If you’ve been camping long enough to know that a bad night’s sleep ruins a good trip, the Zempire Monstamat Twin has probably crossed your radar. It’s one of the most talked-about camping mattresses in the Australian market — and for good reason. But is it the right choice for you?
This guide covers everything you need to know — specs, real user feedback, how it compares to the competition, and who it’s best suited for.

What Makes the Monstamat Twin Stand Out?
😴 Exceptional Comfort
The 30D super stretch ripstop polyester surface moulds to the contours of your body, giving it a memory foam-like feel that’s rare in a self-inflating mat. At 10cm thick it sits well above most competing mats in its price range and provides genuine full-body support — not just cushioning.
The 3D vertical sidewall construction allows the internal foam to expand fully, and the expanding sidewalls reduce surface pressure for a more comfortable sleep. Side sleepers in particular report no hip or shoulder pressure issues — a common complaint with thinner mats.
🤫 Minimal Partner Disturbance
The no-noise surface fabric and wide double format (132cm across) means couples can move around in the night without disturbing each other — a big deal on longer trips. The surface doesn’t crinkle or rustle like older style PVC air mattresses.
🌡️ Outstanding R-Value
An R-value of 10.5 is genuinely impressive. Most budget camping mats sit between R1 and R3 — barely adequate for warm weather camping. The Monstamat Twin’s R10.5 rating means it performs well in cold Australian nights, high altitude camping, and all four seasons without needing an additional thermal layer underneath.
⚡ Self Inflating
Open the valve and the cross-cored foam draws air in automatically. You can add a few extra breaths or use a pump to firm it up to your preference. The 360° high volume valve makes both inflation and deflation fast and easy.
What Are the Downsides?
Comfort-wise this mat is excellent — but there are some real-world issues worth knowing about before you buy.
⚖️ Weight and Pack Size
At 6.03kg it’s not a lightweight option. This is a car camping and 4×4 mat — not something you’d carry on a multi-day hike. If you’re camping out of a vehicle, swag, or rooftop tent this isn’t an issue. If you’re carrying your gear on your back it’s a dealbreaker.
Packing it down also takes some effort. Zempire recommends rolling from the end without the valve, pressing firmly, unrolling and repeating a few times before folding in half and rolling again. A pump helps significantly with deflation. Some users note this is the most frustrating part of owning the mat.
🔧 Valve Durability Concerns
This is the most consistent criticism in user reviews. Some owners have reported valve seal failures after moderate use — air slowly escaping around the valve housing rather than through the valve itself. Zempire has a 2-year warranty in place, but there have been reports of warranty claim difficulties when purchased through third-party retailers. If you buy one, purchase directly from Zempire AU or a major authorised retailer to ensure warranty coverage is straightforward.
📦 Storage Recommendation
Zempire recommends storing the mat inflated when not in use to preserve the foam. This isn’t practical for everyone — it takes up significant space. If you can’t store it inflated, just make sure the valve is fully open when stored rolled up so the foam can breathe.
How Does It Compare?
Zempire Monstamat Twin vs Exped MegaMat 10 Duo
These two are the most commonly compared premium double camping mats on the Australian market and it’s a genuinely close contest.
• Comfort: Both are exceptional — Exped edges it slightly with a more consistent inflation and firmer feel
• R-Value: Monstamat 10.5 vs MegaMat 10 — essentially equal
• Weight: Similar — both around 6kg for the twin/duo version
• Durability: Exped has a stronger long-term reputation for valve and seam reliability
• Price: Monstamat is generally more affordable in the Australian market
• Pack down: Both require effort — Exped is slightly easier to roll consistently
Verdict: If budget is a consideration, the Monstamat Twin offers comparable comfort at a lower price point. If you want maximum long-term reliability and are willing to pay more, the Exped MegaMat edges ahead.
Zempire Monstamat Twin vs Darche Cold Mountain 1400
The Darche Cold Mountain 1400 is a popular Australian alternative at a lower price point. It’s comfortable and well-built, but at 7.5cm thick and with a lower R-value it doesn’t match the Monstamat Twin for insulation or that memory foam-like surface feel. For warmer weather camping the Darche is excellent value — for cold nights and all-season use the Monstamat Twin is the better investment.
Who Is the Monstamat Twin Best Suited For?
✅ Great choice if you…
• Camp as a couple and want a shared double mat
• Camp out of a 4×4, camper trailer, or caravan
• Camp in varying conditions including cold nights
• Prioritise comfort and a good night’s sleep above all else
• Want a mat that works on a tent floor or on top of a stretcher
❌ Not ideal if you…
• Need a lightweight packable mat for hiking or backpacking
• Have limited storage space at home for a large inflated mat
• Camp exclusively in warm weather and don’t need a high R-value
Where to Buy in Australia
The Zempire Monstamat Twin is available through the following Australian retailers:
👉 Zempire AU — Official Store (buy direct for best warranty support)
👉 Snowys Outdoors (authorised retailer — free delivery Australia wide)
👉 BCF — Boating Camping Fishing (available in store and online)
Final Verdict
The Zempire Monstamat Twin is one of the most comfortable self-inflating camping mats available in Australia. If comfort is your priority and you camp out of a vehicle, it belongs on your shortlist.
The memory foam-like surface, outstanding R10.5 insulation rating, and double-width format make it genuinely hard to beat for couples camping in Australian conditions. The main concerns — valve durability and pack-down effort — are worth knowing about, but don’t outweigh the comfort benefits for most campers.
Buy from an authorised Zempire retailer to ensure your warranty is honoured, and pick up a Monstapump to make deflation and pack-down significantly easier.
Happy camping! 🏕️
