The 8 Best King-Size Air Mattresses In 2023
1. SoundAsleep Dream Series Air Mattress with ComfortCoil Technology — Best Overall
| Dimensions: | 82”L x 70”W x 18”H |
| Weight Capacity: | 500 pounds |
| Material: | Eco-friendly PVC, top flocking |
What are you looking for in a king-size air mattress? Is it firmness and stability? You’ll get plenty of that with the SoundAsleep Dream Series Air Mattress. This is thanks to the company’s trademark SureGrip and ComfortCoil technologies that eliminate the chance of sliding and slipping. That, in turn, ensures a good night’s sleep without disturbance. The mattress stays firm for long hours while the coils (48 in total) provide the necessary support for your body.
More good news: the SoundAsleep blow-up bed is well-protected against punctures and abrasions. This is a big pro for families with little children and playful pets. The air mattress is made of environmentally-friendly PVC and features a waterproof top flock. Add fast, friendly, and 100% free US-based customer support, and you’ll see why we named SoundAsleep the best overall king-size air mattress. You will have to give it 5–6 minutes to inflate, but that’s only a minor con.
- Firm and stable: no slipping/sliding
- Puncture- and abrasion-resistant
- Crafted from eco-friendly PVC
- Backed by free US-based support
- Takes up to six minutes to inflate
2. SLEEPLUX Durable Inflatable Air Mattress with Built-in Pump — Best Value
| Dimensions: | 80”L x 72”W x 22”H |
| Weight Capacity: | 330 pounds |
| Material: | Polyvinyl Chloride |
If this is your first time buying an air mattress and you don’t want to spend big bucks on it, SLEEPLUX might be precisely what you need. First, it’s a highly affordable airbed that carries great value. Second, it’s one of the thickest mattresses out there: 22 inches. That equals more comfort and lumbar support for you. The Ultra-Fresh coating also deserves our attention: it keeps mold, mildew, and bacteria at bay.
The Tough Guard material, in turn (polyvinyl chloride), aids in air pressure retention and protects the mattress from over-inflation. As a bonus, you’ll get a USB charger (built into the mattress), which is rather convenient. All in all, the SLEEPLUX Durable Inflatable Air Mattress is the best air mattress for the money. Its only downside is the weight capacity: 330 pounds (a bit low for a king-size airbed). Still, it’s worth every single penny.
- Available at an affordable price
- Extra thick mattress: 22 inches
- Features a built-in USB charger
- Antimicrobial coating
- Below-average weight limit
3. Ivation EZ-Bed (King) Air Mattress with Frame & Rolling Case — Premium Choice
| Dimensions: | 81”L x 73”W x 24”H |
| Weight Capacity: | 600 pounds |
| Material: | Polyurethane |
Are you a fan of camping? Then you already know how much pain it can be to find a proper spot for the mattress. That won’t be a problem with the Ivation EZ-Bed (King) Air Mattress! It’s got a built-in metal frame that only takes minutes to deploy. That’s right: all you have to do is push a button, and the steel construction will take care of the rest. More importantly, you won’t have to worry about dirt and debris damaging the airbed.
Another unique feature: the mattress collapses into a zip-up bag/case with wheels! Now, the auto-shutoff feature does malfunction sometimes. So, keep your eyes on it and switch it off manually, if necessary. Going back to the pros, this air mattress has 56 circular coils for a soft, comfortable surface and is backed by a 100% satisfaction guarantee. It’s not particularly cheap, though.
- Comes in a zip-up rolling case
- Self-deploying frame design
- 56 circular coils for a soft surface
- 100% satisfaction guaranteed
- A bit on the expensive side
4. EnerPlex Air Mattress with Built-in Pump
| Dimensions: | 80”L x 76”W x 18”H |
| Weight Capacity: | 800 pounds |
| Material: | Polyvinyl Chloride |
What sets the EnerPlex Air Mattress with Built-in Pump apart from all the other products on the list is the weight capacity. It can hold up to 800 pounds, which is quite impressive. You can have three big folks on it, plus kids jumping up and down, and the airbed will be able to handle that. We also want to mention the built-in pump. It only takes 1–2 minutes to fill the entire king-size mattress with air.
On top of that, it’s highly adjustable. You can fine-tune the pump to get the desired level of inflation/firmness. On the downside, the mattress gets pretty loud when it’s getting pumped up with air. Another minor con: when you unpack EnerPlex, it will have a plastic slash chemical odor. It will go away eventually, of course (in a day or two).
- Inflates in less than two minutes
- Adjustable pumping system
- Impressive weight capacity
- Plastic odor upon unpacking
- Gets loud when inflating
5. Intex Inflatable Fiber-Tech Elevated Comfort Airbed Mattress
| Dimensions: | 80”L x 72”W x 18”H |
| Weight Capacity: | 600 pounds |
| Material: | Polyester |
With Intex, you’ll get a thick (18 inches), durable air mattress with an above-average weight limit of 600 pounds. It’s crafted from polyester and doesn’t squeak or creak like most regular beds. Along with that, thanks to the indented sides, you won’t have to worry about the sheets “escaping” the mattress while you’re catching Zs. Next, the velvet top is incredibly soft and helps you get comfortable while getting ready to sleep.
The price tag on the Intex Inflatable Fiber-Tech Elevated Comfort Airbed Mattress is more than reasonable, though. Do keep in mind, however, that you might have to deal with some (minor) quality control issues. Some buyers complain about getting the wrong size. But customer support is quick to respond. Reach out to them, if necessary.
- Quiet, doesn’t creak or squeak
- Keeps the sheets in place
- Soft, plush velvet top
- Minor QA/QC issues
- Not exactly king-size
6. EZ INFLATE Double High Luxury Air Mattress
| Dimensions: | 80”L x 76”W x 16”H |
| Weight Capacity: | 600 pounds |
| Material: | Durable PVC |
Every single air mattress on today’s list is airtight and waterproof. But the EZ INFLATE Double High Luxury Air Mattress takes that to another level. Crafted from durable PVC, it takes water resistance to another level. And it comes with an incredibly soft and breathable top. Now, for most people, it might be a bit too soft and uncomfortable to sleep on; others will appreciate that. In any case, EZ takes a bit too long to expand.
While most mattresses stretch to their full size in 2–3 hours, this one needs a couple of days. That’s compensated by swift deliveries across the States.
- Crafted from 100% waterproof material
- Ultra-soft, breathable flocked top
- Fast delivery/shipment
- Might be too soft for you
- Needs time to stretch to size
7. Beautyrest Silver Lumbar Supreme Air Bed Mattress
| Dimensions: | 80”L x 75”W x 18”H |
| Weight Capacity: | 700 pounds |
| Material: | Vinyl and fabric |
Are you in the market for an air mattress with lumbar support? Then pay extra attention to the Beautyrest Silver Lumbar Supreme Air Bed Mattress. It has a three-zone support structure that keeps the spine aligned and supports it while you’re sleeping. You can adjust the three chambers individually to achieve the best firmness for your back. The airbed is well protected against stretching and air leaks as well.
The edge support system is another pro: it prevents you from “rolling off” the bed. Unfortunately, this also means you’ll constantly be rolling toward the center. That makes this air mattress a less-than-ideal choice for a couple. Beautyrest isn’t very strong against abrasion, either, so keep pets away from it. Lastly, depending on where you live, deliveries might take a while.
- Three-zone support technology
- Excellent edge support system
- Only intended for one-person use
- Not recommended around pets
- Slow deliveries within the US
8. RAPTAVIS King-Size Air Mattress Sofa Bed for Camping
| Dimensions: | 80”L x 72”W x 28”H |
| Weight Capacity: | 450 pounds |
| Material: | Polyvinyl Chloride |
If you’re tired of regular air mattresses and want something a bit different, you’ll get plenty of that with RAPTAVIS. Essentially, it’s a standard airbed, but with a set of pillows (inflatable) and a backrest. You’re free to adjust the backrest to your liking. The overall design does require some work, though: this isn’t the most comfortable air mattress out there.
Next, it tends to leak a bit, while the package doesn’t include a storage bag. That means transporting it in the back of the car could be a bit problematic. Still, the RAPTAVIS King-Size Air Mattress Sofa Bed for Camping is spacious, has a decent weight capacity (450 pounds), and will be a great choice for a camping adventure.
- Packs a pair of inflatable pillows
- Adjustable backrest included
- Doesn’t stay inflated for long
- No storage bag in the package
- Could be a bit more comfortable
Buyer’s Guide: How to Pick the Best King-Size Air Mattress
King-Size Air Mattress: How Big Is It?
Just like beds, mattresses come in different shapes and sizes. For example, the twin is the smallest size: 75”L x 38”W, best suited for children. Twin XL is a bit larger—80”L x 38”W—and is designed for taller folks. Full-size air mattresses are the golden middle between twins and twin XLs (75”L x 54”W). Queen airbeds are wider and longer, perfect for couples (60”L x 80”W). That’s why they are the most popular pick in the States.
As for king-size mattresses, they measure 80”L x 76”W but can be a bit bigger or smaller, depending on the manufacturer. These are the largest mattresses in the US, enough both for you and your significant other. Finally, we have the California king-size. It’s four inches longer than King. However, it’s also four inches narrower. Here’s a closer look at American manufacturing standards:
| Twin: | 75 x 38 inches |
| Twin XL: | 80 x 38 inches |
| Full: | 74 x 54 inches |
| Queen: | 80 x 60 inches |
| King: | 80 x 76 inches |
| California King: | 84 x 72 inches |
Are King-Size Air Beds Comfortable? Can They Hold Two People?
When it comes to mattresses, size does, indeed, matter: the more “room for maneuvers” you have, the more comfortable your shut-eye time will be. Now, king-size air beds are best-suited for couples (they easily accommodate two adults), children (3–4 kids), and pets. On average, king-size mattresses can hold 350–880 pounds which should be more than enough for two grown-ups plus a child or a dog/cat.
If you can’t sleep well when feeling cramped, king-size beds will be a great investment. Before you go buy it, make sure the mattress will fit on your floor, adjustable bed, box spring, or slatted base.
Air Mattress Thickness: Why Does It Matter?
Now that we have gone over the length and width, let’s talk about the thickness. As a rule, the thicker the mattress, the more comfortable you’ll be sleeping on it. High-profile airbeds begin at 12–14 inches, with the more advanced models reaching 16, 18, or even 20–22 inches. This way, there will be more layers and coils providing support for your back. Do keep in mind, though, that this also means extra weight to carry around.
Besides, when the mattress is too thick, that makes it harder to climb onto it. If you’re planning on buying an air mattress for your kid/teenager, do consider this.
Finding the Best King-Size Airbed: A Quick Guide
There are thousands of different offers on the market. How do you know which one to pick? Here’s what needs to be checked before buying an air mattress:
- Size and thickness. The longer, wider, and thicker the air mattress, the more enjoyable it will be. Also, when a thick air bed deflates a bit during the night, that won’t cause an inconvenience. King-size air mattresses have proven to be the perfect size for most people looking for comfort and back support.
- The material/cover. Most air mattresses are crafted from PVC, polyurethane, or vinyl. What you should check is whether the mattress is waterproof and puncture-resistant, or not. The number of coils matters as well. Generally, the more coils the mattress has, the softer and more ergonomic it will be. If there’s a top in the package, it should be soft and breathable.
- The pumping system. Blow-up beds can’t function without air. That’s why they come with a built-in pumping system. Some take longer to inflate than others, though. Look for adjustable pumps that allow setting the perfect firmness for the mattress. The best option is a dual pump: the first pump handles the inflating/deflating, while pump #2 maintains the pressure.
- Warranty and support. For air mattresses, a 1-year warranty is standard. But, with some brands, you can get a 10-year warranty. As for customer support, trust a company that provides long-term assistance after the purchase. And if you’re lucky, you’ll also get a convenient storage back, manual, and set of repair patches.
The Biggest Pros of Air Mattresses
What’s so special about air mattresses? Just how reliable, easy to use, and affordable are they? Here’s a quick look at the biggest pros:
- Reasonably durable. While this greatly depends on the material and the build quality, most air mattresses last for a long time. On average, expect them to last for 5–6 years. However, if you use the air bed every night, it will wear out a lot sooner (in 2–3 years). To increase its service life, invest in a water-and abrasion-resistant mattress. This is especially true if you have little kids and pets in the house.
- Very easy to fix. Even if the mattress does get punctured, fixing the hole won’t cost you much. The problem can be solved with some glue and a piece of plastic or vinyl tape put over the leaking area. Duct tape will work as well. Don’t forget to clean the damaged area first. Also, apply pressure to the patch, and give it 2–3 hours to set before test-driving the mattress.
- Provide support for the back. To get proper lumbar support on a regular bed, you’ll have to pay a pretty penny. With an air mattress, you’ll get the same treatment for a lot less. Not all blow-up beds are orthopedic, of course. But, if you’re ready to pay a bit extra, it won’t be hard to find one with the right coil beams that ensure a good night’s sleep.
- Affordable and highly accessible. Inflated mattresses today aren’t at all expensive. On average, you can get a decent-quality king-size air mattress for $100–150. For $200–300, you should expect even more comfort, better material quality, and some extras like a self-deploying frame, multiple zones, and more.
- Flexible, user-friendly design. One of the best features of air mattresses is the pump. With it, you can inflate or deflate the mattress in 2–5 minutes. On some advanced models, there’s the option of setting the desired inflation for extra comfort. This can be done with a single switch! Just plug the cord into a power outlet, and it will do the rest.
- Take little space when deflated. In contrast to full-fledged beds that are both heavy and large, airbeds get tiny when deflated. That means you can store them somewhere in the corner when not in use or put them in the back of the car on your next trip into the wilderness. And, since the pumps usually come built into the mattress, all you’ll need to “bring it back to life” is a power source.
The Biggest Cons of Air Mattresses
There aren’t that many disadvantages to air mattresses. For the most part, if you pick the right size, weight capacity, and feature set, it will be money well spent. Still, here are the most significant cons:
- Regular maintenance. No matter how expensive the mattress is, it needs to be inflated regularly. Sometimes, it might even deflate in the middle of the night, causing discomfort. Besides, while patching holes isn’t rocket science, it does take time. You won’t have any of these issues with a standard bed.
- Noisy and with an odor. As mentioned, most pumps aren’t exactly silent. And, while they take less than ten minutes to inflate the airbed, this is still a con. Another minor downside: when you unpack the air mattress, most likely, it will have a chemical smell. That odor might linger for a couple of days!
- Not for long-term use. If you’re only planning on using these mattresses once a week or so, that’s 100% ok. However, despite all the features like adjustable coils, triple zones, and such, inflatable mattresses aren’t always recommended as a full-time replacement for a bed. Using an air mattress might make matters worse if you have back problems.
- Poor temperature regulation. In contrast to foam mattresses with cooling gel, inflatable models can’t dissipate the heat. Since they’re mostly made from vinyl and various plastic types, you’ll find yourself sweating during nighttime. During winter days, you’ll feel cold instead. Putting sheets or a topper between you and the mattress might solve this.
