Sleeping in a pop-top roof or roof tent comes with one unavoidable challenge: limited space.Unlike standard campervan beds, pop-top and roof tent sleeping areas must balance comfort, mattress thickness, foam firmness, and roof clearance.
Our pop-top and roof tent mattresses are designed specifically for these environments — offering proper support without preventing the roof from closing.
Pop-top roofs and roof tents place very different demands on a mattress compared to fixed campervan beds.
In these spaces:
Mattress thickness is restricted
Softer foams can bottom out quickly
Excess weight can affect roof mechanisms
The roof often needs to close with bedding left in place
For this reason, foam choice and construction matter just as much as comfort. A mattress that feels soft in a showroom can perform poorly once installed in a roof space.
If you want the technical explanation behind this, it’s covered in more detail inRoof tents & pop-tops – when physics says no.
In a pop-top or roof tent, the goal isn’t maximum softness — it’s controlled support.
Thinner mattresses need:
Higher-density or firmer foam cores
Even weight distribution
Minimal long-term compression
This is why many pop-top mattresses are intentionally firmer than standard beds.The result is better spinal support, improved durability, and fewer issues when closing the roof.
Firm foams are often recommended for pop-top roofs because they:
Perform better at reduced thicknesses
Prevent “hammocking”
Offer long-term durability
Allow roofs to close cleanly
For simple, ready-to-fit options, many customers start with aPop-Top Roof Mattressor aPop-Top Roof Tent Mattress,depending on their setup.
Memory foam can significantly improve comfort, but works best:
As a thin comfort layer
Paired with a firm base
When removable if roof clearance is tight
This is why many customers add aPop-Top Memory Foam Mattress Topperor chooseCustom-Size Memory Foam Toppersthat can be stored separately when not in use.
Advanced foams such as GelFlex can:
Improve pressure relief
Increase airflow
Reduce heat build-up
These are popular with customers who regularly sleep in their pop-top or roof tent and want better comfort without increasing mattress thickness.
There’s no single “correct” thickness for pop-top mattresses.The right choice depends on:
Roof design and hinge mechanism
Whether bedding stays in place when closed
User weight and sleeping position
Foam type used
As a rule of thumb, firmer foams allow thinner mattresses to remain comfortable, while softer foams need more depth.
Pop-top and roof tent sleeping areas are more exposed to condensation and reduced airflow.
To help manage moisture, many customers add aMoisture-Reducing Mattress Spacerto improve ventilation beneath the mattress and reduce damp build-up.
Breathable, removable, washable covers are also strongly recommended for roof-mounted sleeping areas.
Pop-top roofs and roof tents vary widely in shape and size.For the best fit and maximum use of available space, many customers choose aCustom-Size Pop-Top Roof Mattressmade to their exact measurements.
These are ideal where:
Roof shapes are irregular
Factory mattresses don’t fit cleanly
Headroom is especially limited
How thick should a pop-top mattress be?It depends on roof clearance and foam type. Firmer foams perform better at reduced thicknesses.
Can I leave the mattress in place when closing the roof?Often yes — provided total thickness stays within the roof’s tolerance.
Is firm foam better than soft foam in a roof tent?Generally yes. Firm foams give better support in thin mattresses.
Can I upgrade comfort later with a topper?Yes. Many customers do exactly that.
