Great quality, I decided to put it to my new mattress and it fits like a glove. I hope it lasts longer for the price. It feels like fabric, not plastic. It was really easy to put on my mattress.

### ⭐⭐⭐⭐⭐ Nice, good for 12" mattress. Full protection.
*by B***T on February 3, 2026*

These have been great so far. They've endured a few months of use so far without leaking. Easy to put on and remove and wash if needed. We use them for bedwettting paired with rewashable pads, so this one doesn't need to be washed as frequently, which is nice. They seem durable, and I like how they cover the entire mattress (instead of just the top.) These are made for thick mattresses, and they fit well. Good price for multiple.
