18 independent air chambers: Each air strip is 11.5 cm (4.5 inches) wide, providing precise supportA/B/C three-group circulation system (6 air chambers per group), more advanced than the traditional A/B two-group designContinuous 12 air chamber support: 2 groups (12) are inflated at any time, dispersing body pressure more evenly Compared with traditional mode:A/B two-group mode: only 9 air chambers support at the same time → pressure concentrationA/B/C three-group mode: 12 air chambers support → pressure is reduced by 33%, significantly improving comfort Clinical benefitsReduce the risk of pressure sores: dynamic alternation reduces local continuous pressureImprove sleep quality: gentle wave-like changes, reduce turning interferenceAdaptive support: three groups of circulation ensure that body pressure is always evenly distributed
