The Futon Stop Slip, or Mattress Grip Pad is an essential accessory for any Futon Mattress. The Stop Slip keeps your mattress in place during use for a hassle free futon that won't need so much readjustment to keep in its optimum and most beautiful position. No more slipping and sliding with the stop slip. Its made of a non-slip foam, the same kind of material used to keep floor rugs in place (and it works for that too!) It really works and will reduce the amount of times you need to adjust your mattress while keeping your futon looking great.
