The name malachite derives from the Greek Moloche meaning mallow, because the stone is the same color as mallow leaves. Malachite is copper based, and has been crushed and used as pigments for thousands of years.
Booster seats are for children who have outgrown convertible or toddler seats. Booster seats are for children who are 4 to eight 8 old, weigh 40 to 80 pounds, and are less than 4 feet, 9 inches in height. You can use a booster seat until an adult seat belt correctly fits the child without use of the booster seat. Always use both the shoulder and lap belts with a booster seat.
Children no longer need to use a booster seat once seat belts fit them properly. Seat belts fit properly when the lap belt lays across the upper thighs (not the stomach) and the shoulder belt lays across the chest (not the neck). The recommended height for proper seat belt fit is 57 inches tall.
