I have no clue what is the actual name of the product, but I hope I can describe them well enough. Of course while watching tv late at night, I saw an infomercial for a product that you can put under couch cushions for support. They looked like white pieces of plastic. You could snap several pieces together for larger areas or take pieces away for smaller areas. The spokesman said they give a firm foundation. There would be no more snagging of the cushions, no more falling into saggy,weak cushions. I am not really sure how they work. You can put them under couch cushions, mattresses, bed frames, loveseats, etc. Has anyone else seen these products? Do you remember their name? Also, do you know if they work? Again, sorry, I do not know their name!
