Thermarest MondoKing 3D

The Thermarest MondoKing 3D is a first for Thermarest with the use of sidewalls in a mattress. This gives the major advantage of increasing the useable sleep surface by 20% as you can now lie all the way to the edge of the mattress without it collapsing and you rolling off onto the floor. It also makes using it with another 3D mattress to create a double bed much easier as they can now be put directly side by side.

The foam core means that it is a self inflating mat so there's no need for pumps and batteries, just unroll it, open both the valves (there are 2 to increase the inflation speed) and leave it to do its thing, it will then require a few breaths to get it to the desired firmness. It also comes with a stuff sac with a carry handle.

Unsure if this is the right mat for you? Please read How to Choose a Sleeping Mat.

Reviewer: Jan, Somerset UK  

I bought this product because I am 63 years old and take Cub Scouts camping. While younger leaders got up in the mornings complaining of back ache from the hard ground, and how they were frozen all night, I couldn't wait for bedtime. I've never been so warm and comfortable in 30 years of Cub Camps. The mattress was as comfy as my own bed at home; I loved it. It's exactly as it says in the guidance and is not suitable to carry on hikes due to the bulk and weight, but if you're in one camp this is definitely the ultimate luxury. I used a 4 seasons sleeping bag with it because I need a coat at 60 degrees; I feel the cold so much. Can't wait for our next camp.
