This popular, highly rated SoundaSleep Dream Series inflatable air mattress isn't cheap -- but it does what is a confined space mattresses are supposed to do. Priced at $120, the SoundAsleep air mattress is more expensive than most of the other models we tested in its height range, but it's durable and if you ask us, it's the overall best air mattress on the market. Though we take Amazon customer reviews with a grain of salt, this mattress has more than 11,000 five-star reviews testifying to its durability and comfort. (Fakespot, which grades the trustworthiness of Amazon testimonials, gives this bed's reviews an "A.")

SoundAsleep calls this a double high airbed, and it is on the taller side -- you're sleeping a good 18 inches off the ground. An air coil design helps this mattress to maintain its shape but like many inflatable bed models that come with an integrated electric pump, it's plenty heavy, weighing about 19 pounds. The pump is loud but powerful. It took a reasonable 3.5 minutes to fully inflate the mattress -- and I mean fully -- and about the same to deflate it.

The SoundAsleep Dream is made of rigid plastic that's still easy enough to fold up and stuff into the included nylon drawstring sack that serves as a carry bag, which is great for camping. But it's also one of the more pungent beds I tested, and people who are sensitive to off-gassing may want to choose an alternative.

When you order directly from SoundAsleep, there's a 30-day no-questions-asked return period. If you buy from Amazon or SoundAsleep, you get a limited one-year warranty that covers manufacturer's defects (but not punctures or holes made on your watch). You'll need to pay for shipping the mattress back to SoundAsleep.

The bottom line: This SoundAsleep Dream series mattress is not cheap, but it is worth the money. Inflates fully, well-constructed, strong customer reviews, slightly more pungent than others. Recommended. 

Intex has struck a compelling balance between price and value with the Comfort Plush Elevated Dura-Beam. Though it's on the cheaper side, the Intex Comfort Dura-Beam is sturdy, impressively firm, with horizontal air chambers -- and ultimately it's comfortable enough to sleep on.

The integrated, plug-in pump isn't as fast an inflater as others but it's plenty powerful and the bed ranks among the firmest blow-up mattresses that we tested. The top and sides of the mattress are coated in a velvety treatment that Intex says makes it more puncture resistant. That may be true, but it also means that if you do spring a leak, you'd better hope it's on the bottom panel, which is the only place a patch will stick.

The Intex Comfort Dura-Beam is also one of the tallest air mattresses we tested, measuring 22 inches high when fully inflated. There's a little lip around the periphery that suggests there's a protective barrier designed to keep you from rolling off (it won't). But the bed is quite stable. The movements of a person on one side shouldn't bother a companion. The mattress comes with a duffel bag for storage. And, compared to the others, I didn't find it particularly pungent.

The retail price for this mattress varies between $50 and $135. There are plenty of air mattress reviews for this model that mention leakiness but there are many more five-star customer reviews on the site than lower-rated ones. Still, Fakespot rates it a "C," which suggests that there may be some degree of "deception involved." Intex covers this air mattress with an exclusion-filled, 90-day warranty.

The bottom line: This is a reasonably priced, tall air mattress that's relatively comfortable to sleep on. Recommended.

Designed for camping, the Lightspeed Outdoors Air Bed Mattress lives up to its name: At six pounds, pump included, this temporary air mattress option is undeniably lightweight. This camping mattress comes with a storage bag and a compact, battery-operated pump, which takes four D cells (not included). Compared to a typical plug-in air pump, the Lightspeed bed comes up short. I let it run for more than six minutes but could never get this mattress as fully inflated as I wanted. (The "deflate" setting on the air pump is similarly inefficient. I'd recommend saving the batteries and rolling up the mattress to expel air manually.)

Lightspeed Outdoors emphasizes that this camping air mattress is Phthalate- and PVC-free, constructed instead out of Thermoplastic polyurethane which feels more durable and smells less plasticky than the material used for most other air mattresses. If you're sensitive to chemical smells or off-gassing, this mattress deserves special consideration.

This air mattress for camping measures 55x79 inches -- slightly smaller than the technical queen size dimensions of 60x80 inches -- but I didn't have any problem getting standard sheets to fit snugly. And though Lightspeed doesn't specify its weight capacity, I suspect it's more or less in line with the others I tested. My two kids and I (combined weight: roughly 320 pounds) assembled comfortably on it.

Note that I observed that the Amazon price for this mattress varied between $40 and $100 while I was working on this article, with some colors being more expensive than others.

The bottom line: Best suited to car camping, the lightweight and reasonably priced Lightspeed Outdoors air mattress is far cushier than a sleeping pad. It's noteworthy for its use of alternative materials and will make a good choice for those sensitive to the pungent off-gassing of many plastic air mattresses. 

According to REI, this is not an airbed -- it's a "sleep system." And, at $299 for the queen bed, an expensive one at that. But we found it worth the price if you're looking for a super-firm, durable mattress that comes with dedicated linens and a comforter.

The sleep system includes an insulated air mattress, a fitted sheet, a top sheet, a quilted comforter and, somewhat surprisingly, given the price, a hand pump. The mattress is sturdy and well-constructed. And using the included Bravo hand pump, I was able to inflate it until it was absolutely taut. Yes, it took about two and a half minutes of vigorous, aerobic pumping -- and that doesn't include multiple hands-on-knees timeouts -- to inflate it.

Still, the degree of firmness you can get from the Sleep System is distinctive from other mattresses. Most of the other air mattresses we tested, and especially those that came with a battery-powered pump, were impossible to fully inflate, making for a sleep experience that ran the gamut from slightly saggy to fully dispiriting. Though it requires hard work, REI's manual pump is by far the most powerful and effective one we tested. Deflating was quicker and easier, and the mattress itself -- separate from all of the included linens -- is relatively light and compact.

REI's bedding is bulky but nice. The fitted sheet includes elastic bands at the corners, to keep it in place, and the comforter and top sheet can be connected with the kind of toggle and loop you'd find on a tent fly. As a result, everything stays where it's supposed to. REI says that the sleep system's insulation (3.6 R-value) will keep you warm in temperatures down to about 40 degrees. That's more than adequate if you're sleeping inside a house or apartment, but I suspect cold weather campers would want additional blankets or a sleeping bag.

The bottom line: This is a very expensive air mattress -- but it's well-made, comfortable to sleep on and suitable for both indoor and camping use. The manual pump takes a lot of work to operate but gets the mattress firmer than any other we tested.

The epitome of a cheap air mattress, the $25 Bestway Airbed is compact, lightweight and relatively quick to inflate with its integrated pump.

On the downside, this air mattress model is not comfortable at all. It sits low to the ground at just nine inches high, and the pump isn't remotely powerful enough to inflate it fully, so it makes for a rather squishy ride. The tubular design gives it the look of a pack of hot dogs, and the one raised, horizontal hot dog that's meant to approximate a pillow rest, sets the mattress askew, which makes it even more unstable.

The Bestway Airbed has plenty of negative reviews on Walmart.com that cite slow air leaks, fast air leaks, burst seams, spontaneous bubbling and terrible customer service -- as well as dozens of very positive ones. And though Bestway's comically vague manufacturer's warranty doesn't instill confidence, given the price, warranty isn't a crucial consideration here. Still, Walmart's policy states that most products can be returned with their original packaging for a full refund within 90 days.

The bottom line: If you're looking for the least-expensive air mattress available, this is it. But unless you're a narcoleptic, don't expect to get a decent night's sleep on it.

The Beautyrest Hi Loft comes equipped with a plug-in electric pump that screws on to the body of the mattress. Once attached, it inflates the mattress quickly -- it takes about 2 minutes -- though not as fully as I would've liked. Once it's inflated, you need to quickly unscrew the pump and replace the valve cap. It's not the most elegant solution.

The Beautyrest has the same pack-of-hot-dogs design as the Bestway Airbed, and has the precarious feel of a pool float. (Many companies that make air mattresses also make pools and pool accessories. Go figure.) It lacks the stability of other air mattresses and I nearly tipped it over by laying too far to one side. Simmons lists its dimensions at 80 by 60 by 17 inches, but my measurements put it closer to 76 inches long, which means that anyone taller than 6 feet will likely hang off the end.

The mattress is constructed from a softer type of vinyl than others, which is easier to roll up and fold into a compact, storage-friendly shape.

The bottom line: Other inflatable air mattresses are more stable and more comfortable in the $60 range.

This air mattress retails for $110 but we bought it on sale for $80 from Target. I wouldn't recommend it at either price.  

That's not to say that the Serta 16-inch AirBed doesn't have anything going for it. The built-in electric pump is quieter than some of the other integrated electric ones we tested and its 8-foot power cord is longer than average, which might be an important consideration for some.

Still, even inflated to capacity, this air mattress is squishy, less supportive and more pungent than other mattresses we tested. And it deflated to a surprising degree during the 80 minutes that my kids laid on it while watching the movie Boy and the World, which doesn't bode well for a great night's sleep.

We bought our Serta air mattress from Target, which won't accept it for return once it's opened, but will exchange it for a new one within 90 days.

The bottom line: There are better and less expensive air mattresses than this one.

The King Koil Luxury Raised Air Mattress consistently ranks in the top 10 on Amazon's category bestseller list. But this may have as much to do with the company's mastery of search engine optimization and Amazon review gamesmanship as its ability to design a quality product. Fakespot currently gives this bed's customer reviews -- of which there are thousands -- a "C" grade for authenticity, which is better than the "F" it received previously.

Still, there are a few reasons to like the King Koil Luxury Raised Air Mattress: The built-in pump is powerful enough to completely inflate the mattress in just over three minutes and it's quite tall, measuring about 21 inches high.

But there are issues. Of the inflatable mattresses I tested, this raised airbed was the most pungent and plasticky-smelling inflatable airbed. This King Koil air mattress is also heavy. The queen-size King Koil air mattress weighs nearly 21 pounds, though Amazon lists it at 17. Even when fully inflated, this mattress squishes down significantly when you try to get up from it, and I found that it repeatedly lost considerable amounts of air overnight. For these cardinal sins, Consumer Reports has savaged the King Koil, singling it out as one to avoid -- and I concur.

The bottom line: Overpriced, odorous and less capable of remaining fully inflated overnight than others.

I'm not a fan of the Coleman AirBed Cot. It's expensive, heavy and unwieldy, hard to set up and, worst of all, uncomfortable to lay on.   

Coleman's air mattress isn't particularly distinctive in any way -- other than being one of the most pungently plastic-smelling I tested. To say that Coleman's included QuickPump, which takes four D batteries, is underpowered would be an understatement. The battery operated pump was unable to fill the air mattress to anything close to its capacity and I gave up after 10 increasingly frustrating minutes. (Some Amazon reviewers have resorted to using their mouths to inflate this mattress.) The pump nozzle doesn't fit snugly into the mattress valve and you're forced to hold it in place throughout the whole disheartening process.

But the steel backbone is something else: It makes the whole package absurdly heavy -- it weighs about 42 pounds, which is about twice as much as any other we tested, which makes it a poor choice for a camping cot -- though it comes with a wheeled, but ultimately unwieldy, carry bag.

The steel frame unfolds sort of like a pack and play -- that is, not easily -- and has no locking mechanism. But it does have a steel bar running down the middle -- which is a huge, body-wrecking bummer, especially when you're sleeping on a half-deflated air mattress. I suppose if two people are sleeping in this Coleman camping cot, each supine and occupying one of the trenches, as it were, it might work. But I wouldn't want to be either one of them.

There are a few thoughtful touches -- including a zippered pocket that holds the air mattress in place on the frame, and two foldable side tables, each of which has an integrated mesh pocket to hold a drink. But they're not nearly enough to salvage Coleman's Airbed Cot.

The bottom line: Hard pass.
