DescriptionCondition: 100% brand new and high qualityColor : BlueSize : 43cm*43cm / approx. 16.93 * 16.93 inMaximum bearing capacity: 110 kgPacking List: 1x air cushion, 1x pumpUsing Method1. Connect inflation tube to air tap, push against inner safety pad, then can be blown up or bled air2. Can use inflated ball, pump, inflator to blow up.Note1. Inflation requirement: inflating volume reaches 80% is suitable, which can extend service life. when inflated with a pneumatic pump, pay attention to pressure control, don`t exceed the maximum pressure.2. Wash with mild detergents to clean the air cushion direct surface to dry.3. Prevent sharp objects hurt airbags.4. Keep clean in dry and ventilated place after using up, pay attention to moisture.5. For locations has small temperature difference, the air cushion can be pumped directly, but it can be used after first inflation 8 hours later(better 12 hours)6. For locations has a big temperature difference such as winter, do not pump immediately, it should be placed in the temperate condition for 10 hours and the material become soft, then pump it, in case material become hard for low temperature and accidental damage under external force.7. It is a normal phenomenon inflatable products may be lax when inflated for the first time. As material of air chamber is a little elastic, it would become swollen and soft. Just blow up again will reach expected effect, don`t exceed the maximum pressure8. Any inflatable product (include tyre) would leak air naturally, it`s a normal phenomenon, please supply air timely
