Before you compare pillows, compare your own sleeping habits. The best pillow on paper is the wrong one if it fights the way you lie down.
This breakdown walks through sleep position, size, materials, price and guarantees for MyPillow and the Casper Original Cooling Pillow. It closes with what the snoring research says, which is less than the ads imply.
Start With How You Sleep
Take this as general guidance, not a trial finding. Back sleepers tend to want a lower pillow, while side sleepers need extra loft to fill the space between ear and shoulder.
Stomach sleepers usually do best with something thin. If you switch positions at night, an adjustable pillow is easier to live with than a fixed one.
Size and Shape on Paper
Casper’s standard pillow measures 26 by 18 inches, stands 9 inches tall uncompressed, and has a 2-inch gusset. The king stretches to 34 inches long, according to Casper’s product page.
On Amazon, the MyPillow Classic queen is listed at 28 by 18.5 inches with a thickness near 7 inches. The listing also advertises an adjustable loft, so you set the final height.
What They Are Made Of
Casper blends cotton and TENCEL in equal shares for the cover, with a cooling coating on its underside. Inside, a soft core sits within a firmer outer layer, both filled with recycled down-alternative fiber.
The MyPillow Classic listing names a 100% cotton cover and machine-washable care. MyPillow describes its fill as position-adapting, which we could not confirm through independent testing.
Price and Guarantees
In October 2026, Amazon showed a MyPillow Classic standard at about $29.98 and a queen pair at about $54.98. Casper listed the standard at $99 and the king at $149.
Casper gives you 30 days to return an unused pillow, plus a limited warranty of one year. The MyPillow Classic listing cites 24 months of manufacturer coverage, and returns follow the seller’s rules.
Snoring: What Studies Say
One 22-person randomized trial saw fewer snores with a head-position-changing pillow once sleep apnea had been excluded. Another small trial found that a head-positioning pillow pushed the median snoring index from 218 down to 115 snore events hourly.
A 2024 systematic review treats positional therapy as reliable but built on small, short studies. Neither MyPillow nor Casper is designed that way, so expect comfort rather than a quiet bedroom.

A Brand With a Complicated Past
In a November 2016 California settlement, MyPillow agreed to $995,000 in penalties, and Consumer Reports says it admitted no wrongdoing. The deal also ended its use of the “official pillow” tag for the National Sleep Foundation.
According to Wikipedia’s MyPillow entry, the Better Business Bureau revoked the company’s accreditation in January 2017. None of that tells you how the pillow feels, but it is context for the marketing.
Which One Should You Choose?
- Pick MyPillow if price and an adjustable loft top your list.
- Pick Casper if you want a documented cooling cover and a clear 30-day return window.
- Pick neither if snoring is the main complaint, and try natural options first, like those in our natural snoring remedies guide.

Make the Decision on Your Terms
Match the pillow to your sleep position first and your budget second. Keep the receipt either way, because the best test is a week of real nights.
