  • Floor mats are not just for the Gym
    Verified Purchase

    This is the second time I've purchased these mats for my garage. I keep adding to them. I have a studio in part of my garage, and I put the mats down and a carpet on top of them. Not only do they insulate but they help relieve the fatigue from standing all day. I gave a four star rating instead of five because the borders are useless. They don't lay flat and some of them don't fit the mats at all. The manufacturer could leave the edges out and put in a couple more mats, which would be more helpful, I just threw the edges away.

  • Not really for gym
    Verified Purchase

    we ordered these to set up a small home gym area in our basement. while they are very easy to put together, they don't really stay together very well when exposed to impact movement like aerobics or floor work. Also, they are not very thick so they do not provide much support on top of a concrete floor. Maybe with indoor/outdoor carpet underneath it would be more suitable.

  • Basement Play Area
    Verified Purchase

    We installed these into our basement as a play area--holds up well. Couple tips to get the most out of these mats is to use either a thin grip pad underneath, or slip under the wall/floor joints to prevent slipping. We did the latter--they slide under the gap between the sheet rock and our basement floor with the help of a screwdriver to push them through--works great and no sliding panels. Another user said to cut the extra panels to use as end pieces--we did this as well--worked great. Held up well enough so far--all in all a good solution.

    The price for this item is not bad, I will say it is adequate. The bad thing about this product is the lack of borders to complete the mat. The borders are not available for purchase as a separate item either; therefore takes away the presentation of the product.

    Bought these to make a home gym in our garage. They are perfect and exactly what we were looking for. They are the perfect height - not too thin and provide the comfort that we were looking for! I would highly recommend this product.

    Easy to put together. Worked perfectly on a basement cement floor where we set up exercise equipment and a weight bench. Even after multiple workouts and weights being dropped, the pieces stayed together.

    We bought these quite a while ago for both our home gym as well as to put under our treadmill and elliptical. They have stood the test of time well. We didn't glue them down or anything, so they do move around a bit. No issue with the thickness, they are perfect for what we needed and much more economical.

    Solid mats that provide a lot of cushion and are easy to connect together. Can't really beat 48 square feet for under $60 either. I've bought multiple sets of these now.
