So I did it get to use the sheet. It was way too small. I did read the description about the measurements but I just figured it would cover like a whole twin size bed. It's like a square that covers for an adult... I was using this for my toddler and she peed right on the bottom of where there's no protection. So this product may be good. I don't feel like I can properly rate it. Just sharing my experience with it.

These are waterproof but I do not like the other side. It is fibrous and does not hold together like a woven cotton layer would. Why do they have to make things worse when they improve them?

Great pad for a queen bed. Covers the full width of the bed and completely protects the sheet from accidents.

The best thing since sliced bread. I was getting ready to sew some extenders on the protector we had BEFORE I found this. My husband would take the old one and use it as a blanket! Alzheimer's. But this one has stayed in place since we started using it. Thank you so much.

These pads work very well. They are washable and come out of the washer like new. They stay in place even without both "tabs" being tucked in. We wish they held more liquid (I would not call them "waterproof"); we have had a couple of times where Dad has soaked them through to his bed (but it may have been because the pad was ill placed too!) but I have resolved that problem by putting two (one of top of the other) on the bed. We had been using disposable bed mats (the ones with adhesive strips) and they would not stay in place and were expensive (we were using 2 or 3 a day). I have bought 4 of these mats so far and will be purchasing more to be used in Dads RV. The 36 x 54 works well on Dads full size bed. The waterproof part does not cover the entire width of the mattress but it doesn't need to; we only need coverage where Dad lays. I went to Dads at 5am today and was able to remove the pads and throw on clean ones in less than a minute so he could lay back down on his bed. Wish I had found these mats sooner!
