Literally any rug or piece of carpet big enough to fit underneath at least your kick drum, hi-hat stand, and two or more legs of your throne, since it's actually your body weight on the rug with your drums that keep them from moving; that is also stiff enough to lie flat on its own, with high enough pile to grab your spurs. End of list. Ease of transport? My drum rug for nearly two decades now has been a 3x5 commercial rubber backed doormat from Home Depot. I roll it up and throw a camping strap around it and toss it in the back of the truck. Couldn't be easier. The ideal price to pay for a so-called "drum rug"? $0. The first place to "shop" for one at that price? Your own garage, your grandma's basement, your neighbor's garage, or anywhere else where someone you know has that one old rug rolled up not doing anything, that they would gladly just give you. There is absolutely zero benefit to purchasing a so-called purpose-built "drum rug." Every last one of them is simply a regular rug, with a dumb drummer surcharge added to the retail price. Don't pay it. Now, if you see one that you simply like and want, it's a free country, and it's your money. But the bottom line is this: Every drummer needs a rug under his drums. Absolutely no drummer on earth needs a "drum rug." Answer from ItsPronouncedMo-BEEL on reddit.com
