Adds extra protection to your mattress while also adding warmth and comfort.Moemoe premium 500gsm mattress toppers are made in New Zealand using only natural 100% New Zealand wool. A wool mattress topper adds extra protection to your mattress from spills and accidents while adding warmth and comfort. Lightweight and moisture absorbent, wool insulates and breathes, regulating your body temperature, keeping you cozy in the winter and cool in the summer. Convenient elastic straps at each corner hold the underlay in place to prevent bunching. The underlay is fully encased in premium cotton to protect the wool.
