Very soft and comfortable
Color: Black, Size: 1 inch
I really love this yoga mat. It has the perfect balance of comfort and support, so it feels soft enough on my joints but still stable for workouts and stretching. It doesn’t slide around on the floor, which makes me feel more secure during poses. The grip is really good even when I start to sweat, and it’s easy to roll up and store when I’m done. I also like that it’s thick enough to cushion my knees and back. Overall, it makes my workouts more comfortable and enjoyable, and I actually look forward to using it.

As Advertised.
Color: Boysenberry, Size: 1 inch
The boysenberry color is pretty. The Retrospec mat is odor-free, 7/8” thick (so close enough), dense, and non-slip on my wood floor. I wanted the density to cushion pressure points whilst performing various core exercises and general stretching on the floor. It works well for my purpose. I agree with other commenters, the 1” thick mat is too unstable for yoga. That said, the slight instability makes this mat useful for developing balance and core stability by balancing on uneven surfaces, similar to the benefits of walking on grass or trails. The mat is easily nicked by long nails (human and animal) rocks, sticks etc. so pay attention to where you set it up; however not a deal-breaker for my use. I originally looked at the BalanceFrom GoCloud mat because it is the mat that appears in several online reviews with a link to Amazon. However, once on Amazon, I noticed remarkable similarities between the GoCloud and Retrospec reviews. I suspect both mats are identical just with a different brand name and sold by different companies. I ultimately went with the Retrospec mat because the Retrospec is sold and shipped by Amazon so the benefits and protections of “Amazon Prime”, including free returns, apply. The GoCloud mat could be returned however according to the fine print, if the return wasn’t due to Seller’s error the return might be subject to a restocking fee. One of the most objectionable review comments common to both brands had to do with the mat having a terrible, lingering odor. I was willing to take a chance and order it, but would have returned it if it had a bad odor. I did not want to pay a restocking fee so went with the Retrospec mat sold and shipped by Amazon. One exception is Amazon Prime offers the GoCloud in black only. I didn’t want black because I expect to occasionally use it outside in the Florida sun and it will get really hot.
