The airCORE technology makes this bolster light weight while actually improving on stability and cushioning.
The air filled pockets resist sagging that is usual with cloth filled bolsters.
The outer cover is made of eQua microfiber which is inviting to touch. The bolster cover is machine washable too.
These Manduka bolsters take care of the environment too, with the airCore construction made from post-consumer recycled plastic and 100% cotton.
