Lost Horizon Air & Foam Camping Mattress
- Best for:
- Front-country car or truck camping, overlanding, RV/cot setups and couples/families who want near-mattress comfort at a budget price
- Skip it if you want:
- Weight- or space-conscious activities such as ultralight backpacking, long-distance hikes, or very small tents where a large queen pad won't fit
Main tradeoff: Very heavy and bulky for a two-person pad (queen ~17.6 lb), so poor packability

About the Lost Horizon Air & Foam Camping Mattress
The Lost Horizon Air & Foam Camping Mattress is a plush air-and-foam hybrid that has become the community's favorite value alternative to premium car-camping pads like the Exped MegaMat and NEMO Roamer. A supportive foam top over an adjustable air chamber delivers 4.5 inches of cushion; it self-inflates, with an optional pump to fine-tune firmness. This is the single (80 x 28 in, 9 lb) — the most popular size — and the mattress is also offered from a slim single up to an 80 x 60-inch queen. The tradeoff is weight and pack size. At 9 lb it is heavier and bulkier than a slim self-inflating pad, relying on an air-and-foam build rather than a compact foam core. For front-country car camping, where you drive to the site, most owners consider that a fair trade. What campers are saying (from r/camping and r/CampingGear): owners repeatedly call it the most comfortable camping mattress they have used, with several saying it beats their bed at home, and praise it as easy-inflating, firmness-adjustable, and kind to side sleepers. It is most often recommended as the cheaper-but-equal alternative to the Exped MegaMat (“every bit as good as the Exped, grab it”), and several note that with a pump to evacuate the air it actually rolls down smaller than tri-fold foam mattresses. The main caveat raised: at least one multi-year owner reported the mattress developing air leaks through the fabric after about two years, so long-term durability is worth watching.

Questions (6)
- Is it worth the price over cheaper alternatives?
- For frequent car-campers or anyone prioritizing mattress-like comfort, the Lost Horizon offers strong value compared with premium two-person pads — you get similar plushness and included pump/bag for a fraction of the cost; if packability and weight matter, a lighter, more expensive pad may be a better choice.
- How does it hold up long-term?
- Most owners report solid short- to mid-term durability, but isolated reports exist of valve or seam leaks after extended use; handle valves gently, use a groundsheet, and keep proof of purchase in case of replacement needs.
- What size/capacity should I get?
- Choose the size that fits your tent or vehicle space: queen is 80×60″ (supports up to 500 lb) for two adults; double/full and single/cot sizes are available with lower stated maximum supported weights.
- Can I use it in the rain or for winter camping?
- Use it inside a tent with a footprint or under a tarp for rainy trips — the pad itself is not waterproof and the foam will absorb water; for winter camping it can be warm with a proper sleeping bag, but independent testing suggests it functions as a 3-season pad rather than a guaranteed 4-season option.
- How do I clean and maintain the pad?
- Wipe off dirt, air-dry thoroughly before storage, store deflated in a cool dry place, avoid leaving inflated in hot sun, and patch punctures/valve leaks with appropriate repair kits if needed.
- What comes in the box?
- Options include pad-only or pad + pump kits; kits typically include the pad, a pump sack (manual inflator) and a storage/stuff sack; an AC/battery pump may be sold separately or in some bundles.
