I love this topper when we first bought it. Almost a week after we bought it our son had an accident through the night, and I had to wash the topper. It specifically says this is machine washable. After I washed this topper, it shrunk to the point that it didn't completely cover my bed anymore. I believe this shrinking is what caused the stress to the straps, because less than two weeks after I washed the topper the first time, one of the straps broke. Thankfully my fitted sheet holds the topper in place enough until I can buy a different brand for a replacement.
