on initial glance the price seems insane... n it is. allmost $200. however after looking everywhere ifound there is nothing like this in the entire market. first of all its organic cotton gots certified. not made in china, it actually fits my around17in king mattress set up with enough to tuck in all sides. 13in cirti pure Sealy Posturepedic 4 in organic dunlop latex topper with a 2 to 3in organic wool matress pad. mp has a thick wide strong ring with good grippy rubbery hold. iwashed it once so far no shrinkage no pilling. it is nice heavy built. it does not at all feel like plastic its kind of hard to tell it has a waterproof membrane. in the entire time iwas looking for a waterproof organic mattress protector on the web, amazon ihave not found anything close to this. it does come with like a year guarantee but for this price i look for it to last much longer nonetheless based on prior experiences with whisper organics customer service ifeel confident if ihave any problems they will be there to help me. however its abit steep imean its allmost 200$ ihad to dish out but with all that i wanted there was no one else who could deliver. plus only have one bed. so all things considered worth it to protect my investment. iwould recommend this whisper organics waterproof mattress protector based on my experience so far. js
