  • 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.

  • TNT Foam
    Verified Purchase

    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.

  • i need to cover a 15x15 feet square space how many boxes do i need

    • Hello kendyloy, thank you for your question. You can use this over carpet. Thanks for shopping with us! Shelia B

  • Good Day, Please advise. Are the 36 edge pieces referenced included in the 48 total mats cited? as in do you receive the 36 edge pieces and 12 square pieces? or is it 48 mats and 36 edge pieces? total 84 pieces in an order?

    • Hello ryantlemieux, We're sorry for the confusion. A total of 12 non-edge pieces is included. The rest are edge pieces. I hope this helps, thanks for shopping with us.

    • TO: overstockcustomercare1 Your answer does not make sense. If each mat is 12"x12" (One square foot) and only 12 are included, then the mats would only cover 12 square feet, not the 48 square feet as described in the title. According to the product description, there are 48 mats (48 square feet) and included are 36 edge pieces for a total of 84 separate pieces. Please correct your answer.

  • how well do they work and an old concrete flood that is uneven in places

    • Thank you for your question oldmagoo. Perfect! most of the mats purchased, are for use on a concrete floor. Garages, basements, outdoor patios, bars, schools, etc. The mats provide a nice cushion. Have a great day.

  • I'am trying to cover a space that is 12 feet x 19 feet how many boxes would i need

  • Are the joints waterproof? I am wanting to use outdoors around a hot tub deck. Can water get through seems/joints to penetrate subfloor?

    • Hello dtuffy118, These floor mats are not waterproof at the joints, you may need to install a barrier to prevent damage to your subfloor. I hope this helps, thanks for shopping with us.

  • Will this product hold up to having cars parked on them in the garage?

  • I have a 12 x 12 space. How many boxes do I need. Also a couple of people have complained about there not being enough edge pieces? Is that true?

    • These very functional gym mats have 48 in a box so you would need at least 3 boxes. I am very sorry but I cannot attest to other customers saying they did not have enough edge pieces, their project may have been different than the one you plan. There is suggestions in our customer reviews on ways to make more borders if you do end up needing them. We have a very helpful customer community! I hope this helps you will all you need, please feel free to contact us any time

  • I have an area that is 18 feet x 21 feet .. how many mats or cases would I have to buy??

  • Dimensions are confusing; exactly how many tiles, how many edge pieces; and is the total dimension or amount of floor space these will cover in feet or inches? If this really covers 26 feet by 14 feet by 13 feet, how does the math work with 12 inch square tiles?

    • The dimensions for this item are correct. Each mat measures .5 inches thick x 12 inches long x 12 inches wide. You are getting a total of 48 mats.
