Casper Mattress Highlights

  • Casper is one of the early market leaders in the foam mattress space and offers a great universal mattress for the average sleeper.
  • This memory foam mattress promotes airflow, so you won’t get that hot, sinking feeling that you would with traditional memory foams.
  • Casper received a perfect score on responsiveness – meaning it does a great job of adjusting to your body positions as you move throughout the night. This is a great quality for combination sleepers!
  • The Casper team is continually refining its design based on customer feedback and sleep tests; so buying a Casper today doesn’t necessarily mean it’s the same one from a couple years ago. Casper’s latest innovation – Zoned Support – is a new foam system that contours high-pressure areas like your hips, shoulders, and core to provide relief and support where it’s needed most.
Purple mattress

Purple Mattress Highlights

  • The Purple is a mattress with a big personality, but it does have a lot to boast about: it sleeps cool, is great for spinal alignment and does a good job with reducing any movement you’ll feel from other people (or animals).
  • Customers who own the Purple have claimed it’s helped them relieve back and neck pains.
  • The Purple is topped with a unique pressure-releasing material that is especially great for back and side sleepers – when you lie on your back, it will help your spine maintain its natural curve and when you lie on your side, it will help keep your spine straight.

Summary

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 our 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 isolate, 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.

Customer FAQs

Which mattress costs more: Casper or Purple?

The Casper and Purple mattresses are very close in price. A queen size Purple costs $999 while a queen size Casper costs $995. Both Casper and Purple are known to run mattress sales around different holidays throughout the year.

Which mattress is better for side sleepers?

Both the Purple and Casper help keep your spine straight while sleeping on your side and cradle pressure points while filling in the other curves of your body so there’s no empty support. Both scored a 9.5 out of 10 for spine alignment in the side position. If you’re a side sleeper, you will likely find comfort on either of these mattresses.

Which mattress is better for back sleepers?

Purple and Casper both allow you to maintain the natural curvature of your spine while sleeping on your back, which eliminates any unwanted pressure and fills in the rest of your body space evenly. Based on our own testing, we’ve found that Purple does a slightly better job at this than the Casper.

Which mattress is better for stomach sleepers?

Sleeping on your stomach is not the best position to maintain healthy spinal alignment. Over time, you may experience some discomfort or lower back pain if you’re a stomach sleeper. However, if you’re stuck with sleeping on your stomach and looking at either the Purple or Casper, Casper will do a better job at allowing your body to sink in at the right spots and be supported where you need it most.

Which mattress is the best for back pain?

While both Purple and Casper customers have vouched for how each of these mattresses helped alleviate back pain, Purple’s pressure relieving top layer was specifically designed to cradle pressure points in the spaces you need them most. However, depending on your body type, weight and severity of your back pain, you may find more comfort in the memory foam feel of the Casper, versus the Purple’s hyperelastic polymer which is unique to Purple. Casper’s latest mattress version is also built with Zoned Support, which is also designed to relieve pressure around your hips and shoulders.

Which mattress has the best cooling properties?

While Casper’s top layers are meant to provide breathability and airflow while you sleep, they are still made with memory foam. We found that Purple’s top grid-like layer performs better at letting heat dissipate throughout the night, therefore keeping you cooler while you sleep.
