Our Verdict

The Lost Horizon is a budget-friendly double camping mattress that aims to deliver comfort without the premium cost of big-name competitors. With almost 4 inches of padding, it offers solid cushioning and decent three-season warmth. In testing, it provided good motion isolation so you don't disrupt your partner, and easy firmness adjustment. It is great for sensitive sleepers. However, it falls short in packability, rolling up substantially larger than many competitor dos, and its self-inflation is weak. While it includes a helpful electric pump and stuff sack, its overall score is mid-pack among tested mattresses, positioning it as a practical value option for car camping rather than a top performer.
REASONS TO BUY
Bag doubles as an inflation pump if needed
Strap keeps the pad from unfurling
Included battery pump
Easy to deflate small amounts of air
Carry strap on the bag and around the pad
And a forgiving sack for messy rolls
REASONS TO AVOID
On the heavy side
Doesn’t pack as small as other double pads
Valves aren’t flush with the mat

Our Analysis and Test Results

Our Experience


We love Exped and NEMO products, but paying $400 can be a lot to ask. So when we saw the Lost Horizon at roughly half the price, we had to try it. Our first impression was delight — it came with both an electric pump and a stuff sack, items often missing from more expensive pads. After camping with it for several weeks, we were impressed. While it doesn't match the premium warmth or packability of the NEMO Roamer or Exped MegaMat, it's an incredibly comfortable, durable, and burly pad that most budget-conscious campers will love.

Comfort

Offers comfortable 4-inch padding that effectively isolates you from rocks, roots, or other ground objects unless they are quite large. Firmness is easily adjustable — the firmer you make it, the less likely you are to disturb your sleeping partner. Overall, it is quiet (much quieter than something like a NeoAir), though still louder than a cotton-sheeted mattress. Self-inflation on a new pad is fairly lackluster and usually improves with time; currently, it does not inflate enough on its own to be truly comfortable. Note that while Nemo claims a maximum thickness of 4.5 inches, it measured closer to 3.9 inches when inflated firmly.

Ease of Use



It is very user-friendly, especially for beginners. The included pump is super helpful for those new to camping or rolling up pads (though it is quite loud). Rotating valves make inflation and deflation straightforward, and the knobs are easy to tighten and loosen. The storage sack doubles as a large inflation bag, so you can still inflate the pad quickly even if you forget the pump. Deflating and achieving a tidy roll takes some practice for novices, but the generous bag easily accommodates a messy one. Overall, it strikes a good balance for real-world use.

Warmth


The Lost Horizon claims an astounding R-value of 13 on Amazon (the highest in this review). We are dubious. We think it is more likely to have an R Value of 6-8. Good for three-season use, but definitely not the warmest pad we have ever slept on. In real-world testing at around 40°F on wet grass with a 40°F sleeping bag and no tent, it performed solidly but still allowed some cold to seep through where the bag touched the pad, especially when rolling over. It felt roughly comparable to the NEMO Roamer Double, with perhaps a slight half-point edge in warmth. Overall, it is on the better end for cold-weather performance.

Versatility

The Lost Horizon camping mattress works well beyond traditional camping. It can serve as a comfortable spot for an afternoon nap, a beach lounger, or a cozy surface for snuggle parties and movie nights. In a pinch, it makes a decent guest bed for friends or family — some people may prefer an elevated frame, but most folks who are open to camping gear won't mind sleeping on it. Air travel is possible if you use it as a carry-on, but it's not ideal due to its size and weight. Overall, it's a versatile pad for both outdoor adventures and casual indoor use.

Should You Buy the Lost Horizon Full Camping Pad?


If you're looking for a comfortable, versatile double camping mattress for car camping, guest use, or casual indoor setups, the Lost Horizon is a solid choice. It offers good 4-inch cushioning, easy firmness adjustment, and strong versatility as a nap spot, beach lounger, or play mat. It's user-friendly with helpful valves and a pump, though self-inflation is weak at first. Overall, it is a great deal, especially since it comes with an electric pump.

What other Camping Mattresses Should You Consider?


The Lost Horizon offers strong value compared to the NEMO Roamer Double, coming in at roughly half the price while including an electric pump and stuff sack—features often missing from more expensive pads. It delivers solid comfort with 4-inch padding and easy firmness adjustment. However, it falls short in packability, rolling up noticeably larger than the Roamer. Warmth is roughly comparable, with the Lost Horizon showing a slight edge in testing, though its claimed R-value of 13 is questionable. Overall, the Lost Horizon is a capable budget alternative but doesn't match the Roamer's refined performance or compact size.

Compared to the Exped MegaMat Duo, the Lost Horizon is significantly more affordable and includes useful accessories. While it provides good comfort and durability for car camping, it doesn't match the MegaMat's superior plushness, warmth, or refined feel. The Lost Horizon is also bulkier when packed and less refined overall. It performs well for the price and offers strong versatility as a guest bed or lounger. Still, serious campers seeking premium comfort and insulation will likely prefer the more expensive Exped MegaMat Duo.
