This is an olive green rug carpet that can be used for both heating and cooling. The top is made of fluffy olive green flannel material, which is warm. The back is gray and made of a material that provides a cooling sensation on contact. It has been opened to take photos for size measurement, but it is new and unused. I received it as a bonus when I bought a large piece of furniture, but I am not using it, so I am selling it. Stored at home for one month. 185 cm x 185 cm Thank you for looking.
