Bamboo is a sustainable, fast growing plant. It is an environmentally friendly option to the foam blocks. It offers a natural look and feel to the yoga blocks.
Bamboo Yoga Blocks (also known as a yoga brick) are lightweight (usually hollow core), strong, and stable. They are much more resistant than foam blocks, meaning that they do not give. The drawback to these wood blocks is that they can slip if not properly placed. The drawback to the foam blocks is that they are chemically-made and can emit an odor when they are new (some people are more sensitive to these odors).
To clean your bamboo yoga blocks: Always follow manufacturer's directions on cleaning any of your yoga props. Generally, however, you can spot clean your yoga blocks with mild detergent and then towel-dry or allow to air dry.
When choosing yoga blocks, you may also want to look for blocks that have beveled, or rounded, edges. The beveled edges make it softer on the hands when gripping and also on your back when in support poses.
