the description says the outer layers are organic cotton; what is the interior 'water barrier' layer made of?

Good grief Naturepedic's answer was annoying, not to mention cagey. All that lead-up made me feel like it was going to be something much worse between the cotton layers than it actually is. Why can't the company just say, "food grade polyurethane?"

Hi. I'm writing from Naturepedic. Your question is answered on our website. I'm quoting it here for you. "DrySleep technology effectively blocks liquids from passing through the fabric while still allowing the material to "breathe." This is achieved by allowing a certain amount of water vapor (similar to humidity naturally found in the air) to pass through. This results in less "sweaty backs" and a drier, more comfortable sleep. Vinyl/PVC, latex, and rubber, on the other hand, are comparatively "sweaty" - they block all moisture from passing through, creating a more uncomfortable sleeping environment. Drysleep uses a specially formulated polyurethane waterproof barrier that is proven to not leach harmful chemicals. It is made from the same grade material as is required for food contact applications. It also meets the highest standards for medical device biocompatibility (USP Class VI). It does not contain any fire retardants or antimicrobial treatments and is free of vinyl/PVC, phthalates and latex. It also easily passes the GREENGUARD "Gold" certification standards for chemical emissions. With a Naturepedic organic mattress pad, you never have to worry about harmful chemicals or allergenic materials. "

I don't know and I have thrown out the packaging already. I just know it covers against wetness. Sorry.

It is made of a dense foam (no coils) - it only states the cotton cover is organic, so would assume the foam is not. However, it did not have any chemical odors when I unwrapped it. The foam is a much more dense, (seemingly) higher quality than what came with the portable crib I purchased - firm, not a lot of give, but still soft feeling. Plus the organic cover seems to be of high quality. My grandson sleeps soundly on it. Note that the mattress cover is not waterproof. I purchased an organic cotton waterproof mattress cover to go over it and then covered all with an organic cotton portable crib sheet.

The label (in Chinese) says 100% polyester. The outside feels like fleece and the inside is stain resistant. Our dog threw up in it and it came clean with a simple wash.

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

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 heavy vinyl material. I've used it on two trips and have been satisfied with it. The cover/lid has a flap that folds down to cover the zipper. I feel comfortable saying it is waterproof and that you would have other bigger problems if something did end up wet!

The back of the package does not say what the membrane back coating is made of. The sleep surface: 80% cotton and 20% polyester terry cloth. Lining: 100% polyurethane laminate. Skirt: 100% polyester, exclusive of elastic. I hope that helps.

It is a fabric material. Good enough to prevent abrasions if you landed on the usual places like your hip or knee because of the reinforcement pads. It repells water, but I don't recommend it for constant rain. Got caught in a downpour, and couldn't hide shelter for 30 miles. The pants soaked through.

The top is 100% cotton. The bottom is waterproof but not plastic. Unknown what material it is made from.

It is resistant. As I understand it is made of vinyl. So it doesn't absorb water at all. No papaer inside,only plastic.

Better to ask the seller, but the bladder is some kind of plastic and the cover is either cotton or a thin but soft blend of some kind.

It is some kind of waterproof fabric. It does not leak and looks very nice. I have been very pleased with mine. It is also washable and resists mildew.

it feels like cotton and it is a totally decent material and thickness. very easy to get on/off. i however wrapped it in a waterproof sheet to protect it

There is some vinyl used as the waterproof barrier although it is covered up by a cloth-like material to protect it from damage in the dryer (use medium heat) and to add some more texture so it isn't slippery.

Neither of the other two answers even pretended to answer the question. Apparently the company indicates it's food-grade polyurethane. You can buy fabric coated with a layer of polyurethane, making it waterproof, for like 10 dollars a yard.

It is waterproof, but we use a thick organic cotton cover under the sheet more for comfort than anything else.
