You just unrolled your brand-new play mat, set your baby down for tummy time, and watched the whole thing slide across the floor like a shuffleboard puck. Sound familiar? It's one of the most common frustrations we hear from parents, and it usually comes down to what's — or what isn't — underneath the mat. The right underlayment can transform a sliding, bunching play mat into a stable, secure surface. The wrong choice can actually make things worse. After testing dozens of combinations on every floor type, here's what we've found actually works.
Quick Answer
On hardwood and tile, use a thin non-slip rug pad (natural rubber, not PVC) or choose a mat with a built-in non-slip bottom. On carpet, most mats stay put without anything underneath. On laminate, a non-slip shelf liner works well. Never stack soft materials under a play mat — this creates an unstable surface that's unsafe for babies learning to balance.
By Floor Type: What Works Best
Hardwood Floors
Hardwood is the trickiest surface for play mat stability. The smooth finish that makes hardwood beautiful also makes it slippery.
Best option: Natural rubber rug pad. A thin (1/8 inch) natural rubber rug pad provides excellent grip without adding too much height or softness. Cut it slightly smaller than your mat so the edges don't stick out and create a tripping hazard. Brands like Gorilla Grip and RugPadUSA make affordable options.
Good option: Non-slip shelf liner. The rubberized mesh shelf liner sold at hardware stores (like Con-Tact Brand) works surprisingly well under play mats. It's thin, inexpensive, and easy to cut to size.
Avoid: Felt rug pads (they slide on hardwood), foam underlayment (too thick and unstable), and double-sided carpet tape (damages hardwood finish).
According to the Consumer Product Safety Commission (CPSC), play surfaces for children should be stable and non-shifting. A play mat that slides when a baby pushes off defeats the purpose of having a safe play surface.
Tile and Stone Floors
Tile floors are similar to hardwood but with one added consideration: grout lines.
Best option: Natural rubber rug pad. Same as hardwood — thin, grippy, and stable. The pad also bridges grout lines, creating a more even surface.
Good option: Yoga mat. A thin yoga mat underneath a play mat provides both grip and additional cushioning on cold, hard tile. This combination works well in kitchens and bathrooms where babies sometimes play.
Avoid: Anything thick or squishy. Tile floors need stability first, cushioning second.
Carpet
Good news — most play mats grip carpet naturally and don't need anything underneath.
When you might need help: Very low-pile or commercial-grade carpet can be slippery. In this case, a thin non-slip rug pad works. Also, if your carpet is very thick or plush, a play mat on top may feel unstable. In that case, the mat may actually be unnecessary — thick carpet already provides cushioning.
Laminate Floors
Laminate behaves like hardwood but is more sensitive to moisture damage.
Best option: Non-slip shelf liner. It won't trap moisture against the laminate surface the way rubber can.
Avoid: Rubber rug pads left in place for extended periods — they can cause discoloration on some laminate finishes. Lift and air out periodically.
What NOT to Put Under a Play Mat
Towels or blankets. They bunch up, creating an uneven surface. They also slide on hard floors, making the problem worse.
Multiple layers of foam. Stacking a play mat on top of yoga mats, foam tiles, or mattress toppers creates an excessively soft surface. The AAP recommends play surfaces that are firm enough for babies to push up and balance. Too-soft surfaces can actually delay motor development and pose suffocation risks for younger babies during tummy time.
Nothing on a slippery floor. If your mat slides and you just leave it, your baby will eventually ride it across the room. This isn't just inconvenient — it's a fall hazard when the mat shifts during pulling up or cruising.
What We Recommend
We designed Poco Koko play mats with a built-in silicone non-slip bottom specifically so you don't need to buy anything to put underneath. The silicone grips hardwood, tile, and laminate without leaving residue or damaging finishes.
That said, if you have an older play mat that slides, a thin natural rubber rug pad is the best universal solution. Pair it with any mat from our play mat collection or our crawling mats for the most secure setup.
