Eighth update, March 12, 2024 No change or refill since last update. Just fyi!

Seventh update, January 14, 2024 We added a 10-second shot of air about a week ago, as we both thought the mattress felt a little soft. It could just be that our preferences have changed. Or, either the plastic has stretched, or the tiniest of leaks has started. I'm not concerned yet. My strategy is to wait until a daily refill is needed, because a leak will be too small to find before then.

Sixth update, December 3, 2023 We have not added air to the mattress since the 4th update (below) in April. The bed was stripped down in November to the bare plastic and examined for bulges and deformations, with the intention to rotate the mattress for even wear. Although it looked and felt brand-new, it was rotated anyway as a precaution, as my partner is quite a bit heavier than me and also tends to teeter right on his edge of the mattress all night. One thing I have been meaning to add is the answer to a question that I have seen on some inflatable mattress discussions: Can I sit on the edge of the bed to get dressed? Yes. You could even do your physical therapy (like stretching by hanging your shoulder off the side) or exercises (like quadricep extensions) off the edge. Unless you keep your mattress underinflated (in which case it will pillow up around your hips just like a plastic pool raft), it is firm enough to sit on the edge to put on socks, and to support you as you push off it to stand up. Caveat: Our mattress sits on a bed frame that is high enough that my feet just touch the floor when sitting on the edge; if you put your mattress directly on the floor it will take more leverage to get up, just like with a solid mattress, and may not give you adequate assistance pushing off. If you have trouble getting out of bed due to bad knees or back, for example, I would suggest raising the mattress to sitting height or a little higher so you can slide right into a standing position.

Note: This mattress has not been routinely deflated and re-inflated. I only let some air out twice when my partner said that it was too hard for him. Then when the new plastic stretched we both agreed it need another small shot of air. In my years of experience with an Aerobed, pinhole leaks seemed to be associated with deflation and reinflation, which we used to do to make it easier to change sheets. I could be wrong about this association, but repair is more difficult than muscling sheets onto a fully-inflated mattress. To save myself the possible trouble of having to find and glue shut leaks, I therefore have simply left the mattress fully inflated the entire time that we have owned it.

Fifth update, September 10, 2023 Almost one year after purchase, this mattress is still not losing air and not losing shape or integrity. We sleep on it every night. For the summer months, we took off the insulating layers we added (eggcrate foam encased in vinyl allergy-proof cover and reusable mylar blanket). Those will be added again now that the weather is cooler. In the coldest months we'll add the electric blanket.

Fourth Update April 19, 2023. Six months later, still sleeping nightly on this mattress. No leaks. But the plastic may have stretched a little because we both decided it was feeling too soft. I gave it two 10-second shots of air from its pump. Since it doesn't have any mechanism to avoid overfilling, I add air conservatively, lying down on it to test firmness after each little shot of air. Original review plus updates below.

Third Update March 5, 2023. We're still sleeping on this mattress nightly. It's been almost 5 months.

Second Update January 17 2023 We have been sleeping nightly on this mattress for 3 months. Still comfortable and happy, still no leaks. I notice that the price has doubled since I bought this one: was $37, now $82. I would still recommend it at this price.

Update December 14 2022: It has now been 2 months since we bought the mattress. The two of us sleep on it every night. Together we exceed the stated 300-lb weight limit (total 360?). Not a single leak, never have had to top off the mattress after its initial breaking-in period of a couple of days. Buy this mattress. If you get one that needs to be refilled in the morning, SEND IT BACK for a replacement--that's a defect, it is not normal! Original review follows. Love, Carolyn

This mattress is perfect. I breathe a sigh of delighted relief and gratitude each night as I get into bed. If you are looking for a substitute for the classic Aerobed, this is your best bet.

We've preferred air mattresses for many years. At first it was because we were moving around a lot and were sick of hauling conventional mattresses and box springs with us. Then it was because we built a platform bed and needed something that was easy to lift and get into position in the frame and that wouldn't add to our own weight on that frame. And then I realized that it was simply the best mattress that I'd ever used. We slept every night on that Aerobed for TEN YEARS, occasionally patching tiny holes. But it was a standard size and we eventually decided to get a queen, so we saved the standard for guests. And that's when the trouble started.

In less than 4 years, we went through 3 mattresses of different brands because we could no longer find Aerobeds in queen size. We tried the Sound Asleep Dream Series because it was reviewed as the most durable bed, but it failed catastrophically in less than a year, developing a rip overnight that was too big to patch. We then tried the Englander Double High, which again was reputed to be super durable because of the unusual materials. The Englander warned that you had to let the mattress stretch for a few days, refilling it each morning. So we did that, but eventually it became clear that it simply had a slow leak right out of the box, a leak so slow that we weren't able to find it to try to patch it. We spent a miserable year sinking into the mattress over night, using the unspeakably loud pump to refill it just before bed, then doing it all over again the next day. It eventually developed an enormous hump from one side to the other, and that was the end of that. We gave it to a family to use for their small children on either side of the hump.

Then we tried a memory-foam-topped conventional mattress, the heat and discomfort of which we endured for 2 months before realizing that we were never going to get a good night's sleep again if we kept giving it another chance.

So then I did a long, long, long search, and decided to take a chance on this Ener-Plex Never Leak. Reviewers here seemed to like it, though no one said that they were sleeping on it for years at a time. And it was $35, so no huge loss if it sprang a leak. It's now been a month and a half. Not only has it never leaked AT ALL, but it only stretched after the first night. After it was topped, it never needed anything.

It's stable, so my partner and I don't wake each other when we move. Yet it has the resilient bounciness that we so love. It can be adjusted to the firmness that the sleeper prefers. We like the bed to be nice and tight so we keep it full.

Don't worry that it is thinner (only 9 inches tall) than many of these newer styles. The extra thickness doesn't add any comfort, and it tends to make the bed less stable such that it can sway from side to side. I'm now also convinced that the thicker the mattress, the more vulnerable it is to the internal supports breaking and/or the places where those supports attach to the surface to tear. This happened with all three of our taller mattresses. Our old beloved Aerobed standard was also only 9 inches. Coincidence? I don't think so. Go ahead and get the thin one, I promise it's quite thick enough and your elbow and knee won't hit the floor.

At this point I'm convinced that we'll be able to sleep every night on this mattress for at least a year before it springs a leak. I'm not too worried, though. I think this mattress is basically the old Aerobed, and it was at least 4 years before that one got its first pinhole in it. I patched pinholes with a few layers of aquarium-type silicone sealant.

Caveat: If you are thinking of making an air mattress your permanent or long-term bed, you must be prepared for a couple of things. They are COLD COLD COLD, and your own body heat can never warm them up. In the summer, this is great, because the bed will suck the heat out of you for a comfy night's sleep. In the winter, it is awful, because it sucks the heat out of you for a miserable night's sleep! Therefore, you need some layers on top of it. I recommend a sheet of conventional egg crate foam, with a low-voltage electric blanket that will stay on for at least 10 hours or however long you need to sleep. Turn on the blanket while you are getting ready for bed.

I highly recommend this mattress. Since they are both cheap and small when deflated, we may buy 1 or 2 more as backups, to avoid the sadness we experienced when the Aerobed was discontinued.

We use this for sleepovers and is excellent twin size mattress extremely easy to blow up with the included air pump and very comfortable. Also like the material and I would definitely recommend it.

We got this to replace a fifteen-year-old Aero mattress that finally sprang a leak. I think the Aero company made the best air mattresses ever (does anyone know what happened to them?), so I'm holding this Enerplex to a high standard. And it holds up pretty well. I'm halfway through a cross-country road trip with my grown sons, camping for the most part, and this air mattress has done what we've needed, without any hassle.
Pros:
--Thoughtful design: The mattress comes packaged with a good nylon stuff sack with a pair of shoulder straps, so you can backpack it if you need to (although I can't really imagine why you would, but that's just me). In the stuff sack, it folds flat to a package about 20" x 15" and maybe three inches thick, flat enough to fit among your gear without trouble. It includes a powered air pump with a selection of nozzles (so you can also blow up your pool floats, or whatever), with a suction port if you need to deflate something quickly. Also included: 120v and 12v power supplies/cords, so you can run the pump if you're camping at a place w/o an electric hookup, and a small stuff sack to keep all the pump parts together. The pump and other bits in their sack don't add appreciably to the profile of the folded air mattress in its stuff sack, but having a separate sack for the pump also allows you to tuck the pump in separately if space is at a premium.
--It's comfortable: the top surface is flocked, so you and your sleeping back don't slip off. Properly inflated, it has the usual tube-and-air-channel construction, so it provides good support.
--Easy to use: Inflating is easy enough to do in bad light when you're tired. Just plug it in, and press-fit the nozzle of the pump to the inflation port. The port has a one-way valve, so you don't have to rush to close the valve when you're done inflating; closure is a simple screw-on cap, secured to the valve with a short leash. I haven't managed to cross-thread it yet. No significant leakage yet. Deflating requires you push the one-way valve open by pushing it back with your finger until it catches inside the valve ring, easier to do than describe. If you don't have time to let it deflate on its own, you can reverse the pump to speed the process. The two power cords (120v and 12v) are maybe six feet long each. The length of the120v cord isn't an issue, because you can always plug it into an extension cord, but the 12v cord doesn't really reach far enough from the car to allow you to inflate the mattress anywhere but inside the car--which may be possible if you aren't travelling fully loaded; otherwise, you need a second person to hold the mattress off the ground as it inflates.
--Durability: still an unknown. The vinyl feels slightly less robust than my old Aero, but I don't know if that's anything to go on. It doesn't feel flimsy by any means. It has held up well over several weeks of daily packing/unpacking & inflating/deflating. We're currently hunkered down in a cabin, where we're keeping it inflated, and it went a week before needing to be topped off. So far, so good.
Cons: chiefly the short 12v cord or the absence of a rechargeable battery. Aero was able to fit a good battery inside a reasonably sized pump housing 20 years ago. I assume the lack of one in this pump is to keep the price low, and in the current inflationary climate (OK, no pun intended bc it's not funny) it's the kind of sacrifice we have to get used to. But I don't think it would have added much to the price to put a good long (20') cord on the 12v power supply, so you could inflate the mattress inside the tent, or somewhere else where it would be safe from damage.
Summary: good value for the price, an entirely satisfactory air mattress for car camping (or the occasional guest).

I almost canceled my order for this after reading a bunch of bad reviews. I am very glad I did not! This air mattress was perfect for what I needed. It inflated easily. I did not have to refill it for the three days that I used it. It was comfortable. It was quiet. its very large! It came with a convenient backpack holder to fold everything up and bring it home. Loved this mattress, great value for the price.

Did not deflate at all through out the entire night. Comfortable. Easy to use. A+ recommend.

I purchased the Never-Leak Camping Series Twin/Queen Camping Airbed to use as a mattress on my daughter's top bunk bed, and it has been a game changer! We've been using it since December, and it’s now nearly June without a single leak.

My 7-year-old daughter finds it incredibly comfortable and has not complained once. As a parent, the ease of changing sheets on this airbed is a huge plus—it’s so much simpler compared to a traditional mattress. The durability is impressive, given that it has maintained its integrity over several months of daily use.

If you're looking for a versatile, reliable, and comfortable airbed, whether for camping or home use, I highly recommend the Never-Leak Camping Series. It’s exceeded our expectations in every way!

This was very comfortable and inflated really easy. Top has some type of fabric which feels annoying so it must be covered. All in all its a great air mattress.

---

I have used this mattress every night since December 2022, and I am ordering another one, very pleased with it. I have used 3 other brands and none lasted longer than 6 months.

Had an issue where the pumps were not included in the boxes (I ordered 2). Reached out to seller and it was resolved immediately. Thank you, I am grateful. As for the mattress itself, I blew air in it using my bike pump and it held the air. Comfortable mattress.

It sounds a lot while you're sleeping, not satisfied that much.
