Review on 🦍 Gorilla Grip Original Non-Slip Mattress Gripper Pad - Queen Size, Prevents Bed and Topper Sliding, Versatile for Sofa, Couch, and Mattresses, Easy Trim, Durable Grips Prevent Slipping by Hesham Peltier

I didn't buy this for my bed but for my sofa. We have a microfiber daybed with very thick muslin on the underside of the cushions. They kept slipping off the back of the sofa, leaving a large hole between the back of the pillow and the back of the sofa. I halved one of those king-size handles lengthwise and placed it under the sofa cushions. While this doesn't completely stop the cushions from moving, we have to adjust them MUCH less often (every time we sit on them, rather than once every 2-3 weeks). I call it victory!
