Totally worth the price!
Color: Lagoon, Style: 2 Blocks
These are great blocks! They are soft yet supportive. Used for yoga, Pilates and on the sits-bones when meditating. All purpose, perfect size, cute, calm color. I have two sets, I like them so much; one for the house and one in the gym.

Highly Recommend Gaiam Yoga Blocks
The Gaiam yoga blocks are excellent quality and a must-have for any yoga practice. They’re lightweight yet very supportive, making it easy to maintain proper alignment and balance in a variety of poses. The foam is firm but comfortable, with a non-slip surface that stays in place during practice.
These blocks are especially helpful for stretching, improving flexibility, and modifying poses, whether you’re a beginner or more experienced yogi. They’re durable, easy to clean, and hold their shape well over time.
Overall, Gaiam yoga blocks offer great value and reliability. I would definitely recommend them to anyone looking to enhance their yoga or stretching routine. 🧘♀️✨

Good for dancers
Color: Lagoon, Style: 2 Blocks
My daughter is an Irish dancer and got these to practice keeping her legs straight. After using for a month we can see a difference. They are sturdy and decent quality. Would give 5 stars but our friends have some that are more comfortable.
