Cobra Monaco 40th Edition Bucket Seats with Custom Tartan Trim
Every so often, something genuinely special passes through our showroom, and this pair of Cobra Monaco 40th Edition bucket seats was exactly that. Made specifically for one of our customers, these seats were finished with a completely bespoke tartan fabric in a striking red, green, blue, and black colour scheme. The tartan wasn’t chosen from a standard Cobra catalogue either; it was personally sourced and supplied by the customer, making this a one-of-one design tailored to their taste.
Seeing these seats in person was a real highlight for the team. We carried out our usual pre-delivery quality checks before they were dispatched, and the end result was nothing short of stunning. The vibrant tartan pattern sat beautifully alongside the seat’s vinyl outer trim and classic eyelet detailing, giving the whole seat a retro motorsport look that felt both unique and timeless. It was a reminder of just how far you can take a seat design when working with the right brand and a clear vision.
Our customer took the already brilliant Cobra Monaco 40th Edition and gave it even more character. The seat’s retro lines and classic shape were a perfect match for the fabric, and the result wouldn’t look out of place in a period rally car, a heritage road build, or even a classic showpiece project. It’s not every day we see this level of customisation, and it was a pleasure to have it in our hands before it headed out the door.
Cobra’s Seat Customisation Options - Our Customers Choice
Cobra’s Signature range allows for complete customisation of their entire bucket seat line-up. Whether you’re working with a steel frame seat like the Monaco or a fibreglass competition seat from their FIA-approved range, you can configure it to match your build.
Their Signature programme offers a wide choice of trim materials, colours, stitching, panel layouts, and even split-trim designs. Customers can mix and match vinyls, suedes, leather, and tartan. And in cases like this, you can go a step further and supply your own fabric, just as our customer did for this stunning tartan finish. This gives you complete control over the look and feel of the seat, making it a perfect match for retro builds, show cars, or personal restorations.
All Cobra Signature seats are made to order in the UK. These options aren’t held in stock, so lead times apply, but the result is worth the wait. In our showroom, we keep a range of standard Cobra seats in black trims for you to try out, but for one-off designs like this, we’ll always help guide you through the Signature process online.
Cobra Monaco 40th Edition in Tartan Trim
The Cobra Monaco Pro 40th Edition is a special version of the popular Monaco bucket seat. It features the same steel frame construction and FIA homologation but with classic styling details that set it apart. This includes vintage-style eyelets, vinyl outer trim, and a choice of tartan fabrics on the centre panels.
Our online listing includes pre-set tartan trim options, allowing you to choose from popular heritage patterns. However, as seen in this recent build, you can also supply your own tartan fabric and work with Cobra to create a completely personalised finish. The mix of old-school styling and FIA motorsport approval makes this seat ideal for both classic road builds and retro-inspired competition cars.
Its firm support, deep bolsters, and supportive structure make it ideal for use in rally, track day, and fast-road vehicles with a nostalgic edge.

- Steel frame bucket seat with classic styling
- Full FIA 8855-1999 approval
- Signature eyelet design and vintage detailing

Seat Dimensions and Vehicle Compatibility
The Cobra Monaco 40th Edition has a slimline design, making it versatile enough to fit inside a wide range of vehicles. While compact, it’s designed to accommodate drivers with a 32–36 inch waist, striking a balance between comfort and snug lateral support.
Main Measurements:
- Shoulder width: 550 mm
- External base width: 510 mm
- Internal base width: 360 mm
- Base depth: 405 mm
- Backrest height: 870 mm
- Base length: 660 mm
- Weight: approx. 10.3 kg
These proportions allow the seat to work well in cars with tighter cabins while still offering the space needed for most drivers.
Installation
All Cobra Monaco bucket seats are designed to give flexibility during installation, as they can be either base or side mounted depending on your setup. For side mounting, the Monaco uses a 290 mm bolt spacing, which is the same as most aftermarket side-mounted bucket seats. This makes it straightforward to pair with standard side mount brackets, giving you a solid and secure fit.
For base mounting, the Monaco uses a 291 mm bolt pattern, which is unique to Cobra. This means the seat will fit directly to Cobra sub-frames and 291 mm sliding runners, allowing for an adjustable installation that works perfectly when you’re using Cobra’s own hardware.
However, many vehicle-specific frames on the market from brands like Sparco, OMP, and Planted Technology are designed with a wider 345 mm bolt pattern, which doesn’t line up directly with the 291 mm spacing on the Monaco. In these cases, you have two options:
- Side mount the seat to gain the wider fixing point straight onto the frame
- Use adaptation plates when base mounting, which bridge the gap between the Monaco’s narrower bolt pattern and the wider frame pattern
This approach is common, as the 345 mm base pattern is the most widely used standard across aftermarket frames. Whether you side mount or use adaptation plates, both methods provide a safe and effective way to install your Cobra Monaco seat securely into your vehicle.
The Cobra Monaco Seat Collection
We stock a wide range of Cobra Monaco bucket seats, with options to suit both daily drivers and motorsport builds. Customers can choose from different trim materials such as Tartan, 3D spacer fabric, nylon/velour fabric, and vinyl, depending on their preference for grip, breathability, and style.
The Monaco range includes FIA-approved versions for motorsport use and non-FIA versions that are ideal for track days or spirited road driving. To cater to different body types, the Monaco is also available in standard and narrow-width sizes (non-FIA only).
For those who want something truly unique, there are also special editions like the 40th Edition, Tartan Edition, and Houndstooth Edition. Each of these adds distinctive styling cues to the classic Monaco design, letting customers find a seat that not only fits their car but also reflects their personality.
Our customer went for the Cobra 40th edition bucket seat with the tartan trim upgrade. We have a listing with the upgrades pre-applied with a range of different tartan designs to choose from. There is also the option to use your own materials, as our customer did, by sending over the material for Cobra to use to make your bespoke seat.

Why Choose the Tartan Trim Upgrade?
Tartan is one of those rare materials that feels instantly nostalgic yet timeless. For retro builds, especially from the 1970s to early 90s, tartan adds the perfect finishing touch. Whether it’s matched to a classic paint colour or used to contrast a clean black interior, the pattern creates a visual link to motorsport heritage and classic rally styling.
Choosing a tartan trim for your Cobra seat also gives your build a more personal and distinct look. No two tartan layouts are exactly the same, and with the ability to supply your own fabric, the possibilities are endless. It’s a great way to inject character into your cockpit while still retaining all the performance and support of a competition seat.
Custom Classic Seats With Real Personality
These Cobra Monaco 40th Edition seats in custom tartan trim are a brilliant example of how a little personalisation can elevate a build. With FIA approval, classic styling, and made-to-order trim options, this seat hits the sweet spot between heritage and function.
Whether you want something that matches your original interior or a seat that feels completely your own, Cobra’s Signature service makes it possible. This pair looked fantastic on their way out of the showroom, and we’re sure they’ll look even better installed in our customer’s build. If you’re after something unique, this is a great place to start.
