Great for a small indoor play area. Not designed to have furniture planted on it. Easy to put together, easy to take apart and store. Interlocking pieces stay together.Not too squishy. Density is perfect to "soften" my hardwood floors -- "soft" like wonderfully flexible cheap flip-flops. Priced well enough to have a another one in a second room -- comes in a 48 square foot pack as well. Would love to see a version of these tiles with a beveled outer edge.One of the kids said to write, "Makes my knees happy!"
