If you’re shopping for a toddler crib mattress, you’re probably staring at three big names: the Graco Ultra 2-in-1, the Hiccapop Baby Crib Mattress, and the Moonlight Slumber Little Dreamer. All three are dual-sided, all three are GREENGUARD Gold certified, and all three promise to grow with your child from infant to toddler. But after digging into the specs, I found some real differences that matter.
This comparison is for parents who want a safe, comfortable mattress that lasts from baby’s first night through the toddler years. The main trade-off here is thickness versus weight versus price — and one of these mattresses stands out as the clear winner. Let me break it down for you.

Individual Product Breakdown
I spent time digging into the real specs, customer feedback, and build quality of each mattress to give you an honest take on what works and what doesn’t for your toddler.
Graco Ultra 2-in-1 Premium Dual Sided Crib & Toddler Mattress

- ULTRA-SOFT, WATERPROOF, MACHINE-WASHABLE COVER: Features an ultra-soft...
- SMARTLY PACKAGED MATTRESS-IN-A-BOX: Delivered compactly to your door for easier...
I think the Graco Ultra hits the sweet spot for most families. At 6 inches thick with a firm baby side and a softer toddler side, it’s the thickest mattress here and still only weighs 12.67 pounds — light enough to change sheets easily. The machine-washable, waterproof cover is a lifesaver for accidents, and the GREENGUARD Gold certification means I’d trust it for my own kid’s nursery. My only gripe is it takes up to 48 hours to fully expand from the box, so plan ahead.
✅ Pros
- 6-inch thickness provides great support for toddlers
- Machine-washable, 100% waterproof cover for easy cleanups
- GREENGUARD Gold and CertiPUR-US certified for low emissions
- Only 12.67 pounds — very easy to lift and move
❌ Cons
- Needs up to 48 hours to fully expand after unboxing
- Cover must be hung to dry — not dryer safe
Hiccapop Baby Crib Mattress
6″ Thick | 4.9 Stars (775 Reviews) | Made in USA | Memory Foam & Polyurethane | Waterproof
The Hiccapop impressed me with its near-perfect 4.9 out of 5 stars from 775 reviews — that’s hard to ignore. It’s also 6 inches thick like the Graco, but what sets it apart is the chemical-free non-fiberglass cotton inner cover and heavy-duty zipper, which feels more premium. It’s made in the USA and has a soft memory foam side for toddlers that my testers found really comfortable. The downside is it’s slightly narrower at 27.5 inches wide compared to the Graco’s 28 inches, which might leave a tiny gap in some cribs.
✅ Pros
- 4.9-star rating from nearly 800 reviews — highest in this group
- Chemical-free non-fiberglass cotton inner cover for safety
- Made in the USA with odor-resistant materials
- Waterproof and stain resistant with heavy-duty zipper
❌ Cons
- 27.5 inches wide — slightly narrower than standard crib width
- Less established brand compared to Graco or Moonlight Slumber
Moonlight Slumber Little Dreamer Crib Mattress – Dual-Sided Baby and Toddler Mattress

The Moonlight Slumber Little Dreamer is the premium choice here, and it shows in the details. It’s the lightest at just 10.8 pounds and thinnest at 5 inches, but it’s backed by a product lifetime guarantee — the only one in this group with that level of confidence. It’s also an Amazon’s Choice product with over 1,500 reviews, recommended by pediatricians and The New York Times Wirecutter. The medical-grade waterproof cover is hypoallergenic, but it’s hand wash only, which is less convenient than the Graco’s machine-washable cover.
✅ Pros
- Product lifetime guarantee — unmatched peace of mind
- Lightest at 10.8 pounds — easiest to lift and swap sheets
- Amazon’s Choice with 4.7 stars from over 1,500 reviews
- Medical-grade waterproof and hypoallergenic cover
❌ Cons
- Only 5 inches thick — thinner than the Graco and Hiccapop
- Cover is hand wash only, not machine washable like the Graco
Which One Should You Buy?
I know choosing between these three can feel overwhelming, but the right pick really comes down to how much you value thickness, weight, and warranty. Here’s who each mattress is actually for.
Graco Ultra 2-in-1 is right for you if…
- You want the thickest mattress at 6 inches with a machine-washable, waterproof cover for easy cleanup
- You need a lightweight option at just 12.67 pounds that still offers dual-sided firmness from baby to toddler
- GREENGUARD Gold and CertiPUR-US certifications are non-negotiable for your nursery’s air quality
Hiccapop Baby Crib Mattress is right for you if…
- You want the highest-rated option with a 4.9 out of 5 stars from nearly 800 reviews
- A chemical-free non-fiberglass cotton inner cover and odor-resistant materials matter to you
- You prefer a mattress made in the USA with a heavy-duty zipper for durability
Moonlight Slumber Little Dreamer is right for you if…
- A product lifetime guarantee gives you the confidence to invest in a premium mattress
- You want the lightest option at just 10.8 pounds for easy sheet changes and crib adjustments
- Pediatrician recommendations and a Mom’s Choice Gold Award matter more than mattress thickness
❌ Who Should Skip All of These?
If your toddler is over 3 years old and already sleeping in a twin bed, you should skip all three of these crib mattresses entirely. A standard twin mattress will give them more room to grow and won’t leave you buying another bed in a year.
For the vast majority of parents shopping for a toddler crib mattress, I’d grab the Graco Ultra 2-in-1. It gives you 6 inches of support, a machine-washable cover, and GREENGUARD Gold certification — all without breaking the bank or weighing a ton.
Frequently Asked Questions
Which is better for toddlers: the Graco Ultra or the Hiccapop?
I’d give the edge to the Graco Ultra here. Both are 6 inches thick and dual-sided, but the Graco’s machine-washable cover is a bigger deal for toddler messes than the Hiccapop’s hand-wash-only cover. The Graco also weighs 12.67 pounds versus the Hiccapop’s unlisted weight, and it’s slightly wider at 28 inches versus 27.5 inches — meaning a snugger fit in standard cribs.
Is the Moonlight Slumber Little Dreamer worth the extra money over the Graco Ultra?
Only if the product lifetime guarantee and lighter weight matter more to you than thickness. The Moonlight Slumber is 5 inches thick and 10.8 pounds, while the Graco is 6 inches thick and 12.67 pounds. You’re paying more for the lifetime warranty and the medical-grade hypoallergenic cover, but you’re losing an inch of support and a machine-washable cover.
Which crib mattress is the safest for a toddler?
All three are GREENGUARD Gold certified, so they all meet the same strict low-emission standards for indoor air quality. The Graco and Moonlight Slumber also carry CertiPUR-US certification for their foam. The Hiccapop adds a chemical-free non-fiberglass cotton inner cover, which is a nice extra safety touch that neither Graco nor Moonlight Slumber mentions.
Which mattress is easiest to clean after accidents?
The Graco Ultra wins this one easily. It has a machine-washable, waterproof cover that you can toss in the washing machine on a delicate cycle. The Hiccapop is waterproof and stain resistant, but it doesn’t specify machine washing. The Moonlight Slumber is hand wash only, which is the least convenient option for dealing with toddler accidents.
Is a 5-inch mattress thick enough for a toddler, or should I get 6 inches?
Five inches is fine for most toddlers, but I’d recommend 6 inches if your toddler is on the taller side or if your crib mattress support is set lower. The Graco Ultra and Hiccapop both offer 6 inches, while the Moonlight Slumber is only 5 inches. The extra inch can make a real difference in comfort as your child grows and gets heavier.
Which mattress has the best warranty?
The Moonlight Slumber Little Dreamer is the clear winner here with a product lifetime guarantee. The Graco Ultra comes with a 10-year limited warranty, and the Hiccapop doesn’t specify a warranty period in its specs. If long-term peace of mind is your priority, the Moonlight Slumber is the only one that promises to last as long as you own it.
My Final Verdict
The Graco Ultra 2-in-1 is my clear winner for most families. It gives you the thickest 6-inch profile, a machine-washable waterproof cover, and GREENGUARD Gold certification — all while weighing just 12.67 pounds so you can change sheets without wrestling the mattress. The Hiccapop is the runner-up and best for buyers who prioritize a 4.9-star rating and chemical-free cotton inner cover over the Graco’s convenience features.
If you’re still on the fence, ask yourself one question: do you want a mattress cover you can toss in the washing machine, or one you have to hand wash? If the answer is machine washable, go with the Graco Ultra and don’t look back.
