My 2 1/2 year old was constantly leaking through his nighttime pull-ups and I was worried he was going to ruin his mattress. I chose this mattress protector because of the great reviews and so far it has worked wonderfully! He isn't leaking through his pull-ups much anymore, but when he does the mattress protector does its job perfectly! When deciding on a protector I wanted one that wouldn't make a crinkly, plastic sound when lying on it. I think for a waterproof mattress protector, this is the best you are going to get as far as it not sounding plastic-y. If you just put a sheet over it, it is going to feel a little plastic-y and there is kind of a plastic-y sound, but it is very minimal. I put this mattress protector directly on top of my mattress and then put my regular mattress protector on top of it. This completely masks the water-proof protector and one wouldn't even know it was there. I would highly recommend this to anyone wanting to protect their mattress!
