Start by matching the bed size to the mattress you plan to use and the space you have. Kids’ car beds typically come in toddler, twin, or full sizes, and some designs convert between sizes.

• Toddler: A lower profile that pairs with a toddler-size mattress; helpful for a closer-to-the-floor setup.
• Twin: A common long-term option that fits a standard twin mattress, often easier to pair with bedding.
• Full: Offers a wider sleep area; be sure to confirm room layout and door clearance.
• Convertible: Some models shift from toddler to twin as needs change; confirm this in the product description.

Compare your room measurements with the bed’s listed dimensions on the item page, and review the “Compatible mattress” details before you buy.

Choose the mattress size that matches the bed’s listed size on the item page—toddler, twin, or full. Compatibility can vary by model, so it’s helpful to double-check the product’s interior sleep surface dimensions and any notes on recommended mattress thickness.

• Use a same-size mattress as specified for the bed frame.
• Review the recommended thickness so side rails and the head/footboard contours work as intended.
• See whether a box spring or foundation is needed; many platform-style frames use slats and do not require one.
• Compare your mattress’s exact measurements with the bed’s “Compatible mattress” guidance.

Following the size and thickness recommendations can help the mattress sit securely, but always rely on the item page specs for the best fit.

Assembly effort varies by model, but most kids’ car beds arrive with labeled parts and printed instructions. Planning your workspace and tools can make things smoother.

• Set up in an open area and protect finishes with a blanket or cardboard.
• Having a second adult can help with aligning panels and managing larger pieces.
• Common tools include a Phillips-head screwdriver; some beds may include an Allen key for specific bolts. A small rubber mallet can help gently seat joints.
• Sort hardware before starting, follow steps in order, and tighten bolts evenly. Recheck fasteners after initial use.

Look for the “Assembly required” note and the “What’s included” section on the item page so you can prep any extra tools ahead of delivery.

Storage features depend on the design. Some car-style beds incorporate integrated spaces, while others leave room beneath the frame.

• Built-in cubbies or a footboard compartment may function as a toy bin on certain models.
• Open underbed clearance (when present) can pair with low-profile storage bins.
• Convertible styles sometimes include a small storage area as part of the bed’s body.
• Check the listing’s photos and “Features” section for terms like “built-in storage,” “toy box,” or “footboard compartment.”

Capacities and measurements can differ widely, so compare product dimensions with the containers you plan to use. If storage is a priority, review the item page details closely before purchasing.

Replacement hardware, decorative caps, and decals are typically handled by the product’s manufacturer or the seller listed on the item page. That’s often the quickest path to exact-fit parts.

• Check the listing for “Warranty” or “Support” details to find contact information.
• Have your order number and the model name ready to speed up assistance.
• For issues like missing parts on arrival, contact Walmart Customer Care through your account.
• If eligible, the returns window shown on your order may allow exchanges.

Availability can vary by model and season, so reaching out early can help reduce delays. Keep packaging and instructions until setup is complete in case part numbers are needed.
