Purchased new in 2017. Used for raising two children. Please check the second photo for stains. I think the frequency of use was relatively low. The main body isn't worn out and still retains its firmness. However, the rubber band used to secure the adjustment belt has stretched, so I dealt with it by doubling it over or tying the adjustment belt itself... Shipping via Yamato Transport is expected to be 850 yen. Shipping will generally be on weekends, but please comment if you need it sooner, such as with Yu-Yu Mercari Delivery.
