Therm-A-Rest MondoKing 3D is a self-inflating foam camping mattress that is perfect for luxurious relaxation in the middle of your adventures. This has a thick and comfortable texture with a large size to accommodate you without any concerns or adjustments. It is built with a twin lock valve for easy inflation and deflation during set-up.  

Size:

Dimensions: 72” x 25” 2.5”

Weight: 1lb 4oz

Material: Nylon. Polyurethane

R-Value: 6.9

Verdict

Therm-A-Rest MondoKing 3D has a wide range of uses. You can utilize it during your camping and any outdoor activities. The comfort it can provide is definitely luxurious because of its thick and breathable surface.  

What we like are the dual valves which make the set-up and take down a lot easier. The “in” and “out” twin lock can assure the air you inflate and deflate. This is also a warm mattress because it has an R-value of 7 however we noticed that this is a bulky and heavy material if you are going to carry it alone. The unfolded measurement is already big and that goes with its packed size which we suggest you transport it with a car. 

On the other hand, the whole feature of MondoKing is commendable although this is expensive, you can enjoy the advantages you can get with this equipment.  

Comfort and Warmth

This inflatable camping mattress is definitely must-have equipment if you are seeking for relaxation on your camping adventures. As you can visualize on the photos of Therm-A-Rest MondoKing 3D, the bed defines comfort and assurance on your sleeping or resting positions.

Based on the manufacturer's description, this air mattress is self-inflating for portable backpacking if you are going somewhere. Though this can be set-up with air, it has a 4 inches loft to stabilize the comfort anywhere you place it. 

The thickness of MondoKing can be seen when you fully inflate it. The mattress will be transformed into a bigger and more beefy physical feature. It's not just thick, it is also wide that you won't be worried about your size since it can accommodate you with more than enough space.  

In connection, as the mattress is self-inflated type, the manufacturer designed dual valves for the air access and exit. With this system, a person can adjust the size easily because most inflatable types of equipment have only one entrée for the air outlet. This feature is also an advantage for an easy take-down and set-up which we will discuss later on the next topics. 

Since the size is of the mattress is thick, you can partner it with another mattress to expand the bed's size. In this way, you can rest together with your companion or partner with connected air beds. 

However, we recommend you add more air before you lay down at night because the valve can easily release air which may deflate your mattress while you are sleeping. 

The material used in this inflatable mattress is really comfortable and breathable. We recommend this item based on our experience during our previous outing.  

MondoKing has a 7 R-value. R-value is the measurement of the capability of a sleeping pad to withstand heat. Higher R-value is equaled to higher insulation to cold temperature. The value of this mattress does not totally mean that it is very hot that your sweat will drip. What we would like to suggest is that you need to check the weather at the place you are going to. 

Versatility

MondoKing can be used in different types of activities, may it be for camping or any outdoor adventure you are planning however, if we talk about the easy to carry aspects of this inflatable mattress, we can say that it is not suitable to carry around for walking or hiking.   

From our observation when we tested it, the weight of this mattress alone is 5.5 pounds. So if you are carrying your other belongings, it will be heavier just because of the bed alone. We suggest you transport it with a vehicleIf you are going to camp, you should see the area capacity of your tent to know if this bed can be used inside. 

Weight and Packed Size

We have discussed on the versatility section that this inflatable mattress is considerably heavy that you will need a vehicle to transport it however this is not complete bulky equipment if you are going to put it in your car. 

The large size of MondoKing has a measurement of 77 inches length, 25 inches width, and 4 inches height when you unfold it. The rolled size is 7 inches long and 26 inches wide but the packed size is 10.3 x 26 inches. The size is not a struggle and will not be eating up huge space in your car. 

We have carried this around with our vehicle and we can express that you can spare more spaces for your other bags or gears. This will still be dependent on how you pack your things. 

 

Ease of Use 

Let's discuss the level of difficulty when you use this bed. We mentioned earlier that this air mattress is made of dual valves. Not what is these dual valves? This works as the entrance and exit of the air, one for the inflation which is labeled as “IN” and “OUT” for deflation. 

These valves can found at the bottom corners of the mattress. This is also improved by the manufacturer for enhanced performance of the air suction. It is very convenient to use because the valves have different functions compared to other inflatable beds which have only one access for air. 

What we also like about the set-up is the fact that you can just blow in the air with your mouth. You will feel it can double the air suction inside because of the thick material inside that works as an inflation sack. Since this is a self-inflated mattress, we tried to let it fill some air alone which takes around 20 minutes but if you use a pump, it can reach up less than 3 minutes. 

Durability

The manufacturer has designed this inflatable mattress with different combinations of materials. As we have evaluated this equipment, we can say that it is a considerably sturdy type of air bed however, always take note that the life of these outdoor things will still depend on how you take care and use it. 

The top part of the mattress is made of 50D polyester and 75D polyester underneath the bed. This material is one of the commonly used types of fabric used on a variety of equipment or even apparel. It can resist wrinkling and stretches especially if you are using it for a long period of time. 

Pros

You can have these advantages with MondoKing:

  • Warm
  • Breathable
  • Comfortable surface
  • Easy to use 

Cons 

Be aware that this air bed is:

  • Heavy
  • Not suitable for carrying around
  • Expensive

Conclusion

So far, we can conclude that Therm-A-Rest MondoKing 3D is one of the self-inflating foam camping mattresses you need to watch out for. From the size it can accommodate to the easy way to use it, you won't regret getting one unit of this equipment to complement your outdoor activities together with your friends and family. 

If we compare it to other beds we tested, this is better and an advantage for your comfort and relaxation. Even though this is an expensive bed, the features you can get is reasonable for its price. The only thing you need to bear in mind is the weight but overall, this is a potential mattress.
