Using this baby changing station is easy. First, open the station with one hand using the damped gas spring. Hang your bag on the integral hook. Place your baby on the changing surface and secure them with the adjustable safety strap. When you're done, clean the HDPE surface with a mild cleaner. Remember, this station is designed for infants up to 3 1/2 years old and a maximum weight of 50 lbs (23 kg). Don't exceed this limit. For maintenance, regularly check the stainless steel parts for any signs of rust or damage. Wipe the Matte Black finish gently to keep it looking good.
