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.
  • 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.
Purple mattress

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.

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 your spine stay fairly straight while side sleeping and cradle pressure points. 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 keep your spine’s natural curvature while back sleeping, which relieves pressure and prevents back pain. 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?

Stomach sleeping is not the best position for your spinal alignment. This may cause lower back pain. 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.


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 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.
