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:

1. Seat too wide: you slide under braking and start bracing with your arms.
2. 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.

Recommended SIMGASM gear

• Core Recline seat for comfort and easy daily usability
• Atlas Formula seat for a laid-back formula/hypercar posture
• Atlas GT seat for upright GT driving styles
• Seat bracket set and dual locking sliders to dial in fit
