Review on Waterproof Cotton Terry Mattress Protector Cover - Deep Pocket, Breathable & Noiseless Bed Cover for Kids, Adults, and Pets - Fits Mattress Pads Up to 14-18 Inches by Dustin Mitchell

I bought a California King size for my adjustable bed and it fits great. Doesn't slip or slide when the bed changes position. I have an incontinent pet that sleeps with me so the bed is changed frequently. The mattress topper has been washed at least half a dozen times and is still as soft and durable as the day it was brand new. Fully protects the mattress and believe in places where the stains are not small. I can't say enough good things about this cover. It takes a little while to dry due to the waterproof backing, but I'm fine with that. I just ordered a spare bed so I can change my bed and not have to wait for the first one to dry. It's lightweight and doesn't take up any more room in my linen closet than a fitted sheet, so having a spare is great for me.
