Problem with rug in playroom?

Question

I bought a rug for my sons playroom and its been such a pain. Its a very thin area rug thats I think 8x4. I just wanted something to keep the wall to wall carpet underneath looking semi nice! Anyways...the carpet keeps bunching up and moving. He has a hard time playing on it due to how it ripples when he sits on it. Is there anything I can do to make it "stick" to the carpet any better? Like I said the rug is very thin and has a kind of rubbery underneath to it.

Answer 1

Duck tape or two sided tape under the area rug.

Answer 2

two sided tape will work
