Infant Bed/Baby Cot/Crib Size

what bed data-lazy-sizes are there

The standard American size for an infant bed is 71.1 cm wide by 133.5 cm long or 28 inches wide by 52 inches long.

This is the most common size for a standard infant bed. Other countries in Europe have the smallest infant bed measuring 23 inches wide by 47 inches long.

At this size, the bed is intended to cater for an infant of between 0 to 3 years of age. The infant bed has reinforcements with slats that are approximately 3 inches apart.

This prevents the baby’s head from being caught in between the mesh.

These reinforcements are also done to keep a baby put in the crib and, therefore, increase the child’s safety when sleeping.

Like a bassinette, a baby cot is significantly raised off the ground to keep bad odor or fumes away from the baby.

Did You Know?

Effective from June 1, 2010, the US Consumer Products Safety Commission banned the use of drop-side cribs and prompted millions of product recalls of such baby cots due to the many fatal hazards reported.

These accidents would happen when the infant bed wears out or when the drop side has a loose fitting.

The baby accidents on record so far include babies suffocating after getting trapped in between a partially detached drop side and strangulation incidences happening when the baby’s head gets caught in between the V-shape formed by a somewhat detached drop side crib.

However, in most countries, toddler beds differ very slightly from baby cots. Both the baby cot and toddler bed can accommodate the same mattress size.

Toddler beds are designed to ensure that the transition of the baby from the crib to the toddler bed does not disrupt the developmental milestones of the little one.

This transition usually occurs when the baby is between 2 years and three years of age.

Just like the infant bed, toddler beds are reinforced on all sides to keep the baby from falling off the bed. These beds also have removable bed rails. They help the toddler to learn how to get on and off the bed independently without falling or hurting himself or herself.

Additionally, toddler beds are much lower than the infant beds to allow for easy entry and exit.

The toddler bed sizes are ideal for children below the age of seven years, beyond which the child will have to shift to an ordinary single bed.
