We also carry out numerous field tests in real-life conditions.

Used for 1 week or less
We bought these for my husband and son as they were going on a camping trip. They both found them very uncomfortable to lay on. We did wish we had bought an inflatable mattress which is what we will be doing for future camping trips.

Response of the brand
Hello Mr Monty,

Thank you for taking your valuable time in sharing your experience with us. We are sorry to hear that the mattress size is not sufficient for you. This mattress is the lightest in our range designed for Trekking where you need to carry this for multiple days. I have provided links to the mattresses which are on the heavier side but much more wider.
