Just what I wanted, but kind of wish I had gotten the double now.
I have a lot of time and experience outdoors from backpacking using minimal or no sleeping pad depending on the terrain and weather to trying a bunch of different name brands (Nemo, REI, etc). This definitely is not for back packing. It is for car camping, meaning drive to the spot and maybe hike a quarter mile at most, my campsite this weekend was 100 feet from my car. Having said that, it is quite big and has a bit of weight but not horrible. I opted for the manual inflation/deflation but may opt for the pump down the road. Inflation was a breeze with the bag provided, took maybe 2 minutes. I tried the self inflation mode but got impatient after finishing up setting up most of camp 15 minutes later. I will say the self inflation mode will work much better the second time you use it. Comfort was amazing. I can honestly say I slept almost as good as I do in my own bed. Normally after a camping trip I'm so exhausted from poor sleep the I need a day to recover, not the case this time. Deflation and storage- definitely takes a bit more effort than I had anticipated but not horrible. I did a tri-fold opened the valve got a lot of air out put the valve on deflate mode then squished out as much air as I could, rolled it up rinse and repeat about 3 times. (this is why I am thinking of getting the pump at some point. I had a big double from another camping company and put this up there with comfort, higher in set up. I really didn't want to spend $300-500 so when I read the reviews on this one I decided to give it a try and I was impressed and very satisfied with my purchase and the price. I highly recommend this for comfort camping, very wide, very long, and super comfy. I bought a second for my son.

Super comfy, high value for the money.
The thing I hate about all these self inflating mattresses is that nobody does a good job of describing exactly what they feel like, and because of that I didn't want to spend half my paycheck on more expensive options. Well I'm going to try to tell you what they are like. First, the foam on the inside is not super dense. Its really just there to help give it some structure for inflation. If you're using it with a cot and it deflates there is enough foam that you're not gonna be totally uncomfortable, but you wouldn't ever purposely run this pad without it being inflated and if you're on the ground and it deflates you'll be sorry it did.. Now there seems to be two mechanisms that make this comfortable. 1. Is that the main fabric body of the pad is much stretchier than your typical backpacking inflatable pad. That coupled with the interior foam structure gives it a nice plush bouncy feel that countours better to your body. 2. There is a thin layer of egg carton memory foam sandwiched between two layers on the top (also I think this is the mistake the other video reviewer left about it "leaking everywhere" I'm betting that top layer of fabric is not part of the sealed air compartment, giving it more comfort and he's just seeing air bubble up from the foam) I've tried almost every sleeping pad you can think of for elk camp. Many major brand backpacking pads. Those 3" memory foam pads you can find here on Amazon. Paco pads. This is the first time I've used one of these style pads, most of them are just too expensive to justify rolling the dice on without knowing how comfortable they are. Out of everything I've tried this is the most comfortable. Not quite as comfy as the bed at home, but you're not going to get much closer. Also inflation is a breeze even without the electric pump. Most people I see reviewing this brand on YouTube seem not to have ever used this style of bag pump. The trick is to blow into it from a few feet away. Lots of air will rush into it filling it up all the way, only needing 3-4 pumps to fill it up. (The Nemo pads use a similar system and have videos on how to do this). Deflation is actually easier than most people make it out to be, some minor effort and its back to its factory size roll. but I have the single, I'm sure larger sizes are a pain though. My sleeping bag did not make a lot of noise with the fabric, however the bottom of the pad rubbing up against my taught cot fabric did make noise, still not as bad as the plastic bag sound of most sleeping pads. Ive only used it for one night, but I'll be putting a full 7 nights on it in a couple of weeks. If I haven't updated since then you can bet it held up and lasted well. Very happy with the value for the money.

Absolute AAA+ comfy, quick to inflate, durable
We got this for car camping & ordered an electric pump to deflate it. I recommend NOT getting an off-brand pump, as ours didn’t work at all. We deflated it the old fashion way as per recommendations and it actually was fine - my hunny is pretty strong/200lbs and he was able to sit & roll it up (using his weight). Worth it to order the “electric” version for $20 more and it will come with a tiny portable pump for deflation. It inflates perfectly, as the other reviews stated, we opened it when we got to camp and in hours it was ready, and we didn’t need to add extra air at all. It’s big, don’t get me wrong, maybe about the size of those old fashion canvas sleeping bags. Perfect for car camping. We camped twice with it so far and our nights sleep was SO COMFY and well rested. We have a king size temperpedic bed at home, I’m 5’3 and he is 6’1 (and we have an infant), and we felt it was plenty of space and super comfortable. It filled our 4 person tent nicely with some room for a baby mattress and our gear. Highly recommend at such a good price. This is a wonderful spare bed and I’d even use it for guests if we need it.

So comfortable for camping/glamping!
I have the smaller blue one (75" x 25" x 4.5") and my husband has this one in brown that's longer and wider. They are pretty heavy so definitely not for hikers, but we can move them the several feet from the car to a tent pad just fine. We've been popping them on top of the ($67 here on Amazon) ultralight Marchway camping cots and it results in an easy to use, very comfortable sleeping set up. I don't have as much room side-to-side, but it feels very similar to my nice bed at home. Now that we've traded in our 4 man dome tent for a taller 6 man tent, we might eventually go for taller cots, but as I read through the reviews, I'm really not sure the taller cots will be as comfortable and easy to set up as the ones we already have? (I would welcome more storage space underneath and something a little easier to sit on and get in and out of, however.) The R value on these pads is 13 and it has made a nice difference on cold nights when we're up in the mountains. The kids just use therma-rest type pads on their ultralight cots and they have mentioned being terribly cold on some of their overnights. We've been snug even down to near freezing temps when we're in our bags on these pads. They pretty much self inflate, but hubby has an easier time than I do deflating them by using his weight to push the air out as he rolls up the pad. We also have the Lost Horizon pump. It makes fast work of inflating and deflating the pads, but I'd say it's not totally necessary. They roll up well and fit into the included bags which have a nice roll-top design that seems to keep them secure from bugs, dirt, etc. If you camp as we do, where it's only a few feet from your vehicle to the tent, I highly, highly recommend these. We bought these two years ago and they've been wonderful for us!

Self destructed after a couple uses
Update. After my initial review the company reached out to me and offered a replacement. I’m still concerned it may leave me sleeping on the ground in a future camping trip, but I appreciate their great customer service, and it is a very comfortable and well made mattress. Comfortable, seemingly great quality, easy to inflate, easy to roll back up, and nice storage bag. But only made it through 2 trips before it wouldn’t hold air. The inner part of the valves tear up the membrane from inside and it leaks a lot around both valves now. Seems like it would be a great mattress if it never had to be rolled up again.

Very comfortable.
This is an excellent product. I got this to replace my full size Nemo Roamer, and figured I would take a chance on a well reviewed but less expensive product. It is a bit heavier than the Roamer, which I was shocked by, comsidering it is a smaller mattress, but this is due to it having more robust padding. I have been sleeping on it for about a week on the floor of my toddler's room, and find it to be very comfortable. My bed has a purple mattress which is the most comfortable mattress I have ever slept on, and I daresay, this is pretty close. It feels like a sturdy mattress. It mostly self-inflates on its own, and the carry bag (like other similar products) acts like a pump so you can add more air if needed. It is also so much more comfortable than those large bulky air mattresses that you get at big box stores. It is easy to set up, and honestly, the electric pump they sell would make it easier. It also just takes a few quick tries to get the air volume exactly where you would want it, as with any mattress. It doesn't get too warm, seems to disburse my bodyheat well. Overall, I love this and can't wait to actually use it for camping.

Best air mattress I have slept on!
I have been sleeping on this now for 1.5 yrs as a full time rver, and it's one of the best things I have purchased! It is absolutely the most comfortable mattress and I get an amazing night's sleep. I like a firm, supportive mattress, so I top this with a 2" memory foam topper and it is perfect. I think it would be great for a glamping trip in a tent as well! The carrying case doubles as a manual pump and fairly easy to use. I would love to have a second one for outdoor use.

Super comfortable!
This mattress is very comfortable for an air mattress. Switched from a 3 inch foam to this 4 inch foam and the extra inch helped so much with comfort. Very durable and seems to hold air so far. We've used it 3 or 4 times camping over the past few months and have had no issues. Comes with an air pump that works fast and is super lightweight. The mattress is really bulky when stored, but so worth it for the extra comfort the the foam provides.
