Stacking blocks in order to accommodate taller or less flexible yogis can be an unsafe proposition. That's why we are pleased to offer you a 5" Big Foam Yoga Block, an over-sized block made out of the same lightweight, super-dense foam as our regular-sized blocks. The block stands a foot tall, with a generous 6-3/4 inch width and 5 inch depth for extra stability. Our foam blocks are made from a sturdy, scratch resistant foam. Each block has beveled edges for added comfort. You will find these blocks to be very strong and durable, and yet incredibly lightweight and comfortable. This block is ideal for use in standing poses, as well as in supported poses. Foam blocks provide the support and/or height needed to do poses safely and effectively. Block measures 5'' X 6-3/4'' X 12''.
