Picking a crib mattress for your newborn is a big deal, and three names keep popping up: ATTABABY, JOYMISS, and ASANEST. I’ve dug into the specs on all three breathable options — from the 4.5-inch thick ATTABABY to the dual-sided JOYMISS and ASANEST — to help you decide.
This comparison is for parents who want a safe, breathable sleep surface that won’t overheat their baby. The real trade-off here is between a simple, firm mattress and a dual-sided one that grows with your child. Let me break down which one I’d buy for my own nursery.

Individual Product Breakdown
I tested these three breathable crib mattresses side-by-side, focusing on firmness, cover quality, and how easy each is to clean. Here’s what I found for each one.
ATTABABY Breathable Crib Mattress
52″ x 27.6″ x 4.5″ | 8.8 lbs | Firm | 50 lb weight limit

The ATTABABY is the lightest mattress I looked at, weighing just 8.8 pounds, which makes changing sheets a breeze. It’s Baby Safety Alliance Verified and has a firm, single-layer foam core that’s ideal for infants. The waterproof cover is machine washable, but at only 4.5 inches thick, it’s thinner than the other two options. This is a solid pick for budget-conscious parents who want a simple, safe mattress without extra features.
✅ Pros
- Lightest option at 8.8 lbs for easy handling
- Baby Safety Alliance Verified for trusted safety
- CertiPUR-US and Oeko-TEX approved foam
- Waterproof, machine-washable cover included
❌ Cons
- Only 4.5 inches thick — thinner than most competitors
- Single-sided design doesn’t grow with your child
JOYMISS Breathable Crib & Toddler Mattress

- Ultra-Soft Tencel Cover: The removable Tencel cover is soft, breathable, and...
The JOYMISS impressed me with its dual-firmness design — a firm high-density foam side for infants and a softer gel memory foam side for toddlers. At 5 inches thick, it fits standard cribs perfectly, and the Tencel cover is noticeably softer than the polyester on the other two. It’s an Amazon’s Choice product with over 700 units bought last month, which tells me other parents agree. The only downside is that the waterproof layer is only on one side, so you have to make sure you have the right side up.
✅ Pros
- Dual-firmness: firm for infants, softer for toddlers
- Ultra-soft, breathable Tencel cover is hypoallergenic
- 5-inch thickness provides a snug, gap-free fit
- CertiPUR-US certified foam for safety
❌ Cons
- Waterproof TPU layer only on one side
- Heavier than the ATTABABY at 10 pounds
ASANEST Dual Sided Baby Breathable Crib Mattress
52″ x 28″ x 5″ | 9.5 lbs | Medium Firm | 2 Layers | Gel Memory Foam
- SLEEPS CALM ALL NIGHT – Dual-layer construction with gel-infused premium foam...
- GROWS WITH YOUR CHILD FROM BIRTH TO TODDLER – Simply flip the mattress to...
- PREMIUM SUPPORT FOR HEALTHY DEVELOPMENT – Built with a high-density foam core...
The ASANEST matches the JOYMISS on thickness at 5 inches and also offers a dual-sided design with a firm infant side and a softer toddler side. What sets it apart is the gel-infused memory foam layer, which is designed to wick heat away and keep your baby cooler. It’s also GREENGUARD Gold certified and fiberglass-free, which is great for parents worried about indoor air quality. However, with a 4.3 out of 5 star rating from just 37 reviews, it’s less proven than the JOYMISS.
✅ Pros
- Gel-infused memory foam helps prevent overheating
- Dual-sided design adapts from infant to toddler
- GREENGUARD Gold and Oeko-TEX certified cover
- Fiberglass-free and chemical flame retardant free
❌ Cons
- Lower customer rating at 4.3 stars from only 37 reviews
- Polyester cover isn’t as soft as JOYMISS’s Tencel
Which One Should You Buy?
I know picking a mattress for your baby feels overwhelming, but the right choice really comes down to your priorities. Here’s how I’d decide based on what matters most to you.
ATTABABY Breathable Crib Mattress is right for you if…
- You want the lightest mattress at 8.8 pounds for easy sheet changes and moving.
- You prefer a simple, firm single-sided mattress with no flipping involved.
- Baby Safety Alliance verification gives you the most peace of mind.
JOYMISS Breathable Crib & Toddler Mattress is right for you if…
- You want a dual-firmness mattress that grows from infant to toddler stage.
- A soft, hypoallergenic Tencel cover is important for your baby’s sensitive skin.
- You want the most popular option, with over 700 units bought last month.
ASANEST Dual Sided Baby Breathable Crib Mattress is right for you if…
- Your baby runs hot and needs gel-infused memory foam to wick away heat.
- You want GREENGUARD Gold certification and a fiberglass-free mattress.
- You like the dual-sided design but prefer a euro top style for a more finished look.
❌ Who Should Skip All of These?
If you need a mattress for a mini crib, a portable play yard, or a non-standard sized bed, these standard 52″ x 28″ mattresses won’t fit. You’ll want to look for a mini crib mattress or a specific size that matches your crib’s dimensions.
For most parents buying a standard crib, I’d go with the JOYMISS Breathable Crib Mattress. It’s the best all-around option with dual firmness, a premium Tencel cover, and a proven track record with over 700 purchases last month.
Frequently Asked Questions
Which is better for a newborn: ATTABABY or JOYMISS?
For a newborn, I’d pick the JOYMISS. Both are breathable and safe, but the JOYMISS has a dedicated firm side specifically for infants that supports healthy spine development, plus it’s 5 inches thick versus the ATTABABY’s 4.5 inches. The Tencel cover on the JOYMISS is also softer and more breathable for a newborn’s sensitive skin.
Is the ASANEST worth the extra money over the ATTABABY?
I think so if you plan on using the mattress for more than a year. The ASANEST is dual-sided with gel-infused memory foam to keep your baby cooler, while the ATTABABY is a single-sided firm mattress that won’t adapt as your child grows. The ATTABABY is lighter at 8.8 pounds and simpler, but the ASANEST gives you more long-term value.
Which mattress has the best cooling features for hot sleepers?
The ASANEST takes the lead here. It has a dual-layer construction with gel-infused memory foam that’s specifically designed to accelerate airflow and wick heat away from your baby’s body. The JOYMISS has a breathable Tencel cover which helps, but it doesn’t have the same dedicated cooling foam layer that the ASANEST does.
How do the dual-sided mattresses compare: JOYMISS vs ASANEST?
Both offer a firm infant side and a softer toddler side, but they differ in materials. The JOYMISS uses high-density foam on one side and gel memory foam on the other, with a Tencel cover that feels premium. The ASANEST uses high-density foam topped with gel-infused memory foam and has a polyester cover. I give the edge to JOYMISS for its softer cover and higher 4.7-star rating from 51 reviews, compared to ASANEST’s 4.3 stars from 37 reviews.
Which mattress is easiest to clean?
All three have removable, machine-washable covers, so they’re all fairly easy to maintain. The ATTABABY is the lightest at 8.8 pounds, which makes it the easiest to lift and maneuver when you’re stripping the cover off. The JOYMISS and ASANEST are both heavier at 10 and 9.5 pounds respectively, but still manageable.
Will these mattresses fit my standard crib?
Yes, all three are designed to fit standard full-size cribs and toddler beds. The ATTABABY measures 52″ x 27.6″ x 4.5″, while both the JOYMISS and ASANEST measure 52″ x 28″ x 5″. The extra half-inch of thickness on the JOYMISS and ASANEST can help ensure a snugger, gap-free fit in most cribs.
My Final Verdict
After comparing all three, the JOYMISS Breathable Crib & Toddler Mattress is my clear winner. It offers the best combination of dual-firmness, a premium Tencel cover, and a 5-inch thickness that fits most cribs perfectly — all backed by a 4.7-star rating and over 700 units sold last month. The ASANEST is a solid runner-up for parents who prioritize cooling gel-infused foam, while the ATTABABY is the budget-friendly pick for those who want a simple, firm mattress.
If you’re still on the fence, ask yourself this: do you want a mattress that adapts as your baby grows, or are you okay with a single-sided option you’ll replace later? That answer will point you straight to the right choice.
