Irisette Neck Support Pillow Piet. The surface of the neck support pillow features a textured design. This special core made of viscoelastic foam provides a very soft, point-elastic support for the head and neck area. The pillow is ergonomically shaped to fit the head and neck, gently supporting this area and helping to alleviate muscle tension. It is suitable for pillow covers measuring 40 x 80 cm or 80 x 80 cm when folded. The cover can be removed via a zipper, washed at up to 60 °C, and is dryer-safe. Outer cover: double fabric made of 61% polyester and 39% viscose with a blue satin trim and white side panels made of climate band.
