Second night into a four-night trip at Wilsons Prom, our cheap blow-up air bed lost half its air by midnight. Not a slow leak either — just enough seams and valves flexing under body weight that it quietly went flat. Woke up on a groundsheet with a rock somewhere under my hip. That was the trip that got me to actually compare self-inflating mattresses against the standard pump-up air beds properly, instead of just grabbing whatever was cheapest at the shops.
If you’re trying to decide between a self inflating camping mattress and a traditional air bed before your next trip, here’s what actually matters — not spec-sheet stuff, but what happens on the ground at 11pm when you’re tired and the tent’s already up.
What’s the real difference?
A self-inflating mattress has open-cell foam inside a sealed fabric shell. Open the valve, the foam expands and draws air in on its own — you just top it up with a few extra breaths. A traditional air bed is just an air chamber; you’re doing all the inflating yourself, by pump or by lung.
- Self-inflating mat: foam core, insulated, holds shape, smaller pack size, moderate weight
- Air bed: hollow air chamber, no insulation of its own, bulky when packed flat, needs a pump, cold underneath
- Foam-only mat: no inflation needed, warm, but bulky to carry and less cushioning
Comfort: where the foam earns its keep
The foam inside a self-inflating mat does two jobs — it stops you feeling every root and pebble, and it traps a layer of air so you’re not losing body heat straight into the ground. Pure air beds feel plush at first but they conduct cold badly. Anyone who’s woken up freezing on an air mattress in autumn knows this — you can feel every degree the ground is stealing.
Something like the Self Inflating Camping Mattress in grey sits in that sweet spot — enough foam density to smooth out uneven ground, but still packs down small enough to strap under a pack or slide into the back of the car without eating your whole boot.
Size matters more than people think
Standard single mats run around 180-190cm, which is fine for most adults but tight if you’re over six foot or you like to sprawl. This is the one thing people forget to check before buying — a mat that’s 10cm too short means your feet hang off the end all night, which sounds minor until it’s happening at 3am on rocky ground.
The 187cm Self Inflating Mattress gives taller campers that extra bit of length without stepping up to a double, which matters if you’re trying to fit two singles side by side in a smaller tent.
Setup speed and effort
This is where self-inflating mats win outright. Undo the valve, unroll it, walk away and set up your tent — by the time you’re done, the mat’s mostly inflated and you just top it off with a couple of breaths. Air beds need a pump (battery or foot), which is one more thing to pack, one more thing that can break, and one more job after a long drive when you’d rather be sitting down with a coffee.
Durability and punctures
Neither type is bulletproof, but self-inflating mats tend to hold up better against gravel and twigs because the foam gives some structure — a small puncture doesn’t collapse the whole mat instantly the way it can on a fully air-filled bed. Both types come with repair patches, and it’s worth actually packing yours rather than leaving it in the box at home.
- Clear the ground of sticks and sharp stones before laying either mat down
- Use a groundsheet under the tent as extra protection
- Store mats loosely rolled, not tightly compressed, over winter — keeps the foam from losing its bounce
- Air dry fully before packing away if there’s any condensation
Which one for which trip
For weekend car camping where weight isn’t an issue, either works, but self-inflating still wins on warmth and comfort per kilo. For anyone hiking in, the smaller packed size and lighter weight of a self-inflating mat makes the decision easy. Air beds still have a place for backyard sleepovers or short stays where insulation doesn’t matter and you’ve got power for a pump.
If you’re camping as a family, sorting the adults’ mats is only half the job. Kids need their own gear that actually fits them — a sleeping bag sized for an adult just bunches up and lets draughts in around a smaller kid’s shoulders. The Kids Sleeping Bag Set of 2 at 172cm is built for that, and pairing two of these with a couple of self-inflating mats covers a family tent without anyone freezing or rolling off the edge.
What I’d actually pack
For most Australian camping — caravan parks, national park sites, the odd hike-in trip — a self-inflating mat beats a traditional air bed on almost every measure that matters once you’re actually lying on it at night. The only case for a straight air bed is short trips with power access and zero concern about cold ground. Otherwise, the extra warmth, faster setup and smaller pack size make the self-inflating option the one that gets used trip after trip, not left in the shed after one cold night.
