Some beds are not suitable for younger children. There are several loft-style beds on the list that definitely fall in this category. Since every child is different, each child will be ready for this type of bed at a different time. The child needs to be both large enough to climb the ladder safely as well as mature enough to climb it safely. The earliest that most children would be ready for this is around 4 years old, but some children may need longer to grow and mature before being ready for a loft-style bed. You will need to use your best judgement for this as you know your child best.
