  • It Feels Like a Different Bed!

    This product is a life saver! Our mattress has been horribly uncomfortable for months, with a major "dip" on my side of the bed causing morning aches and pains and a rough time sleeping. We couldn't afford a new mattress right away, so when I saw this product on HSN, I threw caution to the winds and ordered it. The difference is like night and day. It has really helped. I sleep through the night again, and feel much more refreshed in the morning. For the price, I hope it lasts awhile!

  • Converted Skeptic

    I was very pleasantly surprised. Wasn't sure this would work. A good friend has a very thick king size mattress with a pronounced crater right in the center of his side. I gave this as a gift and he said he had the best night's sleep in a long time. The Mattress Helper completely resolved the problem and he saved over $1000 not having to buy a new mattress as planned!

  • Fabulous idea!

    I ordered it for under my sofa cushions and it works very well. What a great idea. Only thing is that it is wider than needed. Any suggestions as to how I can fix that?
