[Mini Size] Goodrave C-CORE 3D Baby W Baby Futon Mini Retail Price: ¥21,780 Perfectly fits the Aprica Coconeil Air Plus, so I used it as the mattress for that. When in use, I always had a mattress pad and sheets on top of this, and as far as I can see, there are no major stains. The original bag and instruction manual are not included. It has considerable thickness, so it's moderately soft and seems comfortable to sleep on. The entire surface is mesh, so it's well-ventilated, which was very good. The cover can be machine-washed, and the inside can also be washed with a shower, so you can use it cleanly. It will be shipped in wrapping cardboard.
