Nitori Point-Supporting Mattress, double size. Comes with a cover. It folds into three for convenient storage and is ideal for apartments. I bought it new at a Nitori store about 4 years ago and used it on a tatami mat. I'm selling it due to moving. As it's a urethane mattress, it may have some sagging and fraying of the cover compared to when it was new. Therefore, I'm selling it at a bargain price. Please feel free to negotiate the price. I will use Rakuraku Mercari delivery for shipping, so it will be compressed for shipment.
