Best cot mattress

Sleeping

A cot mattress isn’t just great for your cot. You can use one as a bed for guests, or turn it into a car-camping mattress for summer road trips.

Which cot mattresses are best? 

Cots aren’t always the most comfortable things. However, what your uncomfortable grandfather’s cot didn’t have was a cot mattress. If you put a mattress on your cot, you can take any camping experience from one of tossing and turning to one of restful sleep. If you want a little extra cushion when you sleep under the stars, check out the Therm-a-Rest MondoKing 3D Self-Inflating Mattress

What to know before you buy a cot mattress

Do you have a sleeping pad?

If you want to get the most out of your cot, try putting your sleeping pad on it and see how you like it. If that doesn’t do it for you, it’s time to consider upgrading to a mattress, especially if you like to use your cot in colder weather.

Do you have a built-in mattress already?

That may seem like a silly question, but some cots come with attached mattresses. Maybe that mattress isn’t very comfortable. There’s no reason to get rid of that one just yet though; consider putting your new mattress on top of the old one if you really want to maximize comfort.

What size is your cot?

The concern here mostly is width. Cots are generally the same length (although not all) but can vary in width. You may have a 20-inch single cot or a 35-inch double. Either way, make sure your mattress is as close to the width of your cot as possible. Too narrow and you miss out on usable space. Too wide and your mattress won’t fit well or stay on properly.

What to look for in a quality cot mattress

Thickness

Maybe you’ll be fine with an inch of memory foam that you’d find in a mattress topper. Maybe you want a 3-inch-plus mattress. Just make sure your mattress is thick enough for your preferences or your upgrade won’t seem like much of an improvement.

Foldable vs. rollable

Generally, you can get your mattress rolled or in a trifold. It may not make a difference for most people. However, if you have a certain space you want to store it in or are worried about putting it on your car’s floor, make sure you have the right style.

Weight

You probably aren’t lugging this into the woods. Most likely, it will just go from the car to the cot. However, if you plan to take it with you, make sure you don’t pack more weight than you absolutely have to.

How much you can expect to spend on a cot mattress

Just like the mattress on your bed, there’s a wide variety of prices. Depending on your preferences, you can pay $50-$400.

Cot mattress FAQ

Is a foldable mattress better than a rollable one?

A. This depends on your preference. A rollable one might be easier to lash to a backpack. A foldable one may have a smaller footprint but may not be as easy to carry. It comes down to what you want it to do. In general, just looking at the packed size dimensions will give you the answer you need.

Can you use an inflatable sleeping pad as a cot mattress?

A. Yes, you could. If you want something for your cot that can stand alone while backpacking, it’s a best-of-both-worlds option. That said, it’s likely an actual mattress will perform better for what you want when cot camping. If you’re set on a sleeping pad, a self-inflating one instead of a blow-up one is the way to go.
