Purple vs. Casper

Buying a mattress online is easier than ever before and Purple and Casper are two brands leading the way. The companies and their products are quite different so browse this guide to see the Purple and Casper models, construction, and whether one is a good match for your sleep preferences.

Two engineer brothers founded Purple and began producing its revolutionary mattresses in 2016. The company now makes the Original Purple Mattress made of their patented grid stretch polymer and the New Purple Mattress which is a hybrid with pocket coils plus the patented Hyper-Elastic Polymer™ that gives Purple its name and distinctive sleep experience. It’s branded as a No Pressure™ mattress.

Casper launched in 2014 with one mattress designed to meet the needs of a wide swath of the buying market. They have since added two more to the product line and now sell the Casper original, a bargain version called The Essential, and a luxury model called The Wave. Casper is one of the largest online mattress companies and continues to impress customers with their offerings.

Purple vs. Casper Firmness

How firm a mattress feels is different with each sleeper. Heavier people interpret firmness much differently than lighter people and tend to prefer firmer beds. A bed with the right of amount of support for you will keep your spine aligned in a neutral, comfortable position.

The bedding industry rates mattresses on a scale from 1-10. Beds rated 1 are extremely soft, and those rated 10 are quite rigid. Most people will find comfort in the middle range of 5-7. Heavier people may need to go firmer and very light people a bit softer.

Mattress firmness is subjective and varies based on your personal preferences and sleep needs.

Casper Firmness

Very Soft (1)

The three Casper models all fall close to the middle of the firmness scale. The original Casper comes in at medium-firm, about 6.5. The basic Essential model rates close to 6.5 as well. The upgraded Wave is the least firm of the three at about 5.5-6 which is closer to medium.

Purple Firmness

Very Soft (3)

The original Purple rates about 6.5 on the industry scale which is medium-firm. The New Purple mattress comes in three firmness options. Purple.4 is soft (rated about 5), Purple.3 is medium (rated 6.5), and Purple.2 is firm (rated about 7).  

Purple vs. Casper Sleep Experience

Mattress performance is reflected in sleep experience and is determined by the quality of the materials in the support and comfort layers and how they work together. Firmness is a function of the support core. Softness comes from the comfort layer of the mattress.

Some of the elements of sleep experience include:

  1. Motion transfer is how well a mattress contains energy released as you move.
  2. Temperature is how a mattress retains or dissipates heat from your body as you sleep.
  3. Responsiveness is how fast a bed recovers to its original shape after pressure changes.
  4. Bounce is important for sex and is the bed’s elasticity when you move on it.
  5. Edge support is how securely you can sleep on the outer rim of the bed without tipping.
  6. Off-gassing is the release of fumes after you uncompress a mattress containing foam.

Here is a glimpse at the difference between Purple and Casper sleep experience.

Buy the Purple Mattress


  • Motion transfer: The New Purple is better at containing motion than the original, but all models should let you sleep undisturbed.
  • Temperature: All Purple mattress are excellent at dissipating heat. The open grid design ensures no heat is trapped around your body.  
  • Responsiveness: The patented polymers in the Purple grid are responsive and recover almost instantly as you move around on all models.
  • Bounce: The original and new Purple mattresses have excellent bounce and the hyper-elastic polymers make this an excellent bed for sexual activity.
  • Edge support: The original Purple doesn’t have great edge support but New Purple is better because of the coils and perimeter.
  • Off-gassing: Purple mattresses don’t off-gas because they use food-grade materials. When you first unpack it, there is a “new mattress” smell that fades fast.

  • Motion transfer: Casper’s three models all offer reasonable motion transfer. In order of performance, Wave is best, then original, and then Essential.  
  • Temperature: The Wave sleeps coolest of the three with the Essential least effective at cooling. Foam is a warmer material and hot sleepers should take note.
  • Responsiveness: All Casper models offer decent recovery, but The Wave is best with its premium materials over the original or Essential.
  • Bounce: Casper’s support and comfort layers work well together for good bounce for sex, and you won’t sink in so deeply that you can’t move around easily.
  • Edge support: The Essential is the worst of the three for edge support and foam is always problematic for edge support. The Wave and original are better in this regard.
  • Off-gassing: Casper only uses CertiPUR-US foams free of toxic chemicals. The Essential has the least aroma after unpacking than the other two, but the smell fades quickly with all models.

Value is a function of the benefit you get from something compared to what it costs. Investing in a durable mattress of high-quality materials will serve you better long-term. Cheaper beds must be replaced more often and can wind up costing more in the long-run.

The Casper and Purple beds are drastically different in design, sleep experience, and cost. Note that you can’t get the Purple mattress in a standard twin. Purple puts a lot of science behind their beds for optimal performance but at greater cost.

Casper is more affordable and for a very tight budget, The Essential is the cheapest. It’s well made but doesn’t have the features of the others we’ve examined here. It won’t last as long, but for now, might be a fit for some buyers.

The Purple original is an excellent value. Purple is well-reviewed, and buyers love them but the newer models are much costlier. The New Purple.2 is an excellent cross-section of high-tech features, durability, and value.
