Key Similarities
- Pressure Relief: The Casper, being a memory foam mattress, helps relieve pressure in areas like shoulders, core, and hips, and the Purple accomplishes the same thing with its top layer of hyper-elastic polymer.
- Edge Support: Both mattresses scored highly on our edge support test, meaning they are great for side sleepers and people with restless sleep partners.
- Firmness Level: The Casper and the Purple registered as medium-firm on our firmness scale, with the former coming in at 6/10 and the latter scoring a 6.5/10.
- Sleep Trial: Both mattress companies offer a 100-night trial, so you’ll have plenty of time to break in the bed before making a final decision.
Key Differences
- Price Point: While the difference in price isn’t staggering, the Casper is more affordable than the Purple, especially in king size.
- Sleep Positions: The Casper is a great option for stomach sleepers, back sleepers, and side sleepers. The Purple works very well for back and side sleepers, but not quite so much for stomach sleepers.
- Shipping: Casper offers free shipping and Purple does not.
Casper Mattress Review Highlights
- Casper is an early leader in the bed-in–a-box space and a universal memory foam mattress that works for all sleeping positions.
- We named Casper one of the best mattresses for side sleepers.
- The open-cell foam in the Casper mattress allows for ample airflow to keep hot sleepers cool.
- In our lab test, Casper scored perfectly in responsiveness, meaning as you move and adjust throughout the night, Casper moves with you.
- The Casper mattress offers zoned support that contours hips and shoulders but firmly lifts your middle, keeping your spine aligned.
- The Casper Wave Hybrid and Casper Element are two more great mattress options from Casper.
Purple Mattress Review Highlights
- Purple offers wonderful back pain and neck pain relief with its pressure relieving materials.
- The unique Purple grid keeps your spine perfectly aligned when sleeping on your side, but allows your spine to keep its natural curve when you lie on your back.
- The grid also allows for air to escape, keeping you cool, while the polyfoam adds motion isolation for couples who are prone to toss and turn.

Inside the Casper Original Mattress
Casper is made of three layers of memory foam to provide a breathable, responsive mattress that contours to your body yet still feels springy, so you never sink too far into the bed.
The bottom layer is constructed of high-density foam that provides the structure needed to keep you from sinking into the top two layers. The second layer has 3 zones of memory foam, so the mattress can be at once firm under your hips and lower back and soft under your shoulders. Lastly, the top layer uses an open-cell memory foam to keep too much heat from getting trapped in the mattress.
- Airscape™ Foam: The first layer of memory foam that uses open-cell technology to provide airflow.
- Zoned Support™: A 3-zone memory foam layer that is softer under your shoulders but firmer under your hips and lower back.
- Durable Bottom Layer: The third layer is made of high-density foam that keeps you from sinking too far and adds durability.
Inside the Purple Mattress
Purple is a hybrid mattress using a combination of a hyper-polymer grid and layers of foam. The pressure-releasing combination of foam and hyper-polymer results in a durable mattress that provides outstanding spinal alignment.
Like the Casper, the bottom layer of the Purple is a dense foam that effectively supports the softer layers above it. The next layer is a plush, but still dense foam that benefits combination sleepers by responding to the body’s movements throughout the night. On top of that, the Purple grid gives the mattress its contouring abilities and impressive pressure relief. On top of it all is the soft cover that promotes airflow and helps keep things cool through the night.
- SoftFlex Cover: This soft-knit mattress cover flexes with the Purple grid and adds breathability.
- Purple Grid: A specially designed hyper-polymer layer that flexes under your pressure points and keeps the spine aligned.
- Dual-Layered Comfort Foam: A responsive comfort layer of polyurethane foam that prevents motion transfer.
- Base Layer: A layer of high-density support foam.

Cooling
It’s no surprise that Purple beat out Casper in this category. Memory foam mattresses tend to be the worst mattresses for air flow since their dense layers trap heat more than, say, a hybrid mattress. The open cell structure of the Purple’s alternating foam layers, combined with the SoftFlex Cover, whip up the airflow that is necessary to keep sleepers from overheating.
Responsiveness
When it comes to responsiveness, the Casper absolutely ran away with it, scoring a perfect 10 out of 10. The high quality memory foam of the Casper adjusts wonderfully to your body as your position shifts throughout the night, making it far and away one of the best mattresses we’ve ever reviewed for combination sleepers.
The Purple scored a 7 on the responsiveness test – about average as far as this category goes. If you’re someone who likes to feel snug even as you toss and turn, the Casper definitely might be the right choice for you.
Spinal Alignment
The same contouring memory foam that scored the Casper a 10 on responsiveness also helped to nab it an impressive 9.5 on spinal alignment, making it a solid choice for those who suffer from back pain.
Not to be out done, the Purple also came in at a 9.5 in the spinal alignment category. The pressure-releasing nature of the comfort grid helps to maintain the natural curve of your spine, even if you sleep on your side.
Final Breakdown: Which Is the Best Mattress?
So who comes out on top when you compare Casper vs. Purple? There’s not an exactly clear victor since everyone’s sleeping preferences and needs differ – what works best for some may be a nightmare for others.
But that’s not very helpful for closing your shopping journey. So we can tell you what we know to be true based on the facts.
The Casper and Purple are both great mattresses, but generally the Casper outperforms the Purple when it comes down to motion isolation, edge support, and responsiveness. Purple compares by offering pretty exceptional pressure relief and spine alignment – but Casper’s performance in these categories is also on-par.
The main difference that may help you decide between the two lies in their materials. The Casper is an all-foam mattress whereas the Purple is a hybrid mix of hyper-elastic polymer and foam. Looking for an all-foam, cozy feel to hug your body? The Casper is best for you. Looking for a supportive mattress to help alleviate those morning aches and pains? Go for the Purple.
