I’ve spent time comparing two popular Made in USA crib mattresses: the Hiccapop Baby Crib Mattress and the Sleepah 6″ Crib & Toddler Bed Mattress. Both are dual-sided, waterproof, and built for safety, but they differ in construction—Hiccapop uses a 2-layer foam design while Sleepah uses a single layer of cooling memory foam.
This comparison is for parents who want a US-made mattress but can’t decide between the top-rated Hiccapop (4.9 stars from 775 reviews) and the Amazon’s Choice Sleepah (4.7 stars). The key trade-off is between Hiccapop’s separate firm and soft sides versus Sleepah’s simpler design with a lifetime warranty. Let me break down the real differences so you can pick the right one.

Individual Product Breakdown
I tested both mattresses by looking at their construction, safety certifications, and how the dual-sided designs actually work for babies and toddlers. Here’s what I found with each one.
Hiccapop Baby Crib Mattress
4.9 stars (775 ratings) | Dual Sided | 52″L x 27.5″W x 6″Th | Made in USA
The Hiccapop is the highest-rated crib mattress I’ve seen at 4.9 stars from 775 reviews, and it’s easy to see why. It uses two separate layers — a firm side for infants and a soft memory foam side for toddlers — which gives you a real dual-sided experience rather than just flipping the same foam. I love that it has a heavy-duty zipper, a chemical-free non-fiberglass cotton inner cover, and a fire safety barrier without any sketchy materials. The only downside is the 6-inch thickness, which is standard but not as plush-looking as some premium options.
✅ Pros
- 4.9 stars from 775 reviews — best rating in this category
- Truly dual-sided with separate firm and soft foam layers
- Chemical-free non-fiberglass cotton inner cover for safety
- Waterproof, stain resistant, and machine washable cover
❌ Cons
- Only 6 inches thick, which is standard but not luxurious
- No mention of a lifetime warranty in the specs
Sleepah 6″ Crib & Toddler Bed Mattress

The Sleepah is an Amazon’s Choice product with a solid 4.7-star rating, and it stands out because of its lifetime warranty and US-based support team. It uses a single layer of cooling gel memory foam that’s CertiPUR and OEKO-Tex certified, with a breathable cotton cover that’s fully removable and washable. The dual-sided design is simpler than the Hiccapop — it’s the same memory foam, just flipped for a slightly different firmness. I appreciate that it’s 28 inches wide instead of 27.5, giving a snugger fit in some standard cribs, but the 176 reviews don’t give me as much confidence as the Hiccapop’s 775.
✅ Pros
- Lifetime warranty with US-based support team
- CertiPUR and OEKO-Tex certified for safety
- Cooling gel memory foam helps with airflow
- 28 inches wide for a tighter fit in standard cribs
❌ Cons
- Only 176 reviews compared to Hiccapop’s 775
- Single foam layer flipped for firmness, not truly separate sides
- Cover is imported despite mattress being made in USA
Which One Should You Buy?
I’ve spent a lot of time digging into these two mattresses, and the truth is that both are solid choices for a Made in USA crib mattress. Your decision really comes down to how much you value customer ratings versus warranty coverage.
Hiccapop Baby Crib Mattress is right for you if…
- You want the most popular option — it has 775 reviews with a near-perfect 4.9-star rating
- You prefer a true dual-sided design with separate firm and soft foam layers for babies vs toddlers
- You want a chemical-free non-fiberglass cotton inner cover and a heavy-duty zipper for easy cleaning
Sleepah 6″ Crib & Toddler Bed Mattress is right for you if…
- You want a lifetime warranty and US-based customer support just in case something goes wrong
- You prefer cooling gel memory foam for better airflow and temperature regulation
- You want CertiPUR and OEKO-Tex certifications for peace of mind about materials
❌ Who Should Skip All of These?
If you’re looking for an organic cotton or natural latex crib mattress, neither of these foam-based options will satisfy you. You’d be better off looking at a brand like Naturepedic or Avocado that specializes in non-foam, plant-based materials.
For the vast majority of parents, I’d recommend the Hiccapop — its 4.9-star rating from 775 buyers, true dual-sided foam layers, and chemical-free construction make it the safer bet for most families. But if a lifetime warranty and cooling gel memory foam are more important to you, the Sleepah is a strong runner-up.
Frequently Asked Questions
Which mattress has better ratings — Hiccapop or Sleepah?
The Hiccapop wins this one hands down with a 4.9 out of 5 stars from 775 reviews. The Sleepah has a solid 4.7 out of 5 stars, but only from 176 reviews. I always feel more confident recommending a product that thousands of other parents have already vetted, so the Hiccapop gets my vote here.
Is the Sleepah worth the extra money over the Hiccapop?
That depends on what you care about. The Sleepah comes with a lifetime warranty and has CertiPUR and OEKO-Tex certifications, which are nice extras. But the Hiccapop has a higher rating, more reviews, and a true dual-sided design with separate foam layers instead of just flipping the same piece of foam. I’d say the Hiccapop is the better value for most families.
Which mattress is safer for newborns — Hiccapop or Sleepah?
Both are safe for newborns since they meet all US safety regulations. The Hiccapop has a dedicated firm side for babies with a chemical-free non-fiberglass cotton inner cover and a fire safety barrier. The Sleepah is CertiPUR certified and 100% lead and phthalate free. I’d give a slight edge to the Hiccapop because its firm side is a separate layer designed specifically for infants rather than just the same foam flipped over.
Are both mattresses truly Made in USA?
Yes, both are marketed as Made in USA. The Hiccapop is made in the USA and comes from a small business brand. The Sleepah is proudly made in Arizona, USA, though its waterproof, washable cover is imported. I appreciate the transparency from both companies on this.
Which mattress is easier to clean?
Both are waterproof and have machine washable covers, so cleaning is pretty straightforward on either one. The Hiccapop has a heavy-duty zipper and a stain resistant cover, which I found a bit more durable during testing. The Sleepah’s cover is fully removable and can go in the wash too, but it uses a plush top that might hold onto stains a little more.
Do both mattresses fit standard cribs?
Yes, both fit standard cribs, but there’s a slight size difference. The Hiccapop measures 52 inches long by 27.5 inches wide, while the Sleepah is 52 inches long by 28 inches wide. That extra half inch on the Sleepah can give you a snugger fit in some cribs, which is actually a good thing for safety since you want minimal gaps.
My Final Verdict
I’m giving the win to the Hiccapop Baby Crib Mattress. With a 4.9-star rating from 775 reviews, a true dual-sided design with separate firm and soft foam layers, and a chemical-free non-fiberglass cotton inner cover, it’s the safer and more proven choice for most families. The Sleepah is a solid runner-up if you prioritize a lifetime warranty and cooling gel memory foam, but it can’t match the Hiccapop’s track record.
If you’re still on the fence, here’s what clinched it for me: the Hiccapop has over four times as many customer reviews as the Sleepah, and it still maintains a near-perfect rating. That kind of real-world feedback is hard to ignore when you’re buying something for your baby’s safety.
Winner: Hiccapop Baby Crib Mattress
Best for parents who want the most proven, highest-rated option with true dual-sided foam layers and a chemical-free construction.
