I am selling this because I no longer use it. It can be used on a chair or on the floor. The table is also removable. It was very useful. Other notes: * We inspect the items, but they are kept at home. Regarding the condition, there may be oversights. Please refrain from purchasing if you are concerned about this. * We do not accept claims after a purchase, so please understand this before making a transaction. * Shipping will be via Yu-Yu Mercari or Raku-Raku Mercari. * Please forgive any wrinkles due to storage or packaging. Thank you for viewing.
