From the Britax Range, The Baby Safe Sleeper and The First Class.
The Baby Safe Sleeper is from birth to 10kg, and lies flat across two rear seats of a car. It is particularly useful for babies with very poor head control or perhaps hydrocephalus. Equally, babies with very weak necks or Restrictive Growth may benefit from lying rather than sitting until neck muscles improve.
The First Class is suitable for use from birth, and can be used rear or front facing, depending on the child’s weight. It offers a decent amount of recline and is again useful for those with poor head control. Both are usually available from stock for next day dispatch.
