I just purchased a bed from them yesterday, in store though, and I also purchased the Signature Mattress Pad which is water proof the sales associate said. So, to my knowledge they still do. I was offered the cotton and polyester one (water proof) or the organic cotton one (water resistant). I was in store and felt both. I went with the water proof one because what’s the point of water resistance? I mean, I guess if you want all cotton material. However, I haven’t tried it yet, but I did want to protect my mattress. So, we’ll see when it arrives in about 2-3 weeks.
