    Great Option for older, beginner workouts
    Color: Gray, Style: Yoga Mat
    I am a 54-year-old woman with multiple issues dealing with my weight, knees, and hips. The support of this particular mat is thick enough that there is no pain when being on my knees or lying down. It does not pinch your pressure points, causing pain as a thinner mat would. I am very pleased with the quality of this mat; it feels durable and I do not worry about my flopping around and destroying it while I learn the proper positions I need for my exercises. The length and width is sufficient for my 5 foot 11 inch height and extra girth. I was not looking for anything in particular in terms of design or color, as I prefer functionality, and this is to be used at home as a beginner mat while I start my exercise program.

    Great Quality Mat for the Price
    Color: Gray, Style: Yoga Mat, Color: Gray, Style: Yoga Mat
    After burning through several cheap mats that curled, bunched, or wore out within weeks, this one finally got it right. The 1/2-inch high-density foam provides real cushioning, my knees and wrists feel the difference immediately, and it holds its shape without feeling unstable during balance poses. Grip is solid on hardwood and carpet alike, and the included carry strap is a small but genuinely useful touch that makes hauling it to the gym effortless. It's a bit bulky for travel, but for home or gym use it's hard to beat at this price. The quality speaks for itself, this feels like a mat built to last. Highly recommend.

    This is very good
    Color: Purple, Style: Yoga Mat, Color: Purple, Style: Yoga Mat
    It’s a really good size and quite soft; the only downside is that I think it’s a bit pricey. It’s a good option if you don’t have other choices, but if you can find something better, do so.
