Seeking recommendation for waterproof nontoxic mattress protector

[daddycat]

Anyone have a recommendation for a waterproof and nontoxic mattress protector? It has to be waterproof. Organizations like OEKO-TEX certify nontoxic materials.

Neoprene? Used for wetsuits. You can buy it in rolls. Sew with a flat lock seam and seal with a special glue.
Walmart sells many waterproof mattress covers at various price points, but I don't know about toxicity.

I don't know where you are located, but here is a company that sells quality products in Quebec, Canada. They are on the high end of pricing though...

I could not afford these and chose to buy at Walmart or Amazon after doing some research.
Brand: AllerEase
All our mattresses are encased in an anti-bed-bug waterproof zipper bag. On top of it, there is another waterproof mattress protector that is easily removed for washing. All our pillows are also encased in anti-allergic (dust mite) zipper cover. They seem to be of decent quality because we've had them for 10 years and they are still in perfect condition. No bad smell either. So I would think they are not toxic.
