A portable booster seat is a small, lightweight seat designed to elevate young children to a safe height for dining at a table. It typically features a secure harness system to keep the child safely in place and can be easily attached to most standard chairs. These seats are ideal for families on the go, as they can be folded or disassembled for easy transport. Many portable booster seats are made from durable materials that are easy to clean, making them practical for everyday use. They often come with additional features, such as non-slip bases and adjustable straps, ensuring stability and safety during mealtime.
