THANKO Once you try it, you'll be hooked! "Face-Down Sleeping Cushion Z" TK-PRC22B Purchased on Amazon on April 21, 2024. Used once, but it wasn't what I expected, so I stopped using it. I think it's in good condition. However, please understand that it is used. There is no box or instruction manual. Only the main unit. I will wrap it in bubble wrap and ship it. Shipping included.
