Awesome Pillows!
Color: White, Size: King (Pack of 2)
These pillows are super soft! I love them. I bought them when I caught a bad cold and needed to prop myself up. Worked so great! Definitely give these pillows a try. They're very reasonably priced too.

Exactly What I Needed! Comfortable, Protective & Great Fit
Color: Grey, Size: King (Pack of 1)
I bought the Utopia Bedding Waterproof Mattress Protector (King, Grey) after some recent accidents from my toddler and let me just say—it’s a lifesaver. First off, it actually fits my king-sized mattress perfectly and stretches easily over the 14-inch depth with room to spare. It doesn’t bunch up or slide around like cheaper ones I’ve tried. The elastic is strong and holds in place like a fitted sheet. The grey color is sleek and neutral, which is a nice change from the usual white protectors. It’s also surprisingly soft and quilted, so it doesn’t have that crinkly, plastic feel you get with some waterproof covers. You’d barely know it’s a waterproof layer—zero noise when moving around at night. As for protection—it passed the test. We had a minor spill and it didn’t leak through to the mattress. It washed easily in my machine and came out looking brand new. For the price, quality, and comfort, this mattress protector is an excellent buy. Highly recommend if you have kids, pets, or just want to extend the life of your mattress!

Great for protecting my beds soft , quiet , and easy to clean
Color: Grey, Size: Queen (Pack of 1), Color: Grey, Size: Queen (Pack of 1)
I had to purchase since a family member had surgery and wanted to protect the mattress. It is a sleep number and this waterproof cover fit good and I like that it is not noisy. I am considering purchasing for the other beds in my house because I like it so much. It is soft and quiet and waterproof, Good product. I like the different colors available.
