Best Crib Mattresses (2026), Our Top 5 Safe and Supportive Options

Our certified sleep science coaches and mattress testers often praise Saatva for crafting high-quality, durable, and comfortable mattresses for adults. The good news is that this level of quality also extends to Saatva’s baby gear, meaning your little ones can now enjoy the same support and durability thanks to the Saatva Crib Mattress. Product tester Riley Otis gave the Saatva a perfect 5 out of 5 in materials, firmness, and additional features, making it a clear winner for the title of best crib mattress.

According to Riley, the Saatva Crib Mattress uses top-notch materials that meet every criterion a parent could want. It also comes with a slew of certifications, including GREENGUARD Gold, OEKO-TEX Standard 100, and Cradle to Cradle Gold.

“Everything in this mattress is organic, natural, or recycled, which I think speaks to the overall quality of the product,” said Riley. “If I were a parent, the abundance of certifications would help give me peace of mind. This is an easy five stars for materials.”

During testing, Riley also praised the support of the Saatva Crib Mattress, giving it another 5 out of 5 score in our firmness category. Unlike many other crib mattresses, the Saatva is flippable and offers two firmness options. The softer side is meant to be more accommodating for toddlers. For this reason, Riley gave it another 5 out of 5 in the extra features category.

“This mattress is flippable, offering both a firm and an extra firm side,” Riley said. “The extra firm side is exceedingly firm, feeling close to a true 10 on our firmness scale. According to Saatva, the extra firm support is essential to have in infant mattresses to help prevent SIDS and sleep-related accidents. The reinforced edges should also keep the baby securely in the center of the mattress.”

The only category that did not get a 5-star score from Riley was value. The mattress costs $359 at full retail, which will likely be a bit steep for some parents. Riley gave it a 3 out of 5 in this category. Still, the number of certifications this mattress has and the overall quality of the materials justify the price.

If only the best will do for your baby, the Avocado Green Luxury Organic Crib Mattress is one way to ensure that your little one will lie in the lap of luxury. Our product expert gave this premium offering from Avocado a perfect 5-star score in three essential categories: materials, firmness, and size.

Avocado is known for producing organic, hypoallergenic, and durable mattresses and accessories. The Luxury Organic Crib Mattress is a worthy addition to Avocado’s canon (Avocanon?) and follows its tradition of using high-quality, all-organic components. Our product tester gave it a 5 out of 5 in the materials category, thanks to its many certifications that should offer parents peace of mind.

“This GOTS-certified mattress has some of the best materials I’ve seen in a crib mattress—definitely a gold star in this category,” our tester said.

The Avocado Luxury Organic Crib Mattress is flippable, meaning one side is slightly softer and can function as a toddler bed. Our tester gave this crib mattress another perfect score in this category, thanks to its ultra-supportive GOTS-certified foams. This level of support is essential for infants and young children because it helps prevent them from flipping off their backs during sleep.

“Both sides are safety-tested and labeled to meet infant firmness requirements for safety compliance,” our tester noted. “This means that even though one side is designed specifically to be a toddler mattress, both sides still pass all infant safety standards.”

Although you might not think about it, size is also a vital consideration. A crib mattress that is a corner-to-corner fit in your baby’s crib ensures that they have no space in between the mattress and the crib to roll into or get stuck in.

“I gave this crib mattress a 5-star score in the size category because there is no space between the crib and the mattress, almost to the point that it’s hard to lift the mattress to change the crib sheets,” our tester said. “However, I know this makes it super safe from a baby sleeping perspective.”

Quality and safety aside, the Avocado Luxury Organic Crib Mattress is not perfect. Our product tester gave it a 3 out of 5 in the price category because it is a steep $749 before any discounts. Additionally, both sides of the mattress have a label that reads “infant” on each, making it difficult to discern which side is for toddlers or 1-year-olds.

Many parents prefer organic bedding because it is typically hypoallergenic and made from thoroughly tested materials. The Emily Organic Crib Mattress by My Green Mattress is a prime example of a crib mattress in this category. Perhaps unsurprisingly, product expert Matt Schickling gave this crib mattress a 4 out of 5 or higher in our materials, firmness, and size categories during testing.

Like many other organic mattresses, the Emily Organic Crib Mattress earned a 5-star score during testing, thanks to its third-party certifications and soft feel.

“There is a nice list of certifications here, including GOTS, GOLS, Organic MadeSafe, and Greenguard Gold,” Matt said. “The mattress cover is soft to the touch and quilted of organic cotton and organic wool sewn underneath. It features an organic coconut pad made from organic coconut bound together with organic latex. It also has heavy-duty coil innerspring construction.”

According to Matt, the heavy-duty coil construction also lends itself to an ideal level of firmness and support for little ones, which he scored a 4.5 out of 5 during testing.

“It has very little give, and you should expect the baby to sleep more on top of the mattress than in,” Matt said. “You don’t have to worry about them sinking too far into the mattress and turning around.”

Similarly, Matt gave the Emily Organic Crib Mattress a near-perfect 4.5 out of 5 in the size category. According to him, you might be able to fit an adult finger between this and the spindles of a crib. This crib mattress provides a tight, secure fit, leaving no room for a baby to get between the mattress and the sides of the crib.

“One thing that’s unique about this is how firm the edges are,” Matt said. 

“The bed doesn’t have much give to begin with, and that is true right up to the edges. You do not have to worry about your baby sinking near the edge of this mattress. Among the firmest edge support I’ve seen in a crib mattress.”

The only real gripe that Matt had with the Emily Organic Crib Mattress is that it is not particularly stain-resistant. The brand highly recommends buying an organic mattress protector as a product add-on, which they sell for $62. However, he felt that it should be easier to clean in the event of accidents, spills, or soil.

Waterproofing and stain-resistance are two top concerns for many parents shopping for a new crib mattress, and understandably so. In the event of accidents, you want something easy to clean and care for. Thankfully, the waterproof cover on the Newton Baby Waterproof Crib Mattress lives up to its name, guarding against liquid in all its forms. Product tester Matt Schickling gave this crib mattress a perfect 5 out of 5 in the materials, firmness, and extra features categories.

Before feeling the softness of the materials, Matt was impressed by the third-party certifications and credentials listed on the Newton website.

“According to the brand, tests in a third-party CPSC-accredited laboratory showed that a baby gets 97% more air while breathing through a Newton Mattress than on a conventional waterproof crib mattress,” Matt said. “I feel comfortable knowing that this bed has undergone rigorous third-party testing for safe construction. You can tell that Newton balances quality products with safety, which is why I’m giving it a 5 in this category.”

Firmness was another category in which the Newton Waterproof Crib Mattress excelled during testing, earning a 5 out of 5 in this category.

“This bed is both firm and responsive,” Matt said. “It has just enough give to feel comfortable while providing adequate support.”

That said, the real star of the show is the mattress crib’s waterproof protector, which helped it earn a 5-star extra feature score. Matt praised its waterproof layer for two reasons: it actually works, and it is machine-washable.

“I tested the waterproof layer with a glass of water,” Matt said. “The waterproofing worked effectively when tested with liquids. I also love that the cover is removable and machine washable. You can also remove the core and wash it in your shower or outside with a hose with soap and cool water.”

The only complaint had more to do with customer service than the actual product. According to Matt, there is no clearly listed number to call to speak with a representative. They only offer email and chat. That said, he noted that you can easily resolve any issue with your product with a real human through those avenues.

Shoppers seeking the ideal balance between value and quality in their crib mattress should consider the Little Dreamer Crib Mattress by Moonlight Slumber. During testing, product expert Matt Schickling awarded the Little Dreamer Crib Mattress a 4 out of 5 or higher in materials, size, and value.

This USA-made crib comes GREENGUARD Gold-certified and features soft yet durable materials that impressed Matt during testing. He gave it a near-perfect 4.5 out of 5 in this category, docking half a point from the total score because he would have liked more details regarding the third-party testing.

However, the Little Dreamer Crib memory foam mattress more than made up for that half-point in the size category, which earned a 5 out of 5 during testing. 

“There is almost no space between the outer edges of this mattress and the inside of the crib,” Matt said. “The crib fits firmly in place and actually forms up to the spindles on the side. I wouldn’t be able to measure the distance with a tape measure because there was not enough space there to evaluate. You should feel totally comfortable with the fit of this.”

Another characteristic Matt appreciated about the Little Dreamer Crib Mattress was its price. Matt gave it a 4 out of 5 in this category because of its value relative to other high-end models.

“This is a good price for a decent quality mattress at $199.99,” Matt said. “It’s more affordable than higher-end models, but it does the job and is a solid pick for the price. No frills here.”

Aside from the lack of additional features and extras, Matt also noted that this crib mattress is a bit softer than some of its competitors due to its memory foam construction. He gave it 3.5 out of 5, citing that it might be a dealbreaker for parents seeking an ultra-supportive, extra-firm crib mattress for their little one.

“This is softer than the other two mattresses I tested because it is primarily made with foam,” Matt said. “It is a dual-sided mattress, so there is an “extra firm” baby side and a softer, plushier toddler side. Honestly, I think the baby’s side could be a little firmer. It is certainly firm enough, but if you’re very concerned with having a firm bed, I might skip this one and go for a model with innerspring coils in it.”
