Features

  • Superior Support and ComfortThis Sleeping Pad boasts a 4.5-inch thickness and 8.5-pound foam filling, delivering unparalleled support and comfort. With a weight capacity of up to 300 pounds, this sleeping pad accommodates a variety of body types. Its unique internal structure ensures even distribution of air and foam throughout the pad, effectively reducing pressure points and providing a good night's sleep. Please note that this pad is not recommended for backpacking.
  • Adjustable SoftnessThis mattress utilizes a unique combination of foam and air, making it fully adjustable for personalized softness and support. This means you can easily adjust the pad's comfort to your liking, allowing for the best sleeping experience. Compared to single-material sponge or memory foam pads, this sleeping pad offers a higher level of personalization and comfort.
  • Silent and Stable Support for Quality SleepThe mattress provides a stable sleeping surface with minimal noise, ensuring that your movements won't disturb your sleep or your partner's. Unlike other air mattresses that may make annoying squeaking or rubbing sounds, this unique combination of air and foam construction keeps you comfortable and quiet throughout the night.
  • Easy Inflation and Challenging DeflationThe mattress is incredibly easy to inflate, just twist the valve, and you're good to go. However, because of its bulk and weight, deflating the pad may take some patience. To solve this problem, we offer an electric pump, which you can purchase separately. The pump can be used for both inflation and deflation, making the process quick and convenient. Please note that stowing the pad may take some time and effort, but the comfort it provides is worth it.
  • Four-Season InsulationThis sleeping pad boasts an R-value of 13, offering exceptional insulation in cold environments and surpassing many other sleeping pads on the market. The 8.5-pound foam filling ensures comfort and appropriate insulation in various outdoor environments.

  • Great for humans and dogs, not cats Great for humans and dogs, not cats
Color: Brown Size: Single Style: Mattress Only
I bought 2 of these (well 3, but that’s a later story) for a glamping trip. I hate air mattresses with a passion, but like to have a higher bed, and my husband convinced me to get these despite me thinking I wanted to do it cheaper. I am so glad I did! We put them on our single cots side by side and had the best nights sleep. Which, btw couples, this is the way to go so you can be close but not disturbed if one person moves a lot throughout the night. I didn’t love the manual inflating or deflating process but with a pump I’m sure it’s great. With this setup there was no freezing-yet sweating feeling like traditional air mattresses because of the foam. We thought it deflated a bit the first night but I think it was just because it was cold, because the pressure didn’t budge at alol after adding more air the second night. I’m a side and stomach sleeper and usually have a lot pain in my hip, but this was SO COMFY! This was in my top 3 glamping purchases recently. My dog really liked it, too. So, if you’re still reading- the reason I bought 3 is because my kitten decided to bite through one of them before I even before I even took it out of its wrapping. He’s such a jerk! I emailed customer support to see if it was salvageable and they suggested I get some of the patches they sell specifically for this. I did and it seems to be holding steady. I did not take that one on this trip because the patches arrived too late, but if it holds I’m not mad about having this for guests. Adding a pic of the art and the artist for your enjoyment and his shaming. ... show more

  • Super comfy, high value for the money.
Color: Brown Size: Single Style: Mattress Only
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. ... show more

  • So comfortable for camping/glamping!
Color: Brown Size: Single Style: Mattress Only
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! ... show more

  • Excellent Mattress But You NEED an Air Pump
Color: Brown Size: Twin Style: Mattress Only
I finally broke down and bought a foam camping mattress. I took it on a 3 night camping trip where it rained nearly 100% of the time and this did very well. I don't sleep well on normal air mattresses and decided I needed to change and I'm glad I did. Pros: - Sleep very comfortable - Kept me warm in nearly freezing temps - Self inflates but does need a tad bit more air. However, it worked well with no additional air. Cons: - Won't stay inflated, this is due to the valve type it uses. It doesn't seat correctly and bleeds air around the ring if not centered correctly - A royal pain to try to get the air out and rolled up if you don't deflate it first. You need a pump that has enough power to overcome the foam pressure. Mine does not. - Does not use a standard pump fitting size. I was sort of able to make it work with my pump but was too weak anyway but did eventually evacuate enough air. IMO, so far, the Pros far outway the cons and I think this type of air/foam mattress will have these types of complications anyway. For the price I paid I think it's great. ... show more

  • Amazing product!
This is an amazing purchase. Bought this for Camping. Unlike a typical air mattress that has no support. Or on cold nights and it deflates a bit, your spouse gets out of bed and you fall to the bottom, just to get launched when they get back into bed. This firm, comfortable and very supportive. When my spouse gets in and out of bed, I dont even feel movement in the mattress. These air & foam mattresses are more expensive. But by far worth the extra price. I will never buy another air mattress again. Only, air/foam mattresses for me, from now on. ... show more

  • Two 75x25 inch ones, placed side by side, fit perfectly in the Sienna.
Color: Brown Size: Cot Style: Mattress Only
I purchased two 75×25-inch mats; they fit perfectly side-by-side inside my Sienna. At home, inflating and deflating them manually on the floor was very convenient—perhaps because their compact size meant I didn't have to fold them. I do own an air pump, but using it didn't seem much faster than doing it by hand. So far, the comfort level feels excellent. I'm looking forward to putting them to the test during my camping trip to Moab early next month, and I hope the product proves to be durable. ... show more

  • Very comfortable.
Color: Brown Size: Twin Style: Mattress Only
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. ... show more

  • Just what I wanted, but kind of wish I had gotten the double now.
Color: Brown Size: Single Style: Mattress Only
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. Almost 3 years later lots of camping with these. One no longer holds air. Dish soap spray test revealed it’s the entire cloth part no fixing it. The other one is still working. I am changing to 4 stars. Nothing lasts forever but why did it have a massive failure and not sure you can do anything to fix it ... show more
