I purchased this mat to replace a gel mat purchased from Costco about 4 years ago.  It's initial cost is a bit higher than other gel mats but it's worth the extra money for several reasons.  Most of the other mats you see advertised are about 1/2 inch thick gel layer sandwiched between two sheets of vinyl and heat sealed or "welded" on the edges.  Over time, the edges tend to curl creating a tripping hazard and the top vinyl sheet eventually wears out.  This mat is a 3/4 inch thick solid piece of material with beveled edges. It's not a sandwich.  It lays flat on the floor, there are no heat sealed edges to curl.  The beveled edge means a smooth transition from the floor (our Roomba loves it)  .Being described as "Commercial Grade", I expected it to be more like a piece of hard rubber but it is very "cushiony" and feels great to my very tender feet (medical problem) when I step on it, even through shoes.  It is a very substantial mat and given proper care, it will probably never need to be replaced.  We have this one in the kitchen in front of the stove.  My wife fell in love with it the first time she stepped on it as did I.  I'm considering purchasing another one for the laundry room.  Not as "pretty" as some of the "sandwich" gel mats but it cushions better and isn't that why you buy a mat in the first place?
