Cribs, bassinets, and mattresses: check the whole setup

Make a small document pack

Save a readable photograph of the model label, the complete assembly manual, the manufacturer's contact information, and the mattress requirements. Keep these together rather than relying on a marketplace listing that may disappear. If an instruction refers to a numbered component, verify that component rather than substituting whatever fastener fits.

Check the CPSC recall database using the brand and model. For current sleep-space practices, consult CPSC safe-sleep guidance. Follow the exact product instructions for its parts, assembly, and mattress requirements.

Separate three decisions

Do not let conversion features make today's decision

A crib advertised as convertible may need separate parts for later configurations. Record what is included now, what would need to be obtained later, and which instructions describe the change. A future toddler-bed feature is not evidence that today's crib arrangement is suitable.

Similarly, advertised portability should prompt questions about the actual moving or folding procedure. Check the manual instead of assuming a product can be rolled with a child in it or moved between rooms without disassembly.

• Identify the exact model and read its instructions.
• Check recalls and obtain any required remedy before use.
• Verify all specified components without substitutions.
• Match the mattress requirements to the actual mattress.
• Check the final room location against current guidance.
• Keep conversion instructions and unused original parts identifiable.

Check items as you work through this list. These ticks reset on reload.

Before the first use

Have the person assembling the crib work through the complete manufacturer sequence, including its final checks. If there is damage, uncertainty about parts, or an unexplained gap, stop and ask the manufacturer. For a dimensioned planning sketch, use our nursery layout tool; it does not replace these checks.

Check the mattress as part of the product

Put the sleep-product instructions beside the proposed mattress information. Identify the required type and dimensions, and any manufacturer restrictions. A label such as “crib mattress” is a category description, not a promise that it belongs in every sleep product.

Do not use an extra mattress, folded bedding, or an improvised layer to solve a gap or make a surface softer. Ask the manufacturer about an unclear fit or missing supplied part before use. Save the answer with the model information so another caregiver does not repeat the same uncertainty.

For a bassinet, write down the transition triggers

A bassinet’s use limits belong to the exact model. Copy the manufacturer’s stated limits and developmental stop-use instructions into your record. Keep each one visible: a product can reach a use limit for a reason other than the weight number. Do not replace those instructions with a single age that applies to every baby.

The CPSC’s bassinet and cradle guidance explains the product category and regulatory requirements. For everyday sleep practices, use its current safe-sleep guidance, including a bare sleep space and placing the baby on their back. An equipment worksheet cannot assess your baby’s individual care needs.

Keep later configurations separate

If the product converts, label unused original parts and save the relevant instructions. Record what would need to be obtained for the future configuration. Do not use a drawing of a later stage as an assembly guide for the present stage, or assume that an accessory from a similar model is interchangeable.
