The perfect mattress protector. As advertised, it is the best mattress protector i have owned. Soft, breathable, high quality materials. Fits perfectly. I have nothing to complain about. 5 stars!

Great Mattress Protector. We love these mattress protectors and wish Riley would restock the King size! They work well, are a good material, and wash nicely.


Wish KING were in stock. I love this protector, works incredibly well. It is oversized, so it doesn't fit perfectly tight without working it under the mattress. That is a drawback, however, in terms of protection - it works incredibly well. I wish the King size protector were in stock.

Great sheets - love the feel and easy to maintain. The mattress cover provides strong protection. Can’t wait to use throughout my home.

Amazing!. My husband and I both sleep pretty hot and our current protector literally makes me feel like I’m on fire. It’s hard to sleep and stay comfortable. After finding this Riley protector, I don’t even want to leave our bed. The material and quality of the tencel is truly top notch. Can’t ever go back to a different protector!

Just what I needed

Breathable Mattress Protector. The search is over. Finally, a breathable mattress protector that doesn't leave me feeling hot and sweaty. I had previously bought one from Target, and though it was affordable, it did not breathe well, and the polyurethane liner got messed up when I accidentally washed it in hot water. Anyway, this Riley mattress protector is great. My partner sleeps hot but I've received 0 complaints about the bed feeling too hot since we started using the Ultimate Tencel Mattress Protector. I couple the protector with percale sheets (sateen is no good if you sleep hot), and the bed feels great.
