Japanese traditional Tatami mat/Futon mattress, firm and comfortable/natural grass/foldable, easily collapsible, ideal for bed, meditation, yoga, zen room/Japanese tea room, 3.5 cm thick.

["The surface is made of 100% rush grass. The back is a non-woven fabric. Rush grass has a peculiar smell. Some people may feel the smell strongly, as there are individual differences.", "If you are concerned about the smell, you can shade it for a day in a well-ventilated place. I think whether it bothers you to some extent, although it does not completely disappear.", "It is very suitable for those who love sleeping on hard surfaces. Great for back problems or in a lounge room. If used for relaxation and you are not used to sleeping on a very firm surface, it may take you a few nights to get used to it.", "Folds easily. It folds for convenient storage and carrying it in and out of the closet or outdoors for its beauty is simple peasy. Please wipe along the seam with a dry cloth or soft cloth to remove dust powder before use, then clean the mat surface with the wet towel and dry in a well-ventilated place. Do not expose to the sun.", "Suitable for bed/ meditation room/ yoga/ zen room/ Japanese tea room"]
