This is a MOGU donut-shaped cushion. It's a calm khaki color that blends in with the interior. I bought it about two years ago and used it for a while. I'm giving it away because I no longer have the opportunity to use it. ■Size (Height x Width x Depth): Height 390 x Width 390 x Depth 80mm ■Weight: 290g ■Composition: Outer fabric: 85% nylon, 15% polyurethane / Filling: Powder beads (expanded polystyrene) ■Convenient and cute for various uses As a donut cushion, as a pillow, as a back support, as a frisbee? ... the MOGU circle cushion can be used in various situations! The circle cushion, which uses powder beads and spandex, fits perfectly to the area you want to support and wraps you in a soft touch. ■Uses high-quality, high-performance spandex fabric that stretches in all directions. This fabric uses fibers with excellent water absorption and quick-drying properties, which are also used in sportswear. That's why it feels moist, smooth, and comfortable. ■Independently developed powder beads (R) Only MOGU has a plant that can make these beads! Uses ultra-small polystyrene beads with a diameter of 0.5mm to 0.9mm. Because the beads are small, they are not easily crushed, so the cushion does not sag, and because they are ultra-small beads, the beads move freely inside the cushion, creating a chewy feel. MOGU's unique manufacturing method, developed for use as an interior item to be used directly on the body, leaves almost no harmful gases or the smell of styrofoam. Each bead is specially coated to reduce friction noise, so it achieves even smoother movement inside the cushion and does not produce unpleasant rustling sounds that are gentle on the ears. As a hip supporter, as a pillow, as a back support, as a frisbee? ... you can use it freely in the areas you want to support.
