Choosing the right seat-bed system is one of the most critical decisions in any campervan conversion. It impacts everything from safety and comfort to budget and layout.
In our industry, the debate often centres on premium, certified systems like the Scopema RIB Altair/Neptune and the more traditional Rock ‘n’ Roll (R’n’R) bed. Both are excellent options, but they serve different priorities. This guide simply lays out the facts, features, and trade-offs to help you decide which is right for your build.
🛡️ Fact 1: The Safety Standard (M1 Crash Testing)
This is the biggest differentiating factor and often dictates the price premium of the RIB system.
| Feature | RIB Altair/Neptune (Premium) | Rock ‘n’ Roll (Budget/Custom) | Supporting Data |
| Crash Testing | M1 Certified & TÜV Approved. | Variable. Some models are M1-tested (often called ‘pull-tested’), but many generic or DIY R’n’R beds are not certified. | M1 testing simulates a 30-mph collision to confirm the integrity of the frame, fixings, and seatbelts (ECE Regulation 14.09). |
| Seatbelts | Integral 3-point belts are standard, tested with the seat. | Variable. Belts may be integrated, bolted to the floor, or non-existent in older/DIY models. | An M1 certificate confirms the entire system (seat and anchors) is safe for passenger use. |
| Child Safety | ISOFIX is now standard on all new RIB Altair models. | Rare/Non-existent on generic R’n’R frames. Only available on specific, M1-tested R’n’R brands. | ISOFIX provides a simpler, safer method for securing child seats. |
The Takeaway: If you plan on regularly carrying passengers, especially children, in the rear of your van, an M1-certified seat (like the RIB) provides the highest level of proven safety and peace of mind.
🛌 Fact 2: Comfort and Mechanism
The fundamental difference in how these seats transform directly affects sleeping comfort and ease of use.
| Feature | RIB Altair/Neptune (Premium) | Rock ‘n’ Roll (Budget/Custom) | Supporting Data |
| Sleeping Surface | Perfectly Flat. The seat cushions flip over, meaning you sleep on the smooth, flat underside. | Contoured/Lumpy. You sit and sleep on the same cushions, often resulting in an ‘A-frame’ or lump where the hinge is. | Flat sleeping surfaces are scientifically proven to be better for spinal alignment and long-term sleep comfort. |
| Seat Comfort | Ergonomically Contoured and shaped like a passenger car seat. | Typically, flat bench seating, which is less supportive for long journeys. | Ergonomics and shape are key considerations for passenger comfort during long drives. |
| Mechanism | Smooth, two-stage lever system. Quick and easy to convert. | Simple hinge/slide. Can sometimes require more effort or cushion removal, depending on the design. | The RIB’s flip-over mechanism creates a large, accessible “boot” area when the seat is up. |
💰 Fact 3: Cost and Customisation
Budget and the final aesthetic are major drivers for many converters.
| Feature | RIB Altair/Neptune (Premium) | Rock ‘n’ Roll (Budget/Custom) | Supporting Data |
| Cost (Supply Only) | High Premium. Starting price is significantly higher due to complex engineering and certification. | Wide Range. Basic frames are significantly cheaper, while certified, branded R’n’R units can approach RIB pricing. | Anecdotal evidence suggests the price difference between a certified R’n’R, and a RIB can be £1,000 to £1,600+ (depending on specification). |
| Customisation | Excellent factory customisation (widths, sliders, heights, OEM fabrics). | High level of DIY Customisation for frame size, upholstery, and installation height. | R’n’R frames are often more open source for welding/custom fabrication by specialist upholsterers. |
| Resale Value | Adds Significant Value. Professional converters favour RIB, which signals a high-quality build to buyers. | Neutral Value. A non-certified R’n’R is a cost-saver; an M1-certified unit helps maintain value. | Buyers typically equate M1 certification and RIB branding with a premium conversion. |
⚖️ The Conclusion: Your Conversion, Your Priority
- Choose the RIB Altair/Neptune if your priorities are:
- Maximum Safety: Non-negotiable M1/TÜV certification and ISOFIX.
- Maximum Comfort: Flat sleeping surface and contoured passenger seating.
- Best Resale Value: Premium brand recognition.
- Choose the Rock ‘n’ Roll Bed if your priorities are:
- Budget: Saving money on the initial frame cost.
- DIY Freedom: High level of customisation and simpler fabrication.
- Occasional Sleeping: You use the bed more for storage or occasional overnight stops without rear passengers.
If choosing R’n’R, always look for a brand with M1 certification if you plan to carry passengers.
The RIB Altair/Neptune is an investment in safety and comfort engineered by Scopema; the Rock ‘n’ Roll bed is a versatile and cost-effective foundation that offers the essential seat-to-bed functionality. Both have a firm place in the campervan community.
