Casper and Purple are two of the biggest names in the mattress industry. They both offer different sleep experiences with their mattresses and it’s no different with their signature pillows. Casper lends itself to the more traditional “fluffy” pillow route, while Purple is all about their patented Smart Comfort Grid.

How do these two pillows stack up, and which is going to be the right match? Check out my video comparison below or keep scrolling for more details. Don’t hesitate to comment below if any questions pop up!

Best Sleeping Positions For Each Pillow


Casper can work for all sleep positions

Based on my experience, I think Casper’s pillow can work with all sleep positions. Thanks to the pillow-in-a-pillow design, sleepers can take out the firmer inner pillow and stomach sleepers can use a single pillow, or back and/or side sleepers can combine the two pillows for a better fit.

I will mention 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.


Purple may be best for back and stomach sleepers

This pillow has a solid gel-like core and stands 3″ tall. Purple says their pillow will work for all sleep positions but that it’s especially popular for average-sized back and stomach sleepers.

I agree that it’s a better fit for average-sized back and stomach sleepers than side sleepers. I’m a combo back and side sleeper (and 5′ 7″ and average weight) and I felt that the pillow’s height and medium-firm feel made it the perfect fit when I slept on my back but didn’t like it as much on my side. When I moved to my stomach I was pretty comfortable, except that I didn’t care for the texture of the Smart Comfort Grid against my face. Aside from that, I think it’s a good height for stomach sleepers.

Larger body types will probably feel similarly about this pillow, it offers enough compression for both back and stomach sleeping without feeling neck strain, but there’s just not enough loft and height for side sleeping.


Casper’s signature pillow and Purple’s innovative pillow offer two very different sleep experiences. Customers will get that more traditional crisp and clean feel with the white cotton cover on Casper and its down-like softness in the filling. Meanwhile, the supportive but gel-like and squishy feel of Purple is less familiar but still very comfortable. Even Purple’s pillow cover offers a more performance wear-like feel that gives it a modern vibe.

Which one is best for each of us really comes down to sleep position and personal preference. Combo sleepers who end up in all positions may enjoy the versatility of the Casper. Tried and true back and stomach sleepers who haven’t found success with foam options may want to give Purple a try.
