Manduka Yoga Cork Blocks are made from sustainably sourced cork, which means they're pretty dense and firm compared to foam blocks. This makes them great for providing solid support and stability, especially for tougher poses like inversions or strength-focused moves. According to the manufacturer's description, they're made from cork oak trees without any toxic chemicals, which is cool if you're into eco-friendly gear.

But, keep in mind the firmness might not be for everyone. From what we've found, some folks think they're a bit too hard, especially in restorative poses or when you're putting weight on sensitive joints. So, if you need something softer and cushier, you might want to check out Manduka's foam blocks instead.

Also, they're heavier than foam blocks due to the cork material. While this is great for durability and staying put during practice, it can be a bit of a hassle to carry them around if you're heading to a class.

So, if you're looking for stability and durability and don't mind a bit of extra weight, these cork blocks could be a solid addition to your practice.

But if you need something lighter and softer, maybe look into the foam options.
