Shopping Advice Needed: A Mat to go under play structure in basement

So I was thinking that for the winter I'd bring my daughters little tykes clubhouse climber into the basement.

This is it:


For safety, I think I should put some sort of large mat underneath.

Any suggestions for where to find the cheapest largest mat possible?

I had a climber in the house too. I had it right on the wood floor. If you do want some padding, what about a cheap area rug from HD?

i was thinking an area rug, plush or one with a good pad under it would do the trick

You could get the Step 2 2'x2' foam mats. They sell a four pack at TRU for $20. They are very sturdy and pretty thick.
