1. Wheels The material and size of the wheels are all considered. The rubber wheels are more durable and can be pinched by hand to see if the quality is good or bad. The large wheels have stronger shock absorption and stability, and are more suitable for baby use, while the small wheels are more light and convenient for travel. 2. Frame The aluminum alloy's frame is strong and lightweight and is the most suitable material. The material of stainless steel is very durable, but it is a bit heavy. The plastic material, although light but not solid, has a long service life. The smaller the baby, the better the quality of the selected vehicle. 3. Seat The seat thinness has little support for the baby's back and the baby can easily slide down when sitting inside. The seat is too soft and it is easy to trap the baby, which can also cause the spine to bend. Therefore, seats should be moderately soft and hard, and have protective facilities on the head and neck, or add a non-slip mat. 4. Safety belt Many people overlook the safety belt on the Stroller, but the seat belt is important for any car. When buying, be sure to choose a strong and easy-to-open seat belt that your baby can't open. The five-point seat belt fits perfectly with the baby's body and is thick enough to prevent the baby from sliding off the car. 5. Brakes A double-brake stroller is safer. When you step on your foot, you can stop the two wheels at the same time and unlock them simultaneously.
