This is a Coco de Chica (Sandiesca) 3D fiber baby futon I just bought last month from the official website. I've been using it for newborns, both for nighttime and naps. It's easy to wash in the bathroom and dries quickly if it gets dirty. I bought it to expand by laying two of them side by side, but I have one extra because my baby hardly takes naps anymore, so I'm selling it. Price is firm. (Product Description Below) A baby mattress made with approximately 90% air 3D fiber, making it lightweight and highly breathable. - Size: 70 x 120 x 3 cm (standard size) - Material: 3D fiber - Brand: sandiesca I bought it for 6990 yen. Thank you for looking.
