Modular spring‑pod systems create a flexible, ventilated support layer beneath a slim pop‑top mattress. They improve comfort, reduce pressure points, increase airflow, and help prevent moisture build‑up, all without affecting roof closure. Paired with our Van & Bus foam mattress, they deliver a noticeably better night’s sleep in Stealth B2B pop‑tops.
Comfort in a pop‑top isn’t just about the mattress. It’s about what sits underneath it. That’s where modular under‑mattress spring systems come in, the type commonly known through products like Froli or Cube.
These systems create a flexible, ventilated support layer beneath your mattress, turning a compact pop‑top bed‑board into a genuinely comfortable sleeping space.
A spring‑pod system is a grid of individual plastic spring modules that clip together to form a base. Each module flexes independently, creating a suspension effect under a foam mattress.
Instead of sleeping on a solid bed‑board, you sleep on a surface that:
This makes them ideal for compact sleeping environments like pop‑tops, campervans, and boats.
Pop‑tops require slim mattresses so the roof can close safely when the mattress is stowed, not taking up storage space within the van. Slim mattresses need good support underneath. Spring‑pod systems add the “give” and contouring that foam alone can’t provide.
Pop‑tops naturally trap moisture overnight. A spring‑pod system lifts the mattress off the board, creating constant airflow that helps prevent:
This is especially important for year‑round users.
Our foam mattress is engineered to compress safely when the roof shuts. A spring‑pod system sits comfortably underneath without affecting roof closure or seals.
Because each module flexes independently, you can tune the feel by adjusting spacing or mixing softer/firm modules. This creates better shoulder relief and hip support, something a fixed board can’t do.
Fitting a spring‑pod system is simple:
No adhesives. No specialist tools. No modification to the roof.
With a spring‑pod system underneath and our foam mattress on top, you get:
All while keeping the mattress slim enough to store in the roof, no extra lifting, no extra faff.
If you choose a spring‑pod system for your Stealth B2B pop‑top, our team will fit the system directly to the bed‑board during your build.
This ensures correct placement, optimal support, and no risk of mis‑alignment.
Once fitted, the system can be easily re‑configured or tailored to suit individual comfort preferences, adjusting firmness zones as needed.
