What is the waterproof material? Is it polyurethane?

Yes, the underside is polyurethane laminate. The top is 80%cotton/20%poly terry cloth. The label says it is safe to clean with boiling water.

To prevent heat buildup keeping our protectors cool and noiseless, the surface material is made with soft cotton terry back coated with a breathable polyurethane membrane. To ensure a great fit, an elastic band is used on the side skirt to automatically pull excess material under the mattress.

It's plastic and waterproof... When I got mine the creases from where it was folded up got on my nerves so I washed it but I didn't let it go through the spin cycle... It got the creases out but it changed the texture of the curtain . I actually like the look of it better now

It's made of food grade polyurethane (according to their website). No waterproofing is organic, but you have to decide if the trade off is worth it for you. Honestly, I'm still back and forth on this myself! From my research, this does seem to be the best (or one of the best) organic waterproof mattress pads out there.

A good question!! Unfortunately I have not tested to see if it was waterproof. I am sorry.

This is made of woven propylene, my girlfriend bought it to carry make up and stuff like that and until know it has worked fine. It wont be waterproof due to the zipper. Hope that this helps!

Yes. The label says that the waterproof layer is made of a polyester-backed vinyl.

It is fabric, not plastic. It does not repel water. You would have to use a liner with it.

There are few things that are truly waterproof. I would say it is very water resistant. That said, I have had it on my 7 foot drop waterfall for 6 months now and I have experienced no leaks, not to say it may not in the future. It is the best material I have found for such a purpose, This foam provides great adhesive ability to hold rocks together combined with water resistance.

It is not waterproof. It has a silicone cover you can put on it for water protection.

Yes it is waterproof BUT I have already gone through 2 of them because of their construction, they are not well made, and they break after about 2 months. I know it is because I take it off and on, but if you just keep it on im sure it will last longer.

The bottom is sealed plastic. Yes, it is waterproof. My little girl left plenty of puddles in it and it never leaked.

I haven't had mine for to long but it appears to be made from some type of light weight nylon. It is water resistant and the tie downs work well. It has a four year warranty.

It is a plastic material, fairly weather resistant (but the sun will affect it over time). It is waterproof in the sense that water will stay in the bottom reservoir without problem. It is a decent quality plastic (not overly thin). I have had some of them for three years, and they all still function well.

It is water repellant. As far as water proof, I'm not sure about that. I have not had it out in any big rainstorms yet.

It is a double layer of gel and it is waterproof, of course if the material is torn then it is another story.

The material is similar to backpacks and briefcases. I would guess it's water resistant, but not waterproof.
