I rarely leave reviews, but felt compelled to share my experience here. I paid a few extra cents per foot to get this padding since I was installing carpet in my basement and I was worried about the possibility of a water heater leaking, a backed-up drain, or other various possible ways a basement can take on water. Turned out to be the best investment I've made in a long time. TWICE in the past few months I had major water events in my basement. First, a window well filled with water until the pressure on the window became so great it broke the glass, sending 50+ gallons of water onto my nice new carpet. The carpet was literally submerged in water. The remediation company sucked up the water, pulled the carpet and pad back, and set up carpet fans above and below the pad. Except for about 1/4 inch on the edge of the pad, the pad was completely dry on the inside, even though water flowed above and below the pad. For that, I just took a towel and squeezed the ends and it dried in seconds. Within 24 hours, the pad and carpet were dry, saving any risk of mold. I once had a normal pad that got wet, and it acted like a sponge...there was nothing I could do but throw it away. The remediation guy that came with the fans said there would have been no way to save the padding if it was normal padding, and that if they tried I'd probably have lost my carpet too. He said it is a wonder insurance companies don't require this for all new carpet installations that they insure. The second water event was caused by an overflowing toilet, and I just rented fans from Home depot and took care of it myself. The original padding laid right back down with no evidence there was a leak. I would never install any other padding in my house now. Only thing I would recommend, is that if you install it upstairs, you might consider having the seams taped when it is put down. This way, you prevent spills from getting under the pad. It will just sit on top of the pad and you can suck it up with a wet/dry vac and not worry about it getting into the subfloor. Hope this review saves someone else an insurance claim. Oh, and it is extremely comfortable.
