The Mattress Nerd’s Take: The Casper Foam pillow is a firm, lofty pillow that works great for side and back sleepers. The breathable materials allow it to sleep cool for a pillow made entirely of foam. However, it may be too lofty for stomach sleepers and not moldable enough for combination sleepers.

Who It’s Good For

  • Side sleepers
  • Back sleepers
  • Hot sleepers who love foam

Who It’s Not Good For

  • Stomach sleepers
  • Those who want a cloud-like pillow
  • Those who prefer a moldable pillow

Video Review

If you’re more of a visual learner, join me as I break down everything you need to know about the Casper Foam pillow.

Look Inside 

The Casper Foam pillow has a very simple pillow design: a cover and foam. The cover is made with a blend of spandex and polyester, which is a super durable construction. Plus, the cover is safe to put in the washing machine.

When we get into the foam, we’re not surprised that this pillow uses Casper’s patented Airscape foam, which is essentially just polyurethane foam (similar to memory foam) with wide air holes poked through for maximum breathability. The foam is super supportive and firm, so your head should stay elevated all night long.

The pillow also comes in two height options: mid-loft (2” gusset) or low-loft (1.25” gusset). The height you choose should depend on your sleep position and body type, which we’ll cover in the next section.


Mattress Nerd Pillow Scores

The best way to see how a pillow performs, and if it’s performing at all, is to break each performance factor down into a numerical scoring system—hey, we are Nerds after all. We look at factors such as cooling, alignment, customer experience, and how it works for each sleeping position.

Cooling: 4/5

Though foam isn’t exactly the coolest material around, the Casper Foam pillow features a material called polyethylene, which is super cool to the touch. Casper also uses something they call Airscape foam: foam that has perforated holes to allow for airflow throughout the pillow.

Alignment: 4/5

Neck alignment is just as important as spinal alignment because it keeps you from waking up with kinks in your neck. The Casper pillow provides great pressure relief and alignment for side and back sleepers, but it’s just too lofty for stomach sleepers.

Adjustability: 1/5

This pillow has the flexibility of a hardback book. There isn’t too much molding and shaping you can do, nor are there many options for adjustability. It’s literally a rectangle of cushioning foam. But on their website, you can pick between the mid-loft version and the low-loft version, as well as a Standard size or King size.

For more moldable options, consider the Casper Down Pillow or the original Casper Pillow, which is a down alternative pillow.

Quality of Materials: 3/5

The foam in this pillow is hypoallergenic and CertiPUR-US certified, meaning the off-gassing levels are low, and you won’t find anything toxic or harmful to you in its construction. Casper is known for making high-quality products, so the only reason we deducted two points is that there aren’t eco-friendly materials in this pillow.

Care: 4/5

The cover of the Casper Foam pillow is completely removable and machine washable. This is great for those with allergies or people who want to extend the life of their pillow. Also, as a solid block of foam, you don’t need to fluff the pillow for it to keep its shape. We knocked a point off because some pillows are completely washer-friendly.

Customer Experience: 4/5

You have 30 nights to try out this pillow (the industry-standard is 100) and a one year warranty, which is on par with the other pillow warranties on the market. We found Casper’s customer service to be friendly, responsive, and helpful.

Total Score: 3.3/5

Side Sleeping

Side sleepers need a pillow to fill the gap between their head and neck while keeping the spine aligned. I say the mid-loft pillow is perfect for side sleepers. It’s firm enough to keep the head in alignment without any slight dipping. 

My only callout would be for side sleepers with broad shoulders. There is no high-loft version of the Casper Foam pillow. If this sounds like you, check out the best pillows for side sleepers to find loftier options.

Back Sleeping

The best pillow for back sleepers keeps the head in that perfect middle: it shouldn’t have your head doing a backbend, but it shouldn’t bring your chin to your chest either. As always, back sleepers win. It simply depends on your body type if you need a mid-loft or a low-loft.

Stomach Sleeping

As a stomach sleeper, I know that pillows are a delicate balance. Because of the harsh angle we turn our heads, the flatter the pillow, the better. Bad news guys, even the low-loft pillow is too high for us. This will lead to bad neck and spine alignment. I suggest you try out the Casper Original pillow or see our list of the best pillows for stomach sleepers.

Score for Side Sleepers Score for Stomach Sleepers Score for Back Sleepers
4/5 1/5 5/5



  • Breathable Materials: The Casper Foam pillow features Airscape foam and a breathable cover, which facilitates a lot of airflow to keep you from overheating.
  • Lofty: The loftiness and support of the Casper pillow mean it works well for back and side sleepers. Plus, there’s no fluffing necessary for the pillow to keep its shape.
  • Machine Washable Cover: The pillow cover is completely machine washable and dryable, which is great for people with allergies and those who don’t use a pillowcase.


  • No Flexibility: This pillow is a block of foam, so it isn’t easily flipped, folded, or molded.
  • Not For Most Stomach Sleepers: The loftiness of the Casper Foam pillow means it isn’t the best option for most stomach sleepers.
  • Firm Pillow: While this isn’t a con if you like a firm pillow, those who prefer a plush, cloud-like pillow won’t find what they’re looking for in the Casper Foam pillow.

Is the Casper Foam pillow safe?

Yes, the Casper foam pillow is safe. The foam inside is CertiPUR-US certified which is a fancy stamp of approval to say itu2019s not toxic or made with harmful materials. If youu2019re looking for something more green, check out our list of best latex pillows.

What Casper pillow is best for neck pain?

The best pillow for neck pain depends on your sleeping position. If you are a side sleeper, definitely go with the Casper Foam pillow. If youu2019re a stomach sleeper, Iu2019d choose the Casper Original pillow. If youu2019re a back sleeper, you have your pick of the litter.

How long does it take for the Casper Foam pillow to expand?

Once you open your pillow, it takes about an hour or so to expand to full size. It stays pretty flat until then. Iu2019d recommend letting it air out for a day or so to wait for the off-gassing smell to go away before lying down on it. Trust me.

The Nerd’s Final Take

The Casper Foam pillow will provide the best night’s sleep to hot sleepers who love foam, side sleepers, and back sleepers. Stomach sleepers may find it too lofty, and those who want a moldable pillow may think it’s too stiff. You get a 30-night sleep trial and a one year warranty when you buy this pillow.
