Hamax Siesta, Reclining Child Seat The Hamax Siesta is approved for children from 9 to 22kg or Approx. 1-5 years of age, and can tip 20 degrees backwards from the upright position, which is further than any other seats on the market. It is constructed so that the centre of gravity does not move too far backwards, & is the only reclining function on the market that really solve the problem when children fall asleep in the seat. This combined with the special shape of the backrest allowing the head to fall backwards even when the child is wearing a helmet. Siesta has a special practical patented safety belt. A double buckle system makes a easy fit. With only one hand you fasten the safety belt. The other hand is then free to support the bike for greater safety while fastening the belt.
