When I joined the Insider Reviews team, I quickly learned that there are some products nearly all reporters and editors on this team rave about: Brooklinen sheets, Hydro Flask water bottles, Allbirds shoes. The Casper Original Pillow is one of those "hall of fame" items that multiple team members love.

It wasn't until I tested 22 different pillows for our best pillow guide that I got a chance to try this pillow out myself, and it didn't take me long to join in on the hype. Former Insider Reviews reporter and self-proclaimed picky sleeper David Slotnick hit the nail on the head when he described it as the "Goldilocks pillow [that gets it] just right."

It's not too firm or too soft and hits all the elements that make for a good pillow: it's simple, adjustable, and easy to clean.

Design and specs

The Casper pillow is available in two sizes: standard and king. I tested the standard version, but both pillows feature two-layer construction, which strikes a balance between firmness and softness. The inner pillow provides a foundation of firm support, while the outer pillow is soft and fluffy.

The pillow is filled with polyester microfiber and covered by cotton percale fabric, so it's hypoallergenic and stays cool throughout the night. It also has a gusset, or an extra piece of material that creates a side panel, which adds structure.

Finally, the pillow is easy to clean: just unzip the outer pillow, remove the inner pillow, and throw both in the washing machine. 

Sleeping on the Casper Original Pillow

The Casper pillow is fairly lofty, which is why it's a particularly good option for side sleepers who prefer the feel of a fluffy down or down-alternative pillow over a memory foam pillow. The gusset adds support and loft that side sleepers need to bridge the gap between their shoulders and the mattress, and the removeable inner pillow provides some adjustability if you find the pillow is a little too lofty. 

I slept on the Casper pillow for many nights and found it really comfortable for back and side sleeping. I love that it's a bit malleable, which makes it great for scooping, folding, and hugging. The only folks I wouldn't recommend this pillow for are stomach sleepers — It's too lofty for stomach sleeping. 

The bottom line

I'm not alone in my love for this pillow. Ellen Hoffman, Insider Reviews' former editor-in-chief, believes this pillow is "a really nice marriage of a regular down pillow and a memory foam pillow." And former senior reporter Connie Chen claimed in a previous review that this pillow "combines the best elements that everyone wants: simultaneously fluffy and firm, comfortable, and a breeze to maintain."

If you're still unsure, Casper offers a 30-day trial window for you to test out the pillow and see if it's right for you.
