Whether you have overnight guests, your kids want to have a sleepover with their friends, or you've just moved into a new place and are waiting for your furniture to arrive, an air mattress can come in handy. The best air mattress is comfortable, easy to inflate and super-convenient because it provides you with the extra sleeping space you need in a pinch. Plus, when you aren't using it, you can easily store it away in a closet.

Air mattresses aren't just good for indoor use, though: They are amazing for traveling, too. If you plan to go camping and don't have one as part of your camping gear, or if you're embarking on a road trip soon, make sure you have an air mattress for your trip.

But as with buying a mattress of any sort, selecting the best air mattress can be challenging. After all, you don't want one that spontaneously deflates in the middle of the night. Our carefully curated list has all the best options, whether you're looking for an outdoor or indoor air mattress, a non-toxic mattress or the best mattress for a specific kind of sleeper.

When you're shopping, make sure to consider these key features:

If you’re searching for the best mattress to have on hand for guests, look no further than the SoundAsleep Dream Series Air Mattress. This bed in a box, which comes in twin, twin XL, full, queen and king, is a host’s dream, going from flat to fully inflated—a “double height” of 19 inches—in just three minutes, thanks to its built-in pump.

It’s got a nearly 4.5-star average rating from over 47,000 reviews on Amazon because it checks all the boxes. Our Digital Deputy Editor tested this mattress and said that even her 200-pound husband was comfortable sleeping on it, and that it kept its shape and firmness through the night. It also deflates quickly and packs up easily for storage, which is key when you’re entertaining.

One of the best tips for overnights guests is, no surprise, to have a comfortable place for them to lay their head at night. If you're looking for an inflatable bed you can pull out at moment's notice, this is the best air mattress for everyday use to purchase. The Beautyrest Hi-Loft mattress has a velveteen sleep surface so your best bed sheets will stay in place.

And because it has vertical beam construction, it's able to hold up to 700 pounds, so multiple people can use it with no problems for days at a time. The air mattress also comes with a nylon carrying bag to store it away in, and an electric pump for quick inflation times.

If you're tall, you know that finding an inflatable bed that fits your height can be difficult and make it hard to sleep on vacay. Travel sleep tip that's just as important as finding the right travel pillow? Pick the best air mattress for extra length. Not only is King Koil's air mattress lengthy (it comes in a California King size), it has flocked material to prevent slipping, coils for comfort and a built-in pump that inflates it in two and a half minutes.

With over 6,000 reviews and a 4.4-star rating on Amazon, this Intex inflatable bed easily takes the title of most affordable air mattress. It cost just below $35 for a twin (up to just $39 for a queen) and includes a velvet-soft sleeping surface. It's also great because it has Fiber-Tech inner construction for support throughout the night, and a built-in pillow rest so you don't fall off the end. All you need is an outlet to inflate it with its high-powered internal electric pump.

This mattress from Lazery Sleep proves that sleeping on an air mattress can be comfortable! While it's on the pricey side, it's worth it because it's 19 inches thick and has a built-in air pump, flocked top, and remote to choose between seven difference firmness levels ranging from soft plush to extra firm. Its pump even shuts off automatically so you never have to be afraid about accidentally over-inflating it. Add some cooling bed sheets, and you'll be all set.

Sleeping on an air mattress that's always sagging is the worst. However, you won't have that experience with this 18-inch inflatable bed from Insta-Bed because it has a two-pump system to prevent sagging. The first pump has an automatic shut-off and is used to inflate and deflate it, while the second pump is quiet and stays on throughout the night, automatically adjusting the air pressure if it senses any drop in mattress pressure. The flocking finish makes it feel even more bed-like. Pair it with the best pillows and you're off to dreamland.

Believe it or not, air mattresses can come with built-in-frames to improve comfort. So how does it work? The Ivation EZ-Bed air mattress automatically unfolds while the bed is inflating with its built-in pump (which takes less than four minutes), so no tools are required. If you're searching for the best air mattress for older guests or a good mattress for back pain sufferers, you'll appreciate that this one is elevated 24 inches off the ground to emulate a real bed and make getting on and off much easier.

Want to sleep under the stars without being on the ground? If so, you'll need a SUV air mattress to go in your car. This one adjusts to fit in the back space of your vehicle and, with cold resistance down to -25 degrees, will keep you warm if the temperature drops at night. It also features independent air chambers and breathable flocking fabric for added comfort.

Younger children need a safe, secure and kid-sized air mattress when traveling. That's why we recommend this convenient toddler travel bed the next time you hit the road. It has a compact air pump included, and inflatable bumpers for safety not just on the sides but the head and foot as well (so active sleepers won't roll off). Plus, the inner mattress, which you can tuck your child's favorite sheets around, comes out for easy mattress cleaning.

Looking for a great gift for travel lovers? This backseat air mattress provides an alternative to tailgate sleeping. It fits in the majority of vehicles to use up all the space in the backseat for a cozy and comfy sleeping spot, and includes two inflatable pillows, a pump and a storage bag.

You'll be able to set up the sleeping arrangements in your tent in record time with this amazingly fast inflatable EnerPlex air mattress. The twin size takes under two minutes to inflate and has an easy-to-use, built-in pump—just turn the dial to inflate. You'll also be able to stay dry from any moisture on the ground thanks to its waterproof PVC material and Never Leak Technology, which is puncture resistant. Plus, because it has soil-beam technology, you won't ever feel like you're sleeping on the ground. Find yourself a free camping spot and enjoy!

This durable, indoor/outdoor bed from Coleman is the best air mattress for camping, ideal for a couple or family who wants to see the most scenic campsites in every state. With two twin-size air mattresses that can be attached side by side to create a king size bed or stacked for additional comfort, it's a versatile choice. And even though it's large, putting it away is easy thanks to its wrap 'n' roll storage system that enables you to roll the mattresses into the attached bag once they're fully deflated. Just make sure you purchase a pump because this one doesn't come with it.

If your dream camping situation does not include you directly sleeping on the ground, consider a camping cot air mattress. This one comes in both twin and queen sizes and has a battery powered pump and sewn-on cover, so you'll feel like you're sleeping in your regular bed while you're stargazing at night. The best part? It also includes a removable side table. A perfect gift for the camper in your life (or yourself)!

When it comes to hiking, a sleeping pad is almost as important as having a quality backpack. With a design that alternates between thermal foam and air, this insulated Therm-a-Rest air mattress will keep you toasty even during chilly camping nights. It also comes with a pump sack that makes inflating quick and easy—and since the regular size only weighs 15 ounces, it won't be much added weight to carry around.
