SagsAway Ultimate Sagging Innerspring or Latex Mattress Repair System. Directly Target A Sag In Any Twin, Full, Queen,or King Size Up To 14 Inches Thick. Not for Memory Foam, Tempurpedic, or Air Beds

No Sags is different - this solution has nothing to do with the size of your mattress - but the actual depth and size of your sag. Covering the entire mattress would only bridge the sag temporarily and then sag again in the same spot. You want to TARGET the weak spot to push up and fill-in with the size and depth you measured for. As stated in Step 1, this cannot work with memory foam, air, water or sofa bed mattresses, because the effect is absorbed rather transferred to push up a sag. Most of our negative reviews come from those who ignore step 1 and have the wrong type of mattress. Another common mistake is adding too much thickness creating a hump. This is simple, you want to fill in your sag depth measurement to level your sleeping surface. For example, if you have a ½" sag and you use a 1" thick Standard, it's going to be too much. If you have a 4" sag and use a 1.5" Standard Deep, that's not going to be enough. Some sags are simply too deep for this to work. Anything over 3″ deep is not a sag, it's a crater and it's time to buy a new mattress. It's simply a matter of inserting the right amount of support for the sag depth you measured for. You determine and control how much support you need. OUR SOLUTION was finding a durable military grade foam ideal for support with the cushioning and recovery properties needed to act as a shock absorber for mattress longevity. While it may not be impressive or looks like common foam like polystyrene, it's not. It's chemically different and used in the aerospace industry. NO SAGS won't deteriorate like typical mattress foam. Your mattress will continue to sag over time and may conform to the support creating an impression underneath depending on your mattress construction. You can add Posture Zone Supplemental Support for deeper sags now or in the future as needed. NO SAGS is a patent protected DIY Targeted Sag Solution and is neither a medical nor an orthopedic device. 80% of those who follow the 3 Steps and learn how to
