Casper Pillow Review

Casper designers slept on over 60 different pillows before settling on a fill and design they couldn’t get enough of. The result was the original Casper Pillow, which we’re taking a closer look at in this pillow review. 

The Mattress Nerd’s Take: The pillow-on-pillow design of the Casper Original pillow accommodates most sleeping positions, but you can’t adjust the loft or fill level. For that reason, we don’t love it for the average stomach sleeper who needs a relatively flat pillow. However, it works well for back and side sleeping, and the breathable design keeps the pillow cool for hot sleepers. Overall, it has a plush, yet dense, feel that’s ideal for those who love the feathery lightness of down but want to avoid the cost. For better options, see the best pillows for stomach sleepers.

Casper introduced pillows to the brand’s line of high-quality sleep products in an effort to accompany the bed-in-a-box Casper foam mattress. The Casper original pillow has a down alternative fill that’s denser and more supportive in the inner core of the pillow and looser and plusher in the outer pillow. In this review, we’re going to break down how this pillow feels. You’ll also see FAQs and our lists of pros and cons.

What Makes the Casper Pillow Stand Out


  • Unique design: The Casper pillow has a pillow-in-pillow design that enables you to experience a dense, supportive pillow core and plush, cushioning outer layer.
  • Down alternative: The polyester microfiber fill that gives the Casper original pillow its bulk has the plush, airy feel of down without the financial or ecological expense.
  • Machine washable: Unlike latex or memory foam pillows, the cotton and polyester Casper pillow can be cleaned in your washer and machine-dried.
  • Balanced feel: This pillow is designed to provide a blend of both pressure relief and support.


  • Pricing: The Casper original pillow is a little pricier than your standard off-the-shelf pillow, but you can save $11 by buying a two-pack.
  • Requires fluffing: The polyester microfiber fill compresses under pressure, so Casper recommends fluffing the pillow daily to get the best night’s sleep.
  • Not adjustable: While you can choose between a standard and King size pillow, you can’t adjust the fill or loft level.

What is the Casper Pillow Made Of?

Outer Pillow

The outer pillow has a 100% Pima cotton cover with a percale weave. This is the same weave that hotels tend to use for bedding, and it has a soft, crisp, and breathable profile. The pillowcase has a 2” gusset that keeps the pillow at an even loft level. Inside the outer pillow cover, fluffy polyester microfiber fill creates a silky feel that’s almost liquid-like. It shifts around easily if you change sleeping positions at night.

Inner Pillow

The inner pillow has a polyester fabric lining and the same microfiber fill as the outer pillow; however, the fiber clusters in the inner pillow are crimped to increase their density. Casper says each fiber is blown into the pillow individually, which makes the fill more resistant to clumping. The inner pillow can be removed from the outer pillow if you unzip the zipper on the side of the outer pillowcase.

What does the Casper Pillow Feel Like?

The Casper pillow doesn’t incorporate distinct cooling features, but the pillow-in-pillow design improves airflow, and it has a soft, woven pillowcase that feels cool to touch. Overall, the pillow has enough breathability to avoid the heat retention that can interrupt the quality of your sleep. 

The included pillowcase fits loosely enough to allow your head to sink down into the bulk of the pillow, but it doesn’t shift when you change your sleep position. You’ll sink down through the outer pillow—with its longer, smoother polyester fibers—and be gently cushioned by the firmer inner pillow, which has crimped fibers to enhance density and neck support

There is a 2” gusset around the perimeter of the pillow, but as a whole, the pillow is much loftier than 2” when fluffed up. The purpose of the gusset is to keep the fill evenly distributed and improve neck alignment. Casper even calls it the “backbone” of the pillow’s construction. While the gusset keeps the pillow a consistent height from side to side, the fill will require a quick fluff in between sleeps.

This pillow has a medium-soft firmness level that’s well-suited to most sleeping positions. Back sleepers will sink down through the silky, longer fibers of the outer layer and rest against the inner layer. The fill level isn’t adjustable, but side sleepers can bunch up or fold the pillow to get the right height for their frame. 

In general, we think this pillow works best for back sleeping and side sleeping, though stomach sleepers with larger body types may be able to find comfort on a pillow with a higher loft level.

Casper Pillow FAQs

Can I sleep on just the inner or outer pillow?

Technically yes, but Casper doesn’t recommend it. Casper designed the inner and outer pillows to work in tandem. There’s a good chance that the outer pillow will feel floppy and almost too flat without the inner pillow, so it’s best to keep both parts of the pillow together.

How do I clean the Casper pillow?

Just unzip the outer pillow, remove the inner pillow, and pop both in the washing machine. Use cold water and a mild detergent on the gentle cycle, and run the rinse cycle on your washing machine twice. Then, tumble dry on low heat with dryer balls or clean tennis balls.

How long does the Casper pillow last?

Casper recommends replacing your pillow every one to three years, but really, you should replace your pillow when you stop feeling supported by it or if it starts causing neck pain. Even though the Casper is a durable pillow backed by a warranty, remember to listen to your body.

The Nerd’s Final Take 

No pillow is one-size-fits-all, but the Casper pillow comes pretty darn close. Both sides of the pillow stay cool, thanks to a breathable cotton cover and airy fill. The pillow-on-pillow design provides plenty of neck support without straining your head too far up or down.

As is, the pillow is ideal for back sleeping, since it provides a seamless blend of support and fluffy, cloud-like cushion. It’s also lofty enough for the average side sleeper, though you may need to bunch it or fold it in half to get the right amount of height. Stomach sleepers can do their best to flatten the pillow out, but unless they have a larger body type, a thinner pillow is probably their best bet. 

Casper sleep products are known for their balanced comfort and competitive durability. With 30 nights to give this unique pillow a shot, we think it’s worth trying.
