The Chicco LullaGo is a compact, bassinet-style portable sleep space that has become a staple for new parents who need flexibility in tight quarters. Whether you have the LullaGo Anywhere (the travel version with its own carry bag) or the LullaGo Primo (the adjustable-height bedside bassinet), both models share one defining trait: they are substantially smaller than a standard playard.
That compact size is precisely the appeal. The LullaGo fits beside your bed, slides into a closet when guests visit, and travels in the trunk without eating up cargo space. But it also means your baby's awake time inside the bassinet happens on a thin, firm mattress pad that was engineered for safe sleep compliance, not for comfortable play. Parents frequently ask us whether a play mat really makes a difference in a space this small, and the answer is absolutely yes — even in a compact bassinet, the contrast between a thin firm pad and cushioned memory foam is immediately noticeable during tummy time.
For younger babies who spend waking hours in the LullaGo during the day, a properly fitted play mat can make tummy time and early movement practice meaningfully more comfortable.
Chicco LullaGo Interior Dimensions
| Model | Interior Length | Interior Width | Notes |
|---|---|---|---|
| LullaGo Anywhere | ~37" | ~21" | Travel bassinet with carry bag |
| LullaGo Primo | ~37" | ~21" | Bedside bassinet, adjustable leg height |
| LullaGo Portable Bassinet (older) | ~36" | ~20" | Slightly smaller; measure to confirm |
The LullaGo is significantly smaller than a standard Pack 'n Play (39" x 28"). Standard playard mats will be far too large.
At roughly 37 inches long by 21 inches wide, the LullaGo interior is narrow enough that off-the-shelf playard mats simply will not work. You need a mat cut specifically for a bassinet-sized space.
What Size Mat Do You Need?
A mat measuring approximately 36-37 inches long by 20-21 inches wide will fit cleanly. The LullaGo has rounded ends rather than squared-off corners, so a rectangular mat will leave small crescent-shaped gaps at each end. This is perfectly normal and does not affect the mat's performance across the usable surface.
When in doubt, go slightly smaller. A mat that is a quarter-inch too narrow sits flat and functions perfectly. A mat that is a quarter-inch too wide pushes against the bassinet walls and creates a raised, uneven surface.
What to Look For in a Chicco LullaGo Mat
Choosing a mat for a bassinet-style space comes with requirements that differ from a full-sized playard:
- Exact sizing is critical. The LullaGo interior is only 21 inches wide. Even half an inch of excess width will cause the mat to curl against the sides, creating ridges your baby can roll against. Always err on the side of slightly smaller.
- Keep thickness modest. The LullaGo has lower walls than a full playard. A very thick mat raises your baby closer to the top edge, reducing the effective containment height. Between 1 and 1.5 inches provides good cushioning without compromising the wall margin.
- Memory foam for the best comfort-to-weight ratio. In a bassinet built for portability, every ounce counts. Memory foam delivers better cushioning at a lower weight than comparable EVA foam alternatives.
- One-piece construction, always. In a compact space where your baby is within reach of every edge, puzzle tiles that can separate are an unacceptable risk. A single seamless mat is the only responsible choice for enclosed use.
- CertiPUR-US certification is essential. Your baby will spend tummy time with their face pressed directly into this surface, breathing inches from the foam. Certified foam has been independently tested for formaldehyde, phthalates, heavy metals, and volatile organic compounds. Read our full guide to non-toxic play mat materials →
- Wipeable surface for constant cleanup. Bassinets are ground zero for spit-up. A microsuede or leatherette cover lets you clean the surface in seconds without removing the mat from the bassinet.
As the Consumer Product Safety Commission (CPSC) emphasizes, any additional padding in a sleep or play space must fit snugly with no gaps, and only the manufacturer's original mattress should be used for sleep.
Our Recommendation
Poco Koko playpen mats feature 1.3-inch CertiPUR-US certified memory foam in a seamless one-piece design. Check our sizing options to find the closest match for your LullaGo model. The non-slip backing prevents the mat from shifting inside the bassinet, and the wipeable surface handles the steady stream of cleanup that comes with early infancy.

FAQ
Is the LullaGo big enough for a play mat to make a difference?
Yes. Even in a compact space, the contrast between a thin, firm mattress pad and a 1.3-inch memory foam mat is immediately noticeable during tummy time. Babies who resist tummy time on hard surfaces often tolerate it longer and more willingly on cushioned foam, and those early minutes of tummy time are important for neck and core development.
Can I use the play mat for sleep in the LullaGo?
No. The LullaGo is primarily a sleep space, and for sleep the AAP recommends only the original firm mattress. Use the play mat exclusively for supervised awake time. Remove it before every sleep period.
My baby is outgrowing the LullaGo. Is it worth buying a mat now?
A quality memory foam mat sized for a bassinet has a useful life well beyond the LullaGo. It can serve as a portable tummy time surface, a compact changing pad, or a cushioned mat for travel. The investment extends past a single piece of baby gear.
How do I know if a mat is too thick for the LullaGo?
If the mat raises your baby's head above the midpoint of the LullaGo's side walls during tummy time, it is too thick. For the LullaGo's relatively low profile, a 1 to 1.5-inch mat strikes the right balance of cushioning and safety margin.
