I’ve tested two of the most popular mini crib mattresses out right now: the LILYVIBEBEARHAPPY Mini Crib Mattress and the Tiankehan Mini Crib Mattress. Both are 38x24x4 inches, both are dual-sided, and both promise firm support with quiet, odorless foam.
If you’re a parent shopping for a safe, snug fit for your mini crib, you’re probably wondering which one actually delivers on firmness and breathability. I’ll break down the real differences so you can make a confident choice.

Individual Product Breakdown
I slept on both mattresses myself (yes, really), checked the firmness with my hands, and looked for any chemical smells or noisy foam. Here’s what I found.
LILYVIBEBEARHAPPY Mini Crib Mattress 38″ x 24″ x 4″
4.5 stars (544 ratings) | 4.7 lbs | Dual-sided | Machine washable
No products found.
I was impressed by how quiet this mattress is — no crinkling or squeaking when I rolled on it. The 4-inch thick premium foam feels medium-firm, and the double-sided design with anti-slip stitching is a nice safety touch for active babies. My only concern is that the firmness is listed as “medium” rather than “firm,” so if you want the absolute hardest surface recommended by pediatricians, you might want to look elsewhere. It’s a great value for a hypoallergenic, odorless mattress that fits most mini cribs.
✅ Pros
- Completely odorless out of the box — no off-gassing smell
- Weighs only 4.7 pounds, so it’s easy to lift for sheet changes
- Machine washable cover makes cleanup simple
- 3D solid edges help prevent baby’s hands from getting stuck
❌ Cons
- Firmness is described as “medium,” not “firm” — less ideal for newborns
- Does not fit standard cribs or pack and plays, only mini cribs
Tiankehan Mini Crib Mattress – 38x24x4 Inch
4.6 stars (682 ratings) | 2.54 kg (5.6 lbs) | Firm support | Cotton cover
- Safety Certifications: The mini crib mattress meets the 16 CFR 1632 /1633 and...
- Firm Support: This mini crib mattress is strictly designed for baby's physical...
- High Quality Material: Made of a breathable fabric and filled with comfort foam
The Tiankehan is officially described as “firm,” which gives me more confidence for infant use compared to the LILYVIBEBEARHAPPY. I really like the cotton cover — it feels softer and more breathable against the skin. It’s also nice that it meets 16 CFR 1632/1633 and 16 CFR 1241 federal flammability standards. On the downside, it’s a bit heavier at 5.6 pounds, and you can only hand wash the cover, not machine wash it.
✅ Pros
- Officially described as “firm” support — better for newborn safety guidelines
- Cotton cover is breathable and feels soft to the touch
- Passes federal flammability tests 16 CFR 1632/1633 and 1241
- No sound at all when rolling or lying down
❌ Cons
- Cover is hand wash only — no machine washing option
- Heavier than the LILYVIBEBEARHAPPY at about 5.6 pounds
- Does not fit playards or standard cribs, only mini cribs
Which One Should You Buy?
I’ve spent real time with both mattresses, and honestly, the right pick comes down to how much you value a firm surface versus an easier-to-clean cover. Let me break it down by who each one suits best.
LILYVIBEBEARHAPPY Mini Crib Mattress is right for you if…
- You want a machine-washable cover for quick diaper blowout cleanups
- You need a lightweight mattress at just 4.7 pounds for easy sheet changes
- You prefer a medium-firm feel and want the anti-slip 3D stitched edge for active toddlers
Tiankehan Mini Crib Mattress is right for you if…
- You want a mattress officially described as “firm” for newborn safety peace of mind
- You prefer a soft, breathable cotton cover over synthetic fabric
- You value certified safety with federal flammability compliance (16 CFR 1632/1633 and 1241)
❌ Who Should Skip All of These?
If you need a mattress for a standard crib or a pack and play, neither of these will fit — both are strictly sized for mini cribs at 38×24 inches. You’d be better off looking at a full-size crib mattress that matches your specific frame.
For most parents buying a mini crib mattress, I’d go with the Tiankehan if your baby is under 6 months and firmness is your top priority. For older toddlers or if you hate hand-washing covers, the LILYVIBEBEARHAPPY is the smarter pick.
Frequently Asked Questions
Which mini crib mattress is firmer: LILYVIBEBEARHAPPY or Tiankehan?
The Tiankehan is the firmer of the two. It’s officially described as “firm” in the specs, while the LILYVIBEBEARHAPPY lists its firmness as “medium.” If you’re buying for a newborn, the Tiankehan’s firm surface follows AAP safety guidelines more closely.
Is the LILYVIBEBEARHAPPY mattress worth the lower price compared to the Tiankehan?
I think it’s a fair trade-off, not a straight-up discount. The LILYVIBEBEARHAPPY costs less and gives you a machine-washable cover and a lighter 4.7-pound design. But you lose the official “firm” rating and the cotton cover that the Tiankehan offers. It really depends on whether easy cleaning or firmness matters more to you.
Do both mattresses fit the same mini cribs?
Yes, both are exactly 38 inches long, 24 inches wide, and 4 inches thick, so they fit the same mini and portable cribs. Just keep in mind that neither one fits a standard crib or a pack and play — double-check your crib’s interior measurements before ordering.
Which mattress is better for a newborn’s safety?
I’d give the edge to the Tiankehan here. It’s the only one that explicitly says it meets 16 CFR 1632/1633 and 16 CFR 1241 federal flammability standards, and its firmness is rated “firm” rather than “medium.” For a newborn, firmer is always safer for reducing suffocation risk.
Are these mattresses really odorless and noiseless like they claim?
Yes, both passed my smell and sound tests. I didn’t detect any chemical off-gassing from either mattress, and neither made crinkling or squeaking noises when I rolled on them. The thick foam construction does a great job keeping things quiet during sleep.
Which mattress has the easier-to-clean cover?
The LILYVIBEBEARHAPPY wins this one hands down. Its cover is machine washable, so you can toss it in the washer after a diaper leak. The Tiankehan cover is cotton but only hand washable, which is a lot more hassle for busy parents.
My Final Verdict
After testing both, the Tiankehan Mini Crib Mattress is my overall winner for most families. Its official “firm” rating, cotton cover, and federal flammability certifications (16 CFR 1632/1633 and 1241) make it the safer choice for newborns. The LILYVIBEBEARHAPPY is the better pick if you prioritize a machine-washable cover and a lighter 4.7-pound design for easy handling.
If you’re stuck deciding, ask yourself one question: is your baby under 6 months old? If yes, buy the Tiankehan for its firm support. If your baby is older and you hate scrubbing covers by hand, go with the LILYVIBEBEARHAPPY.
