LOSTHORIZON - Air & Foam Camping Mattress

Exped is the current king of the semi self inflating mattresses but there are other worthy considerations which are more affordable, especially on sale. I went with a Lost Horizon I found on clearance for half price. Probably not as bomb proof as the Exped, but after about a dozen trips this summer it’s going strong without issues. The bottom line is these type of mattresses are exponentially more comfortable than anything else on the market. I will never go back. The only drawback is they don’t roll up small.

I have one of these Lost Horizon mattresses and have used it 10+ times. I'll never go camping without it. [https://www.amazon.com/dp/B09XLHQTXY](https://www.amazon.com/dp/B09XLHQTXY)

This one was a bit out of my price range but I bought one on Amazon by a brand called lost horizon. I feels the same and it’s about half the price. It’s gone on a few adventures with me.

Lost Horizon is great for cold camping, they'll stay fully inflated at below freezing, but you do need a pump to deflate it properly, still the most comfortable camp mattress I've laid on

Goto REI and try a few out! "Self inflating" is a little misleading, as you might still want to blow a few breaths into it to fill it to your comfort level. Klymit are pretty thin and lightweight which are good for backpacking. I've got a CORE brand mattress that is working for me in my RTT. I had a Lost Horizon brand off Amazon but it ended up developing a leak and their Customer Support was unreasonable to deal with so I tossed it. I've heard NEST are super comfy so check them out too.

Bf and I got the lost horizon matress (the double is less than half the price of megamat, including a pump to help deflate) and we are very happy. It‘s 12cm thick and that is the sweet spot. I also tested 8cm thickness and that was not enough. The LH feels like our bed, honestly. Some thoughts: If you get two singles they slide against each other and apart from each other very easily. Dunno how people solve this. I hate the noise that movement creates and it wakes me up more than anything. I am very glad we got the double to not have to deal with that. My bf weighs obly a bit more than me (20kg) and I don‘t feel the matress getting harder when he lies down. It pretty much feels like if I was laying there alone. I think it‘s the thick foam inside. I feel him move but less than I expected bc it’s „like in my real bed“, not like „I’m on a ship of an air matress and we are sinking….“ ;) For sleeping bags: I‘d prefer cotton on the the inside but I am a summer camper who hates the feeling of sythetics on my skin. Don‘t get a mummy, get a double sleeping bag that can be split into two or the other way round two singles that can be connected ;)

I got a lost horizon self inflating mattress and it’s like a whole queen mattress

Sorry I worded that bad I meant it feels like a real mattress not an air one

The Lost Horizon pads are great! Only downside is a bit of struggle rolling them up.

I love the LostHorizon Single for on my cot. Super comfortable, affordable and got it on sale around $100 on Amazon. Not on sale is about $120

Lost horizon on Amazon in cot size. It’s shorter than the other sizes but 30” wide which is sweet. I have two lost horizons and for the money I’m not sure they can be beat

I’ve got two lost horizons paired with ZenBivy. Unbeatable combo

Both. Single for myself and double for when my wife comes or if it’s not going to be cold and I want to sprawl out. My single pad is 28” wide and I no longer feel the claustrophobia of sleeping bags. Highly recommend and i believe there’s a good sale for 4th of July.

Lost horizon has been more than good enough for me

I do the same. The lost horizon is great. I even started just not using the cot and it’s fine.

We just got a Lost Horizon today and man i might use it tonight instead of my normal mattress. Obviously havent used it camping but initial thoughts are that it was worth the 200

Will do! We’re making sure right now that we have no leaks. I love that you can use the bag as a pump. Could piss me off when tryna deflate and roll it back though. But yeah it’s super duper comfy I think we’re gonna get great sleep when we camp going forward

I use a Lost Horizon (basically a half price MegaMat) coupled with a small cot. It's the best option I found when I don't have my camper with a real mattress.

Knockoff exped from Amazon is the way to go IMO. https://a.co/d/ggIxYPx

Air mattresses with Foam do not transfer any movement. Like an exped / lost horizon

We bought the Lost Horizons brand from Amazon. This looks very similar. If it's like that on, it's comfy, needs a little help inflating all the way, and is an absolute pain to deflate and roll up. Also heavy, and big when packed.

I love my 4.5" LostHorizon pad, but it definitely doesn't pack down small, lol. Strictly for car camping.

Lost horizon self inflating sleeping pad.

I use the lost horizon foam air mattress with the Northface dolomite sleeping bag. Very comfortable

I have a Lost Horizon that is basically a dupe for the Exped Megamat. It’s my favorite mattress to use car camping.

We use a combo of lightweight Marchway cots (approx $70) and inflatable air and foam LostHorizon pads (approx $110) all from Amazon. The cots are only about 6" off the ground which can be a bit of a pain, but they work well. The pads are a bit bulky, but very comfortable and warm.

My husband and I use LostHorizon brand foam & air inflatable pads (similar to Exped) on top of lightweight Marchway cots. Our cots are much, much smaller and lighter than our sleeping pads, LOL.

If you consider Exped, please take a look at the cheaper brands on Amazon. For some unknown reason Reddit is obsessed with the overly priced Exped. I have an Exped for my RTT, and two cheaper brands for my cars. They are identical in material and comfort. Hikenture and Lost Horizon, 50%+ cheaper than Exped.

A little late to the party but if anyone ends up back on this thread I just have to say that the Lost Horizons pad is incredible. We've had one for two years and my wife and I agree it's the most comfortable pad we've ever had. I chose it over the Hest. The Exped looks similar but no experience with that one. It is possible to get it back in the bag without the pump but it's a bear. If you dont need to put it away the stuff sack is perfectly adequate for inflation. Only real complaint is the available sizes is a little odd the single is 28" wide, Amazing, but 80" long and doesnt fit in my Tacoma with the camper shell closed. The cot size is 75" and fits perfect but is only 25" wide, which is adequate so I just ordered one for my truck but Id prefer a 28x75 for sure. Your next choice in that length is the twin 38x75. Depending on your application I would just pay close attention to their dimensions.

High R-value sleeping pads help. We’ve tried 2 mats so far that are self inflating. We’re currently using the Lost Horizon 4.5in pad with a R-value of 13. However, I think my favorite was our first, the Stoic double cloud camp bed that’s 3.9in thick with in R-value of 11.5. It gets really firm and stayed pretty firm throughout the night. (Still get a portable inflator, it’s so worth it). We also use flannel sheets and tuck our pad in our double sleeping bag so it’s a nice snug fit. And good camping pillows are worth it… like Klymit. This setup isn’t great for backpacking obviously, but we love it for car camping and when we’re at the campsite for a week. Also, 3 beers in with some s’mores by a fire always makes us sleep so hard lol. Happy camping!!!

LOSTHORIZON is my current mattress and it's incredible. its like 6.5' long but doesnt take up much space and also self inflates but you can buy it with a battery powered air pump as well

That's the pad we use. It's awesome.

LOSTHORIZON Air & Foam Camping Mattress. They fit your budget depending on the size you order. Get the pump; it makes it way easier to deflate and pack. They are very comfortable!

I, too, despise common air mattresses. I have a LOSTHORIZON sleeping pad. Purchased from Amazon. It feels like sleeping on a cloud. The top part of the mattress is made of foam and the rest is self inflating with a valve that flips from inflate to deflate (though I recommend their rechargeable pump to inflate/deflate). It’s only about 4” thickness but they have different thicknesses to choose from, I believe. I have used the LOSTHORIZON sleeping pad for a couple years now and it’s super durable and the air inside does not seem to fluctuate! Definitely one of my favorite camping purchases I’ve made.

I have the lost horizon, full. I'm not exaggerating when I say I can't imagine a pump being more effective than the one included with the lost horizon. It deflated the mattress to pancake flat in seconds - I don't know what better even means in this context. Even if the exped is somehow faster, I'm not sure that 9 seconds instead of 10 is worth the price difference. I have a (obviously pathological, obviously irrational) belief that there is a "right" choice in every gear category, and an equally pathological need to have that "right" gear. The lost horizon satisfies.

Re: the pad itself, I have the full/double. I'm 6'2" 240lbs and don't bottom out.

Another vote for the Exped Megamat and a cot. I can sleep better on mine than I do in most hotel rooms. Having a cot to get the sleeping platform up off the ground will make long-term use a lot more tolerable. Something about being able to sit on your bed and put your boots on in the morning is so comforting.... If you don't want to spring for the Exped Megamat, check out the copies on Amazon from [CORE](https://www.amazon.com/CORE-Inflating-Mattress-Inflatable-Sleeping/dp/B0CJZSXCGG) and [LostHorizon](https://www.amazon.com/LostHorizon-Inflating-Sleeping-Mattress-Inflatable/dp/B09XLGQ6GR). I have used both and they compare very favorably at a lot lower price tag.

Yeah I’m so impressed with these pads. Can’t imagine a pad being much better. I have the Lost Horizon double and two Sportneer singles. They are either made in the same factory or someone is doing a real good job of copying, but whatever, they are both great

It’s expensive but I swear by the losthorizon 4.5inch self inflating bag. Most comfortable of the ~10 bags I tried and super easy to set up/pack

Lost horizon on amazon, same as exped for 1/3 the price. We’ve had ours for 3 years now and still good. Just make sure you get a pump that’ll let you inflate and deflate to the bag because you do not want to be doing it manually.

Lost horizon. It’s amazing we even use ours as a mattress topper at home. Use a pump to deflate.

Lost horizon is the same thing as exped. Probably same Chinese suppliers… I have lost horizon and we love it. It feels exactly the same as the expeds I’ve tried at REI.

Lost horizon been good to me for the last 3 years

I’ve been using my lost horizon pad for I don’t know four years now it’s been perfect

I can't say much about durability yet, but my Lost Horizon queen mattress was extremely comfortable on my 2 week camping trip. I shared it with my 120lb Great Pyrenees mix, and it survived a few scratches from the dog without any issues. 

I have one of these and i absolutely love it, my girlfriend does too. It doesn’t transfer movement like an air mattress and its is a good thickness where you are comfy but also nice and flat so your back doesn’t get all messed up from sinking into it

Honestly, I returned my ExPed for my Lost Horizon mat. The cost/value was more important to me and I still sleep perfectly on it.

How do you keep your lost horizon from losing air specifically from the 2 way valve? Mine always leaks overnight and the company is stumped as to why it happens. Just wondering if you have any extra advice to make sure the seal is seated correctly!

I did the soap and water test and it's only coming from the valve. They sent me like 15 more valves and of course they all do this to me. 😭 The sleeping pad is brand new, too! Edit to add: thank you for replying to me and trying to help!
