Tanita Balance Cushion TS-959 Set of 2 Balance Cushion Air pump (with needle) Instruction manual Black Dimensions: Width 330 x Height 60 x Depth 330mm You can train just by sitting on a chair with this cushion. It can support a weight of 100kg, so you can use it with confidence. I have used it a few times after inflating it with air. I would like to sell it as a set of 2. Regarding shipping, since stacking the two boxes will result in a 100-size package, I will send one box and the other cushion (taken out of its box) together. Thank you for your understanding and cooperation. Also, if you purchase by December 16th, it's a campaign, so I will send both boxes together.
