Does the mattress used on a baby bed need to fit tightly to the bed frame?

Yes, the mattress used in the baby bed needs to fit tightly with the bed frame. This is to ensure the safety of infants and provide a comfortable sleeping environment. The following are why it is very important for the mattress to fit tightly with the bed frame:
Prevent jamming: If there is a gap between the mattress and the bed frame, the baby's hands, feet, or a part of their body may get stuck in the gap, posing a risk of injury or suffocation.
Reducing the risk of suffocation: A tightly fitting mattress can prevent babies from pressing their faces into crevices while sleeping, thereby reducing the risk of suffocation.
Provide stability: The tightly fitting mattress will not move or slide as the baby moves on the bed, which helps maintain a stable and comfortable sleeping position for the baby.
Adhere to safety standards: baby beds and mattresses usually have specific size standards to ensure they fit tightly. Choosing a mattress that meets these standards can ensure the overall safety of the baby bed.
