You'll fall in love with our 4" Wood Yoga Block! Made from 100% New Zealand Pine, these blocks are as practical as they are beautiful. The availability of New Zealand pine as a renewable, sustainable resource makes it an attractive alternative material for yogis concerned with protecting the environment. Our natural wood yoga blocks are sanded smooth with beveled edges. And because this block is from nature, no two are alike. Each wood yoga block has its own unique wood grain character. The 4" wood block is extremely sturdy and durable, providing excellent support and stability for proper alignment.
