Pillow Reviews: Casper Vs. Purple Plush – What’s The Big Difference?

We receive free products to review and participate in affiliate programs. See our disclosure page for more information.

I matched the Casper pillow and the Purple Plush pillow together for comparison because they’re super similar in many ways. That said, their differences should be highlighted before any purchases are made!

From the outside, these two pillows look like they’re cut from the same cloth. They offer soft and fluffy filling and can be adjusted so they’re firmer at times and softer at others. But there is more to each pillow than meets the eye.

Their big differences lie in their outer covers, the way you adjust them, and which sleep positions they’re the best fit for.

Best Sleeping Positions For Each Pillow

Casper

This pillow can work with all sleep positions. I say this because you can take out the firmer inner pillow and use it by itself if you’re a stomach sleeper, or combine the two pillows if you’re a back or side sleeper.

My only caveat is that larger people or those with broader shoulders who sleep on their side may find this pillow goes flat more frequently or isn’t 100% supportive enough.

Otherwise, I do think it would work for all sleep positions.

Purple Plush

Purple Plush holds its own on with support and loft, and I think it’s great for side sleepers and most back sleepers.

Even with both sides unzipped (when the pillow is at its softest), it might be too much for stomach sleepers who tend to need something softer.

Overall

Both pillows provide that soft and fluffy down-like feel. They’re easy to wash and can be adjusted to fit your preferred firmness and feel. So in that sense, they’re both great.

Which one you choose will ultimately come down to personal preference with the fabric cover and what sleep position you’re in most frequently. Stomach sleepers may slightly prefer the Casper over the Plush, and vice versa for side sleepers.
