If you’re reading about the Advanced SimRacing Advanced Formula Seat, you’re probably chasing one thing: a more reclined, locked-in posture that matches formula cars, prototypes and modern hypercars.
This guide compares the idea behind that seat style with the SIMGASM Atlas Formula seat, plus a quick alternative for drivers who want comfort first (Core Recline).
Why “formula posture” feels different
Compared to a GT posture, a formula/hypercar posture typically means:
- more recline in the torso,
- knees higher relative to hips,
- a more open hip angle that can reduce leg fatigue on long sessions,
- but also more sensitivity to seat fit (because you’re “locked in”).
Advanced SimRacing Advanced Formula Seat: published fit cues
ASR lists an angled seating position and provides useful “fit geometry” specs (seat widths and rail spacing). For example, they publish a rail spacing of 14.25" between mounting holes, which is a helpful number when you’re checking slider/bracket compatibility.
SIMGASM Atlas Formula: what it’s designed for
Atlas Formula is designed specifically for that more reclined posture, with a focus on comfort and stability:
- Memory foam style cushions designed to stay supportive for long sessions.
- Washable cushions (practical if you race a lot).
- Style options: different cushion colors and shell variants (including carbon options).
- Fit refinement: optional lumbar support options for drivers who need a little more lower back support.
Seat choice isn’t just comfort, it’s consistency
Small discomfort becomes big inconsistency. Here are two common seat mistakes we see:
- Seat too wide: you slide under braking and start bracing with your arms.
- Seat too tight: your shoulders fatigue and you lose steering smoothness.
Mounting and adjustability: what to plan
Regardless of brand, build seat adjustability into the rig:
- Side mounts / brackets: give you tilt control and help hit a true formula posture.
- Sliders: let you share the rig or fine-tune knee angle without changing pedal position.
For SIMGASM builds, the easy path is seat bracket set + dual locking sliders and then adjust in this order: seat height → seat recline → pedal distance → wheel distance.
Not sure you want a bucket? Try a recliner seat first
A bucket seat is amazing for performance, but it’s not for everyone. If you want comfort and a “daily chair” feel while still being sporty, Core Recline is the obvious alternative.
