This dimensional limitation directly influences infant safety and is inextricably linked to the broader definition of what constitutes a regulation-compliant infant bed sleeping surface. Exceeding this thickness can create a hazardous environment, potentially undermining the safety features designed into the crib structure.

One critical consequence of a sleeping pad exceeding the specified thickness is the reduction of the crib’s side rail height. Federal regulations mandate a minimum side rail height to prevent infants from climbing out and falling. If the sleeping pad is excessively thick, it effectively lowers the side rail height, increasing the risk of falls. For example, a sleeping pad that is 8 inches thick, rather than the mandated under 6 inches, reduces the protective barrier by 2 inches, potentially allowing a more mobile infant to climb over the rail. Furthermore, an excessively thick sleeping pad may compromise the secure fit within the crib frame, potentially causing the sides to bow outwards and create gaps.

In summary, the thickness restriction is a critical element within the overall safety standard. Adherence to this dimension is essential to maintaining the integrity of the crib’s safety features and preventing potential harm to the infant. The “Thickness: Under 6 inches” specification, therefore, is not an arbitrary measurement but rather a vital safety parameter intrinsic to the definition of a standard infant bed sleeping surface.

4. Corner Radius

This element is not merely aesthetic; rather, it serves to ensure a precise fit within the crib frame, mitigating potential safety risks. Sharp corners could pose a hazard, while improperly rounded corners might lead to gaps. The defined corner radius ensures the sleeping pad conforms precisely to the crib’s inner dimensions, thereby reducing the possibility of entrapment. For instance, a sleeping pad with a sharper corner than specified could damage the crib’s structure over time, or potentially create a catching point for bedding, while an under-defined corner might not reach the edges, leading to space. Therefore, specifying the corner radius is a key component to ensuring safety and standard conformance of the mattress.

The implementation of a specified corner radius directly impacts the manufacturing process. Manufacturers must adhere to precise measurements and tolerances to ensure consistency across all sleeping pads. This requirement necessitates specialized equipment and quality control procedures, adding complexity to the production process. Failure to adhere to the specified corner radius can result in product rejection or, more seriously, in products that fail to meet safety standards, resulting in product recalls or legal action. In practice, compliance ensures uniform construction across brands and models, facilitating the ease of selecting a properly fitting sleeping pad.

In conclusion, the seemingly minor detail of a “Specified” corner radius demonstrates the intricate nature of what defines a standard-sized infant bed sleeping surface. This aspect of the measurement directly contributes to infant safety by ensuring a secure fit, mitigating risks of entrapment, and facilitating consistent manufacturing practices. Overlooking such details would undermine the purpose of standardization, which is to provide a safe and predictable environment for infants.
