Great comfort, not secured though
This is a great idea on paper. It provides a softer and warmer feeling underfoot.
The only problem is that the carpet doesn't stay in position. It lacks at least Velcro fasteners in the corners to hold it in place.
I've only used this carpet once so far and nearly fell over when stepping into the tent as the carpet slid on the tent floor.
Also, I shudder to think how to wash it after it gets muddy. By hand, I expect..
Other than that, a great addition to the tent.
