Are you working long hours at a desk/from home, spending too much time on the road, or just feeling exhausted from poor posture? Then treat yourself by simply turning your chair into the comfiest seat cushion ever and adapt your work/travel station to the most ergonomic setup ever! The back cushion comes with a viscoelastic memory foam interior and zippered outer cover. The open cell structure of the foam encourages airflow so keeps the hips at an ideal temperature. Quickly recovers to the original shape after use. When placed towards the back of the chair, its shape keeps you back in a pressure-free position. Produced from 100% polyester faux suede, the cover keeps the cushion in place and protects it from stains. Breathable. It keeps you cool in summer and hot in winter. The cover is machine washable on a cold water cycle. Tumble dry is not recommended. Thanks to its lightweight and spongy nature, you can take comfort to the next level where you want, at home, in a car, or at work. It can be considered a perfect gift idea for your grandparent, for your wife or husband who wants to feel comfy at the desk, for your mother, father, or for your girlfriend/boyfriend who wants to fix the posture. Please do not forget to check your chairs' width before purchasing.
