🏕️ Roof Tent Mattresses

🚙 Sleep Easy in the Sky

Roof tents are brilliant for off-grid freedom — but let’s not pretend the sleep setup is luxurious. Most rooftop tent mattresses are thin, cheap, and not made for a proper night’s kip.

At Foam4U, we build bespoke roof tent mattresses that fit your exact setup – whether it’s a hard shell RTT, soft shell foldout, or custom rig. Cut to size, made in the UK, and built to transform your sleep.

🧠 Why Upgrade Your Roof Tent Mattress?

Let’s be real:

  • 💤 Factory-fitted mattresses are rarely more than 3–5cm thick

  • 🌬 Poor breathability means heat build-up and condensation

  • 🧱 You can feel the base – not ideal after a long day on the road

Fix It With Foam That Works:

  • ✅ High-density foam (like RX39 or RG50) for lasting support

  • ✅ Memory foam toppers for extra comfort in limited space

  • ✅ Ventilated base mesh to prevent mould, damp, and sweaty nights

Whether you're bivvying on Dartmoor or touring the Alps, you’ll feel the difference on night one.
