This is the Minerva Mattress, which is a hot topic on YouTube (the online shopping version of Reiwa no Tora)! I've used it for about a month, but the firmness doesn't suit me, so I'm selling it! There are three small snag-like marks. Please check the images. I don't think it affects the use of the mattress. *Therefore, I'm selling it at a lower price. Since it won't fit in a box, I will roll it up and wrap it in bubble wrap for shipping. This product won second place in the online shopping version of Reiwa no Tora's overall sales ranking and has very good reviews and word-of-mouth. It's a "high-resilience mattress" that can be used in addition to your existing mattress or futon. It's designed to make it easy to turn over in bed, and is especially ideal for those who often feel tired in their lower back or back when they wake up. <Specifications> Single: Width 97 x Depth 195 x Thickness 3cm, 1.8kg <Materials> Minerva Foam® Density 35kg/㎥±2.8, Hardness 130N±23, Resilience 50%≦ Mattress Cover: 100% Polyester Original Price: 29,800 yen
