I’ve spent time digging into two popular dual-sided crib mattresses: the Letmxiu 5″ Crib Mattress and the Pawtong Crib Mattress with Cool Gel Memory Foam. Both are designed to grow with your child from infant to toddler, but they take very different approaches to support and comfort.
This comparison is for parents who want a mattress that works for both a newborn and a rambunctious toddler without buying two beds. The big question is whether you want a super firm, no-nonsense foam mattress (Letmxiu) or a more feature-packed hybrid with cooling gel (Pawtong). Let me break down what I found so you can make the right call.

Individual Product Breakdown
I looked closely at the construction, firmness, and real-world ratings for both mattresses to give you an honest take on how they actually perform for babies and toddlers.

The Letmxiu is a straightforward, no-fuss crib mattress that nails the basics. It’s made from a single layer of high-density foam that’s rated as Firm, which is exactly what you want for infant safety and suffocation prevention. I like that it has a massive 4.8 out of 5 stars from over 1,742 reviews and an Amazon’s Choice badge, so the crowd clearly trusts it. The downside is that with only one foam layer and no cooling tech, it won’t offer the plush comfort some toddlers might prefer on the softer side.
✅ Pros
- Ultra firm high-density foam meets federal safety standards (16-CFR-1633, 1632, 1241)
- Over 1,000 units bought in the past month with a 4.8 star rating
- Dual-sided design lets you flip every 2-3 months for even wear
- Cute Dinosaur Party and Dog & Rabbit print options available
❌ Cons
- Only one foam layer, so no hybrid or gel cooling features
- Cover is hand wash only, which is less convenient than a removable machine-washable cover

The Pawtong takes a more modern approach with a three-layer hybrid build that includes cool gel memory foam, standard memory foam, and high elasticity cotton. I appreciate that it has a removable outer cover made from ice silk and polyester, making cleanup much easier than the Letmxiu. The medium firmness rating is a trade-off — it’s more comfortable for toddlers on the softer side, but some parents might want a firmer surface for their newborn. It’s also a bit thinner at 4.5 inches compared to the Letmxiu’s 5 inches.
✅ Pros
- Three-layer construction with cool gel memory foam for temperature regulation
- Removable outer cover with ice silk fabric for easy cleaning
- Pocketed coil support adds structure that foam-only mattresses lack
- Fireproof and flame retardant treated cover for added safety
❌ Cons
- Medium firmness may not be firm enough for some parents of newborns
- Only 57 reviews at the time of writing, so the track record is shorter
- Thinner at 4.5 inches vs the Letmxiu’s 5 inches
Which One Should You Buy?
I’ve tested the specs and real-world feedback on both mattresses, and the right pick really comes down to whether you value ultra-firm safety standards or modern cooling features more. Let me break down who should grab which one.
Letmxiu 5″ Crib Mattress and Toddler Mattress is right for you if…
- You want the firmest possible support for a newborn and trust a mattress with over 1,700 reviews backing it up
- You prefer a simple, single-layer foam design that meets federal flammability standards without extra bells and whistles
- You want a fun printed design like Dinosaur Party or Dog & Rabbit to match your nursery theme
Pawtong Crib Mattress is right for you if…
- You want a hybrid mattress with cool gel memory foam and pocketed coils to help regulate your baby’s temperature
- You need a removable outer cover made from ice silk and polyester that you can actually take off and clean
- You prioritize a softer, medium-firm feel for your toddler over the rock-hard firmness of a foam-only mattress
❌ Who Should Skip All of These?
If you’re looking for an organic or natural crib mattress made from materials like organic cotton or wool, neither of these foam-based options is the right fit. You’d be better off checking out a brand like Naturepedic that specializes in non-toxic, plant-based construction.
For the vast majority of parents, I’d point you to the Letmxiu — it has a proven track record with over 1,700 ratings, it’s firm enough for infant safety, and it’s competitively priced. The Pawtong is a solid runner-up if you want the cooling gel and removable cover, but the Letmxiu is the safer bet for most families.
Frequently Asked Questions
Which mattress is firmer for a newborn: the Letmxiu or Pawtong?
The Letmxiu is significantly firmer. It’s made from a single layer of high-density foam and explicitly rated as Firm, which is the recommended firmness for infant sleep safety. The Pawtong is rated as Medium firmness because of its three-layer hybrid build with gel memory foam and cotton. If you’re buying for a newborn under 12 months, I’d go with the Letmxiu for the extra support.
Is the Pawtong worth it over the Letmxiu for the cooling gel memory foam?
It depends on your climate and whether your baby runs hot. The Pawtong has a three-layer combo of gel-particle memory foam, memory foam, and high elasticity cotton that’s designed to circulate air and transfer heat away from the body. The Letmxiu has no cooling features at all — it’s just plain high-density foam. If you live in a warm area or your toddler sweats a lot, the Pawtong is worth the extra consideration.
Which mattress is easier to clean: Letmxiu or Pawtong?
The Pawtong wins this one hands down. It has a removable outer cover made from ice silk and polyester that you can take off for cleaning. The Letmxiu’s cover is hand wash only and not removable, which makes spot cleaning a lot more annoying. If spills and messes are a regular thing in your house, the Pawtong is the smarter pick.
Which mattress has more reviews and a better track record?
The Letmxiu is the clear winner here with 1,742 reviews and a 4.8 out of 5 star rating, plus an Amazon’s Choice badge and over 1,000 units bought in the past month. The Pawtong only has 57 reviews at the time I’m writing this. If you want a mattress with a proven track record that thousands of parents have already tested, go with the Letmxiu.
Which mattress is thicker: Letmxiu or Pawtong?
The Letmxiu is 5 inches thick, while the Pawtong is 4.5 inches thick. That half-inch difference isn’t huge, but it does mean the Letmxiu offers a bit more overall material and support depth. Both will fit standard cribs and toddler beds just fine since they’re both 52 inches long by 27.6 inches wide.
Can I use either mattress for both an infant and a toddler?
Yes, both mattresses are dual-sided and designed to grow with your child from infant to toddler. The Letmxiu uses the same firm foam on both sides and recommends flipping or rotating every 2-3 months. The Pawtong has a firmer side for infants and a softer side for toddlers, which gives you two distinct comfort levels in one mattress.
My Final Verdict
The Letmxiu is my clear winner for most families. It’s firmer for infant safety, has over 1,742 reviews backing its quality, and offers that proven track record that’s hard to beat. The Pawtong is a great runner-up if you specifically want cooling gel memory foam and a removable cover, but the Letmxiu is the safer, more trusted choice at the same price point.
If you’re still on the fence, ask yourself this: do you want a mattress with thousands of happy parents vouching for it, or do you want the latest hybrid features? For me, the Letmxiu’s 4.8 star rating from 1,742 reviews and firm foam construction makes it the obvious pick for peace of mind.
