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.
If a child is older than 8 years old or over 57 inches tall, they are not required by law to ride in a booster seat. Best practice however would be to keep children under 57 inches riding in a booster until they meet the height requirement, regardless of age.
