Description

Technical Field

[0001] This utility model relates to the field of children's furniture, specifically a children's swivel dining chair. Background Technology

[0002] High chairs are essential tools for ensuring a baby's dining safety, cultivating good eating habits, promoting independence, and enhancing family interaction. Choosing a safe, comfortable, and functional high chair can make mealtimes more enjoyable for babies and make parenting easier for parents. Current high chairs consist of legs and a seat attached to the top of the legs. The seat cannot rotate relative to the legs. However, in daily use, parents often need to rotate the high chair, for example, during feeding. To make feeding easier, parents often need to rotate the entire chair so the child faces them. When a child is sitting in the high chair, rotating it requires effort due to the child's weight combined with the chair's weight. Currently, most high chairs on the market do not allow for easy rotation of the seat and legs. Utility Model Content
