Artisans of Speed C1-XL Cold Fusion Sim Racing Seat

Built to order — current lead time 5–7 weeks. Each Cold Fusion seat is made in Europe after you order. This is not a stock item.

If a standard bucket seat pinches at the hips, you notice it every single lap. The Artisans of Speed C1-XL Cold Fusion is the wide-body version of the C1 — 30 mm more room across the hips and base — with the same four cooling fans built into the shell.

Room to actually sit in

The XL shell adds 30 mm at the hips (415 mm vs 385 mm) and 30 mm at the base, plus a taller backrest. If you have ever climbed out of a race seat with sore hips after a long stint, this is the one to buy. Everything else — shell material, cooling system, upholstery, harness slots — is identical to the C1.

Active cooling you can dial in

Three fans sit behind the backrest and one under the seat base, pulling hot air away from your back and legs. They are floating-mounted — load the seat up under heavy braking and they retreat into the shell, so you feel padding, never hardware. A 3D mesh layer under the main cushion spreads the airflow instead of leaving one cold spot, and a rotary dial built into the seat changes fan speed mid-session without you leaving the rig.

A real racing shell, not a gaming chair

The C1-XL is a single-piece glass fibre reinforced polyester moulding. One rigid shell means no flex and no creak when a high-torque direct drive base loads the rig up. It is finished in black velvet with four harness slots for 4, 5 and 6-point belts, and removable leg supports so you can fine-tune your seating position.

Key features

• Wide-body shell — 415 mm hip width and 530 mm base width for a genuinely roomier fit.
• 4 built-in cooling fans — 3 in the backrest, 1 in the base. Stay dry through long stints and warm rooms.
• Floating fan mounts — the fans move back under load, so you never feel them through the padding.
• 3D airflow mesh under the cushion spreads air evenly instead of creating one cold spot.
• Rotary fan-speed dial built into the seat — adjust cooling without stopping.
• Monolithic GRP shell — rigid enough for high-torque direct drive setups.
• 4 harness slots for 4, 5 and 6-point harnesses.
• Black velvet upholstery with removable leg supports.
• Side-mount fixing points — bolts to standard seat brackets and sliders.

Dimensions

The full dimension drawing with every measurement point (A–I) is in the image gallery. Product photography shows the standard C1 shell — the C1-XL is the same design in a wider moulding.

C1, C1-XL or C2?

• C1 — the standard touring car shape. The right fit for most drivers.
• C1-XL — the same seat, 30 mm wider at the hips and base. Choose this one if the C1 feels tight.
• C2 — the 'EVO' shell with wrap-around head and shoulder wings for a more enclosed, GT-style position.

Fitting it to your rig

The C1-XL uses side-mount fixing points and bolts to standard seat brackets. Add brackets — or brackets plus a slider for fore/aft adjustment — using the Mounting option above and they ship with the seat. Already running side mounts on a Sim-Lab, Trak Racer, Sabelt or other profile rig? The seat bolts straight to your existing brackets.

Before you order

• Built to order — current lead time is 5–7 weeks. Every Cold Fusion seat is made in Europe after you order, so this is not a next-day item. We confirm your build slot by email as soon as the order is placed.
• Sim use only. The Cold Fusion is not FIA homologated and must not be used in a road car or on track.
• Want your own design? The back and bottom cushions are fully customisable. Contact us for templates and pricing — custom builds take 4–8 weeks from final design approval.
