Keep mattress in place and stop it from slidding off your boxspring. Stop re-adjusting your mattress every morning. Let the No Slip Oval Pad keep your mattress securely in place. The No Slip Oval Pad is made from Polyurethane foam right here in America. It gently grips you mattress and boxspring in place. The No Slip Oval Pad measures 33x66. It is perfect whether you have a dust ruffle or just a slippery mattress. And it is easy to use. Simply place the No Slip Oval Pad between your mattress and boxspring then sleep easy knowing your mattress will not slip away in the middle of the night. If you are an overactive sleeper, or you use a dust ruffle over the boxspring, chances are that you are having trouble with the mattress slipping off the boxspring at night. Our No Slip Oval Pad (100% American made Polyurethane foam) keeps the mattress in place even if they are both wrapped in plastic. No clips. No Pins. No elastic bands. Just a piece of foam! It?s so simple; just put the pad between your mattress and boxspring. That?s all there is to it! The 33x66 polyurethane foam pad is just large enough to keep your mattress in place but small enough so that you don?t see it. And it?s thin enough so that you don?t feel it. (For King size we suggest using 2 oval pads.) **NOTE: The actual product may vary in color from the image. Actual color may be a bit darker grey/black color foam. The dark grey/black foam is more difficult to photograph so we used the light grey for the image.
