Firm, supportive, quiet and comfortable
We installed this in 3 bedrooms and a hallway in May 2021. I took a chance on this being a new product. I've been happy so far. It is firmer and more supportive than other pads. Quiet under foot. And the 7/16 is working well on stairs as well.

    Exceeded Expectations
    We needed a new padding for a large area rug in our living room...and with a new puppy the Lifeproof pad sounded like the perfect solution. I also needed a pad outdoors to go under a new outdoor batting cage in my backyard. We wanted to put a pad under the turf. Despite not being "certified" for outdoor use, the pad looks great and to-date has help up fantastic. Very happy with my selection...very happy with the feel of the carpet pad in both situations.

          Waterproof protection for my basement
          My wife and I have always wanted to refinish our basement but never did because of dampness. Then we discovered Lifeproof carpet cushion and our dreams were realized. Thanks to the waterproof and anti microbial properties, we carpeted our basement and made a great area for entertaining. We have piece of mind knowing our investment is protected. The pad seems durable and is very comfortable to walk on. Thank you Home Depot for having such an incredible product available.

            FINALLY a TRUE waterproof pad!
            After doing a lot of research I’m so happy I came across this carpet pad - its truly waterproof! I initially had it installed in my basement but I’m so happy with this pad I’m going to have it installed in my upstairs as well to protect my carpet against the kiddos and dog - definitely recommend!

              Finally, Legit Waterproof Carpet Pad!
              We finally decided to update the carpet throughout our home after being stuck here for the last year. Our entire family loves the feel of our new carpet with Lifeproof underneath. The padding is the best ever! Our living space is comfortable and cozy and the padding is more supportive than any other carpet pad. When our old pad was removed we noticed it was worn down and stained. My husband also said our rooms are quieter.

                We used this pad to go along with the lifeproof carpeting. We are very pleased with it so far. It has just the right amount of cushioning and we like the fact that it is completely waterproof. We would definitely buy it again.

                Premium Pad
                This pad is clearly superior to standard carpet padding. I am not sure what the equivalent support weight is, but I've compared to my existing standard carpet pad and this provides both enhanced comfort and support. I tested both the 7/16" and the 5/16" thickness with general use and point loading. Neither pad showed signs of permanent indentation due to the point loading. I will be purchasing the 7/16" thickness for my new house.

                  Went down easy. We are hoping its cushion feeling is long lasting and that it gives us a better R value than your standard pad. We installed it in our houseboat and installed your pet proof carpet over it.

                  This product was easy to install. Just remember when ordering that it comes in 40 square yard rolls rather than 30 as most carpet padding does. I chose this product because being waterproof combined with pet proof carpet makes for a durable and comfortable foundation for your feet in addition to your pet's too. I have had this installed for about a month and definitely meets all my expectations.
