"The crib is where your child is going to sleep at night and you are leaving him," Sam himself is also a father. In an interview with the United States Good Morning, he said: "My child spends most of his time in a crib." That's why Delta's cribs are going to be rigorous in their company's confidential laboratory. Check to ensure safety per square inch. “We will shake each crib 72,000 times before and after to check for loose screws,†Sam said in an interview. “If one of the screws looses, it's a failure.†Each crib will undergo five tests before being sent to the store and nursery. First, check the mattress. The thickness and softness of the mattress are all taken into consideration. Make sure your baby is not injured. Second, check the screws. Be sure to ensure the tightness of each screw, even if the naughty baby in the bed to pick and go will not appear loose. Third, tap the experiment. Use a 30-pound hammer to knock the bed to see if it cracks. In case the baby's brother and sister climb into bed, the bed is broken. Fourth, check the railings. Tap the railing in a similar way to prevent loosening of larger people when leaning against the railing. Dongguan Aoxing Audio Visual Equipment CO.,Ltd , https://www.aoxing.net
