We received this tent as a Christmas gift. We love it!
Our family of 4 fits in here just right. We have a queen sized raised air mattress, plus 2 twin size floor air mattresses. We still have room for the bags and other items without anything touching the sides of the tent. The first time we set it up in our yard, we made sure to leave it up through a storm that came through. It poured on this tent and the water just beaded right off of it (obviously the rainfly was on, too). Checked it out afterwards and not a drop inside.
We did a week long camping trip to door county and there was another few rounds of rainstorms that came through, one night it was a crazy amount of rain and still nothing wet in the tent! I think one of the great features that allows it to be so waterproof is that the tarp-like material comes up about 6-8 inches all the way around the base of the tent.
The only drawback or con that we found - and maybe this is completely normal with new tents, but the set-up of this tent is pretty snug. We've tried it both ways, giving it slack, and making it taught, and it still was snug when setting it up. So much so, that the door can be a little hard to open, so just be careful with the zipper and watch your seams if that is the case.
Otherwise, enjoy a nice dry bed and floor with this great tent!
