Perfect For My Routine
Color: Black
I am retired military, so exercise has always been a part of my daily routine. Since the pandemic I have had to adjust, which is hard because the gym has the equipment I have become accustomed to. I didn’t realize how different it was working out there as when I started to work out at home on my hard wood floors (no carpet anywhere). I thought it would be easy but the military exercise mat is entirely too thin and was making my tailbone hurt tremendously, so I had to give up my sit-ups and some other ab exercises. This kind of threw a wrench into my routine and I could start feeling my motivation go away. I decided to take a look on Amazon for a thicker mat. I should have done this long ago because I found this one I’m writing about. It’s the shape of any typical exercise Matt except it’s 1” thick. It appears to be made of a type of foam (not bothering to look at the description right now). When I pulled it out I thought I was going to sink in making sit-ups even harder but it’s firm but not hard. I like it better than what is at the gym. Durability will be hard to determine until I’ve had it a while but I’m definitely excited to start back up on my exercises.
I recommend this mat if you have hard wood floors, bad back, bad knees, etc.
I thought I read some negative reviews about mats this thick because of yoga and balance but I beg to differ. If balancing is part of your exercise routine, then a mat which makes balance harder is exactly what you want. Exercise is supposed to be challenging and you need to work harder to see a difference. If that isn’t your goal or if balance is a medical issue, this may not be the right mat for you. Something you may not think about is I have chronic foot pain and this mat makes it less painful for me to stand or jump.
For me, this mat is perfect.

Extra Cushioning for Comfort
Color: Red
This mat is thick and cushy - even with meniscus tears in both knees I can comfortably exercise. And I love the color.

Nice, thick & comfy but came w/ punctures in foam; seller provided discount
Color: Purple, Color: Purple
I love the mat. It's thick and very comfortable on my knees. However, when I opened it for the first time at my yoga class, there were several cuts or punctures in the foam. I attempted to return it and the seller offered me a 10% refund due to the damage. I am concerned that the mat may deteriorate due to the damage it came with, but I need it and have no idea if the cuts will matter over time. So I accepted the $3 refund and am keeping the mat.

Great workout mat
Color: Green
It’s very thick and soft so it makes exercising a lot easier. It rolls easily ready to store. And it seems very durable. It is also flexible for certain exercises for balance.
