• Ergonomic Lie-flat from Day One
  Individual positioning – full lie-flat to upright. Healthy posture for the first 2 years. Outside the car, the Cloud S has an ergonomic full lie-flat position for strolling or carrying. Mounted on the Base S in the car, it provides a semi-reclined position, and a more upright position than previous models in the Cloud series. When reclining, the backrest and leg rest flatten simultaneously, spreading weight over a large surface. This reduces organ compression and helps prevent the head tipping forward.
