  • Floor mats are not just for the Gym

    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.

    • Did the product fit true to size? yes
    • How is the quality of the product? good quality
    • Was the product free of any manufacturer defects? yes
  • Basement Play Area

    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.

  • Not really for gym

    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.

    • How accurate was the sizing? perfect
    • Please tell us about the quality of the product. not very thick
    • Was the product free of any manufacturer defects? yes
  • TNT Foam

    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.

  • Very soft

    I wanted something under my area rugs. I have concrete floors and grandchildren. These tiles are the perfect solution. They would work well anywhere you need cushion. I don't have any problems with them coming apart or sliding.

  • Perfect for a workout space.

    The product is exactly what was advertised. The blocks are perfect for working out.

  • Interlocking floor mat pieces

    The comfort of these beauties help with pressure produced by years of outdoor labor. These pieces can be put together making various size configurations, so can be used as a runner for a work table as well or padding for standing at a work station. It can be taken apart and reconfigured in another area, at another time for another purpose. I am very happy with my purchase.

  • Great Mats

    Easy to put together. Took only a couple of minutes. I'm using them on my cement floor. They are providing an amazing cushion for me. I am going to order some more for another room.

Answer This Question

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 overstockcustomercare1 on Jan 23, 2013
