"As seen in the picture, I use the pebble 3/4'' tiles for my home gym. I was concerned about installing a workout area in a room with a tile floor, so I elected to go with the thicker foam tiles. Greatmats was awesome- I requested three samples from them, which arrived quickly and were free! It was extremely helpful being able to compare the densities, weights, and textures of all three samples side-by-side. The other two samples were roughly a half-inch thick and it was apparent the 3/4'' was the way to go for my purposes. I try not to drop any weights- more to take care of the equipment than out of a fear of damaging the underlying tile- but I love the peace of mind the mats give me to set down a deadlift relatively firmly or letting a weight slip out of my hand and not have to worry about any damage to the floor below. The density is perfect- firm enough to not feel 'squishy' underfoot (I was concerned about my feet sinking in and being unstable during squats, but that hasn't been an issue), but still enough cushioning to soften a weight being dropped. Installation was a breeze- I went to Home Depot and bought a 3' straightedge which helped tremendously. Because I installed wall-to-wall, I had to trim about a half-dozen tiles. Just make sure you have a fresh blade on your utility knife and the cuts will go much faster. I have yet to mop it or spill any water on the floor other than sweat, but I haven't noticed any liquid seeping through and they're very easy to sweep/mop up. Excellent product- I actually plan to buy a few more to finish off the room!" - Allen, San Diego, CA https://www.greatmats.com/flooring/exercise-room-flooring.php
