, he worked at Trak Racer, where he was responsible for the design of the TRX seat. He started SIMGASM with product development in January 2026, and the company was formally incorporated in February 2026. The Atlas is the result of that seat experience combined with years of racing at world level in esports.
What are the pros of the Atlas seat?
These are the points where the Atlas stands out in 2026.
Two racing positions on one platform
This is the headline feature. With the patented Atlas design you change from GT to Formula by swapping the upper section, not the whole seat. That saves money, space and a second set of brackets. Read exactly how you switch an Atlas seat from GT to Formula.
A rigid shell for direct drive and load cell pedals
A fixed back shell does not flex when you push 100 kg or more into a load cell brake pedal. That keeps your position the same in every corner, so your muscle memory builds faster. With strong direct drive wheelbases, that stability shows directly in more consistent steering.

Cushions you wash, swap and personalise
The memory foam cushions come off for cleaning. Extra Atlas GT cushion sets are available in red, white, blue and orange, so you match the seat to a coloured cockpit. A dedicated lumbar cushion adds lower back support. Find out if you need a lumbar cushion in an Atlas seat.

Ready for tactile feedback
The shell has a predefined bass shaker mounting pattern and an extra point for accessories such as a cup holder or headset holder. So you add tactile feedback without drilling your seat.
What are the cons of the Atlas seat?
No seat is perfect, so here are the points to think about before you buy.
Brackets and extras cost extra
The complete seat does not include brackets. You need the SIMGASM seat bracket set to mount it. The second upper section, extra cushion colours, the lumbar cushion and bass shaker hardware are also sold separately. Plan your budget for the full setup, not only for the seat.
The back does not recline
A fixed back gives the best feedback, but you cannot tilt the backrest with a lever. You set the angle with the brackets. If you share your rig with others or also use it to relax, a recline seat might suit you better. Compare both types in our article on when to upgrade from a Core to an Atlas seat.

A seat for a dedicated rig
The Atlas is made for a cockpit, not for your desk. It needs a frame with side mounting points. If you still race on a desk clamp, start with a cockpit first. A seat slider makes forward and backward adjustment easy when several drivers use one rig.
Who should buy the Atlas in 2026?
The Atlas fits best when stability and flexibility both matter to you.
Choose the Atlas if you race GT and open wheel cars, use a direct drive wheelbase or load cell pedals, or want a seat that grows with your setup. Look at the Core range if you want a lower entry point or a reclining backrest. Not sure which type of seat suits you?

Questions about the SIMGASM Atlas seat
Here are quick answers to the questions buyers ask most.
Is the Atlas GT or the Atlas Formula better for beginners?
Most beginners feel at home in the Atlas GT, because the upright position works for most car classes. You add the Formula upper section later if you get into open wheel racing.
Are seat brackets included?
No. The Atlas uses side mounting, and the SIMGASM seat bracket set is sold separately.
Is the carbon version stiffer?
All Atlas shells are built to stay rigid under heavy braking. SIMGASM describes the carbon construction as a step further in stiffness with less weight, which suits premium builds where every detail counts.
Can I add a bass shaker later?
Yes. The shell has a predefined bass shaker mounting pattern, so you add one whenever you want.
