Prototype V01: Edge Refinement & Comfort Evolution

Testing Overview

Our first production-ready prototype, PillowFlow V01, entered its second round of on-road testing this week — across a mix of vehicles and seat configurations to challenge the design under realistic driving conditions.

To ensure accuracy, we rotated drivers through five test vehicles:

• 2022 Tesla Model Y – minimalist seat design, firm side bolsters

• 2019 BMW 3 Series – moderate bolsters, medium foam density

• 2021 Toyota Camry SE – everyday comfort seat

• 2020 Ford F-150 – large seat base, longer cushion profile

• 2023 Hyundai Tucson – compact crossover seat contour

Each vehicle offered a different geometry and seat-edge angle — exactly what we needed to validate how PillowFlow adapts across platforms.

The Finding: Edges Too Rigid

While the internal wedge geometry performed as expected (consistent thigh lift and pressure relief), the perimeter edges of V01 proved too firm for longer drives.

After the first 90 minutes of driving, testers reported:

• Slight localized pressure near the outer thigh area in narrow seat designs (BMW 3 Series, Tesla Model Y).

• A need for softer edge transitions to eliminate awareness of the cushion boundary.

• Excellent stability, but reduced comfort when shifting leg positions in tight pedal zones.

Our data from sensor mapping confirmed this. Pressure distribution remained uniform in the central zone but spiked 12–18 % higher near the right and outer edge in firmer seats.

Insights and Adjustments

These results point to one clear improvement area: edge contour refinement.

✅ Next Iteration Goals (V02):

• Introduce a progressive edge taper — softening the transition zone without sacrificing structure.

• Integrate a dual-density gradient near the periphery for adaptive comfort.

• Modify underlayer geometry to keep anti-slip performance intact.

• Preserve PillowFlow’s stability and “locked-in” feel on various seat fabrics.

We’re also testing an updated surface finish — a satin-matte coating that subtly reduces friction while enhancing breathability during long-distance use.

Real-World Impact

Drivers consistently described the ergonomic effect as “relaxing but firm” — a critical balance we want to maintain. Once the edge rigidity is tuned, we expect:

• Even smoother thigh support across dynamic motion (pedal transitions).

• Improved lateral comfort for smaller-framed drivers.

• Extended comfort window beyond 2 hours of continuous driving.

Next Steps

Prototype V02 will enter testing next week with the revised edges and compound gradient implemented. We’ll repeat the same test matrix (five vehicles, identical routes, same drivers) for comparison.

Each iteration brings PillowFlow closer to final production readiness — fine-tuning the micro-comfort details that make macro-level differences every minute you drive.
