The must-have accessory this summer is an inflatable pool

For childless adults looking to entertain themselves and other adult friends, this is the pool you want. It's a 10-foot rectangular inflatable pool that can hold a few grown-up humans (though, children can obviously also fit).

With three air chambers, you'll get a nice, even inflation that doesn't take too long. And the pool is just shy of 2 feet tall, giving kids plenty of room to play and adults ample depth to soak.

When you're ready to dump the water, just pull the drain plug on the bottom of the pool to release it out easily.

Blow up pools aren't really for swimming — unless you're a small child who's shorter than the length of the pool. Most of us, though, are using these outdoor companions to cool off and relax.

This particular pool is top dog for chillin' out. Its two shorter sides have headrests, so you and another person can soak up some cool water and lay your heads back. There are also cupholders on the other sides for a truly chill experience.

The pool's thick lining is designed to act as insulation and maintain your desired water temperature. We're not sure how scientific it actually is, but could be worth trying out.

Another lounger, this pool takes it a step further with a full-on bench inside. You can sit and lean back while your kids play in the deeper part of the pool. The bench is also nice for really little kids who aren't quite ready to get all the way in the water.

This pool has five air chambers to inflate, but it blows up pretty quickly and easily. It's made from a thick PVC material for durability, and two drain plugs make for easy cleanup when you want the water out.

Check out the photos posted by reviewers to get a good idea for the size of this thing. It's pretty decently large without taking up too much space.

This pool is best suited for kids and smaller adults — definitely not big enough for a couple of adult friends to hang out in. It truly is a kiddie pool.

This inflatable pool fits well in small spaces, which is great if you're limited to a small backyard or patio. A lot of reviewers also used the pool as a ball pit instead of filling it with water, making it great for indoor play as well as outdoor.

This is a really affordable option if you just want a small pool to cool off in during the summer heat. It also comes with a repair patch in case you get any tears or holes.

The whole fam can soak it up in this rectangular inflatable pool. It has three separate air compartments that each blow up in about a minute if you're using an electric pump. This design is intended to prevent water and air leaks.

The design also allows you to create a shorter pool by opting to not inflate all three chambers. This is nice if you have really little kids who might struggle to get in and out of tall siding.

This pool features a drainpipe to make emptying the water easier. If you happen to get a rip or tear in the pool lining, don't sweat it too much — a patch repair kit comes included.

With a cute and trendy design, this banana leaf-adorned blow up pool is perfect for your backyard and your Instagram feed. It has "kiddie pool" in the name, but it's marketed as an "adult kiddie pool" for people ages 6 and up.

This pool is easy to inflate with a standard air pump. Or you can break out a hair dryer and set it to cool if you don't have an air pump, as the pool doesn't come with one.

Up to three people can comfortably fit in this mini pool. It features a drain plug in the floor, so you don't have to flip the pool over to empty out the water.
