I've worn it a few times, but I'm selling it because my child has grown. Please refrain from purchasing if you are concerned as it is a used item. Here's the product description: Launched in 2020, Plaisiureux hip seats have sold over 50,000 units in total! (As of June 2022) Featured in the magazine "LDK Baby 1-Year-Old Parenting Goods." It was introduced in the hip seat section as "really good parenting goods," and its storage capacity, cost-effectiveness, and stability were highly praised. It is also used by current nursery school teachers and is recommended as a helpful item for childcare! [Product Overview] A hip seat that allows you to hold your baby simply by having them sit on the carrier (base) part. It's a waist belt type, making it easy for anyone to put on and take off. Compared to baby carriers with belts, it's easier to put the baby down and pick them up. It supports the baby's weight and reduces the burden on the shoulders and lower back of the user, such as parents. It's very useful for short outings, putting the baby to sleep at home, and various other situations. ● It's also very useful during times when you repeatedly pick up and put down your baby. [Product Specifications] Target age: 3 months to 36 months (after the baby can sit up) Size: Approximately 60cm to 115cm (The waist adjustment range has been improved to start from 60cm so that even slender people can wear it.)
