This is one of the best mats I have used. I just had spinal surgery 2 months ago and needed a mat that is thick and firm. The mat is perfect for my size. I am 5 “11 and weigh 180-184 pounds. The mat doesn’t move much and provides enough support on my back that doing Pilates, yoga, and exercises is comfortable and somewhat painless. This has helped my mobility and confidence in my rehabilitation. Overall, this is a great mat for the price, lightweight, and is easy to store away.
