This is a Miracool Mat from Lee Seisakusho. (This is not the soft Miracool Mat.) Size: 70cm x 120cm I purchased this to prevent bedsores and to combat heat buildup. I used to put a thin bath towel on top of it when using it. I used it for about 3-4 months and have kept it stored at home since then. The elastic bands have stretched because I attached it to a futon. There are only two elastic bands. I would like to give this to someone who needs it. I washed it in the washing machine before listing it. I used a laundry net, but some small debris may have gotten inside. Please be sure to use a laundry net when washing this mat. The following is from the Lee Seisakusho website description: A miraculous mat that prevents stuffiness, heat, and pain Excellent for temperature regulation and pressure distribution! • The material itself regulates temperature, making it comfortable. • Excellent cushioning makes it comfortable even on the floor. • Always dry and not stuffy • Highly absorbent, heat-absorbing, and quick-drying. • Easy to wash in the washing machine, so you can keep it clean. This is an "Outlast" temperature regulating material product. • When it's hot, it absorbs heat and quickly releases it to the outside. • When it's cold, it releases heat and keeps the body warm. 1cm thick 3D mesh structure Excellent pressure distribution, breathability, and quick-drying properties are expected to prevent bedsores. Please check the website for more details. I will fold it and send it in simple packaging. I may change the shipping method between Yu-Yu Mercari and Raku-Raku Mercari. Please let me know if you have a preference. Please purchase only if you understand.
