I purchased this mattress topper for under $27 and I'm so impressed that I'm planning to buy another one! Easy Installation & Perfect Fit: This topper was incredibly easy to put on, and it fits my California King mattress perfectly. The 18-inch deep pockets ensure it stays in place - I can move around on the bed and it doesn't shift at all. Comfort: The topper is wonderfully soft and has made a noticeable difference in our sleep quality. My husband absolutely loves it, and we both wake up feeling more rested. The Ultimate Test: My son recently came home after being deployed for a year. He slept on our bed for hours and immediately commented on how soft and comfortable it was. That's saying something for someone who's been sleeping on military accommodations! He was so impressed that he's planning to buy one for his ship. Bottom Line: For the price, comfort, and quality, I recommend this 100%. It's hypoallergenic, stays in place, and has exceeded all our expectations. You can't go wrong with this purchase!

Mattress protector

Size: Twin

Arrived quickly. No factory odor. Was "scrunchy" out of the package, but fit snuggly around the twin mattress and doesn't make any annoying noise. Basic protective mattress topper. Water proof, but breathable, no condensation under the sheets. Disappointed there wasn't more "fluff", but does the job of protecting my mattress from coffee spills and natural body sweat in between weekly washing. I've had it a while, and it seems to be holding up with monthly washing and drying.
