Step-by-step instructions and tips for assembling your Lolly Convertible Crib safely and efficiently, from unboxing to toddler bed conversion.
Congratulations on your new Lolly Convertible Crib! This beautiful, functional crib will grow with your child from infancy to toddler years and beyond. While assembly might seem daunting, with the right approach and a little patience, you'll have it set up in no time. This guide walks you through every step, from unboxing to final safety checks, so you can feel confident in the process.

Before you begin, it's important to note that the Lolly Convertible Crib is designed with safety and durability in mind. Always follow the manufacturer's instructions included in the box, and use the recommended hardware. If you're also using a Newton Baby crib mattress, ensure it fits snugly within the crib frame for optimal safety and comfort.
What You'll Need Before Starting
Before you dive in, gather all necessary tools and materials. Most convertible cribs, including the Lolly, come with the required Allen wrench and screws, but having a Phillips screwdriver and a rubber mallet on hand can make the job easier. Clear a large, clean area in the nursery to lay out all parts and hardware. This not only protects the crib's finish but also helps you keep track of every piece.
Take a moment to inventory all parts against the parts list in the manual. This includes the headboard, footboard, side rails, mattress support, and all screws, bolts, and cam locks. If anything is missing or damaged, contact customer service before proceeding. Also, check that you have the correct mattress size—the Lolly is designed to fit a standard full-size crib mattress like the Newton Original Crib Mattress.
- Lay out all parts on a soft surface to avoid scratches.
- Use a power drill with a low torque setting for faster assembly, but be careful not to over-tighten.
- Keep small hardware pieces in a bowl or tray to prevent them from rolling away.
Step-by-Step Assembly Process
Start by attaching the side rails to the headboard and footboard. Most convertible cribs use a cam lock system: insert the cam bolts into the pre-drilled holes on the side rails, then align them with the corresponding holes on the headboard and footboard. Tighten the cam locks with a screwdriver. Ensure all connections are snug but not overly tight, as you may need to make minor adjustments later.
Next, install the mattress support platform. The Lolly offers multiple height positions, so choose the highest setting for a newborn and lower it as your baby grows and begins to sit or stand. Secure the support with the provided screws or bolts, ensuring it is level and stable. Then, attach the front rail. This step is easier with a helper, as the rail needs to be aligned and secured without shifting.
Once the frame is fully assembled, do a final tightening of all screws and bolts. Check that every joint is secure and that there are no sharp edges or protruding hardware. Give the crib a gentle shake to ensure it doesn't wobble. Finally, place the mattress in the crib and check that the gap between the mattress and the crib sides is no more than two fingers wide.
- Use a damp cloth to wipe down the crib after assembly to remove any dust from shipping.
- If you need to move the crib later, always lift it—never drag it, as this can loosen joints.
- Keep the assembly manual in a safe place for future reference, especially for the toddler bed conversion.
Converting to a Toddler Bed
When your child is ready to transition out of the crib, the Lolly Convertible Crib easily converts into a toddler bed. This typically happens around age 2 or when your child climbs out of the crib. The conversion kit is included with the crib, so you won't need to purchase anything extra. Follow the manual's instructions to remove the front rail and attach the toddler bed guardrail.
The conversion process is straightforward, but it's a good idea to have a second person to help hold parts while you secure them. After conversion, double-check that all hardware is tight and that the guardrail is securely in place. The toddler bed uses a standard toddler mattress, which is slightly smaller than a crib mattress. If you're using a Newton Baby mattress, ensure it fits appropriately.
- Convert to a toddler bed only when your child is ready—usually between 18 months and 3 years.
- Use a bed rail on the open side to prevent falls.
- Consider placing the bed against a wall for extra security.
Safety Tips and Common Mistakes to Avoid
Safety is paramount when assembling any crib. Always use the hardware provided by the manufacturer—substituting with generic screws can compromise the crib's integrity. Avoid over-tightening screws, as this can strip the threads or crack the wood. Also, never skip the final stability check; a wobbly crib is a serious hazard.
Common mistakes include assembling on a hard floor without protection, which can scratch the wood, and losing small parts. To avoid these issues, work on a rug or blanket and keep hardware organized. If you have to pause assembly, store all parts and hardware in a safe place, out of reach of children. Remember, a properly assembled crib is essential for your baby's safety.
- Do not use any crib mattress that doesn't fit snugly—this is a suffocation risk.
- Periodically check and tighten hardware as your child grows.
- Never place the crib near windows with cords or blinds.
Assembling the Lolly Convertible Crib is a rewarding project that sets the stage for countless peaceful nights. By following these steps and safety tips, you'll ensure a secure and comfortable sleep environment for your little one.
