The Sim-Lab S1 Enduro GT bucket seat is built around a true GT driving position — a natural, upright posture that keeps you in control at the start of a stint and still comfortable at the end of one. It is Sim-Lab's endurance-focused sim racing seat, developed as part of their latest design generation, and it is rigid enough to belong on a high-end direct drive rig or a motion simulator.
A GT racing position you can sit in for hours
Most sim racing seats force a compromise: either a laid-back formula position that wrecks your back on long runs, or a soft gaming chair that lets you move around under braking. The S1 Enduro splits the difference the way a real GT car does. High-density cold foam padding distributes pressure instead of collapsing under it, integrated lumbar support holds your lower back where it should be, and split leg cushions let you work the pedals without the seat fighting your legs.
Breathable 3D mesh and removable cushions
The seating surface uses a breathable 3D mesh fabric that moves air instead of trapping it, which is the difference between a comfortable two-hour endurance stint and a sweaty one. All cushions attach with hook-and-loop fasteners, so they come out for cleaning or replacement without tools.
Rigid fiberglass composite shell
The S1 Enduro uses a glossy black fiberglass composite shell in a two-piece construction with a minimum of flex. That rigidity is what makes it suitable for high-torque direct drive wheelbases and motion platforms, where a flexing seat gives you vague, mushy feedback and squeaks under load.
Fits your cockpit and your harness
The S1 Enduro side-mounts on the industry-standard 290 mm bracket pattern, so it drops into Sim-Lab GT1, GT1 EVO, GT1 Pro and P1X cockpits as well as most third-party aluminum profile rigs. Bucket seat brackets are included. Pre-cut harness openings accept a 4-point harness, and the seat is compatible with optional seat sliders if more than one driver shares the rig.

Who this seat is for
Choose the S1 Enduro if you run long stints in iRacing, Le Mans Ultimate, Assetto Corsa Competizione or rFactor 2, if you are upgrading from a foam-padded gaming seat to a proper bucket, or if you are building a rig that needs to feel solid under a 12 Nm-plus direct drive base. Pair it with a Sparco seat slider if multiple drivers share the cockpit.
