Before we jump into this Purple mattress vs. Casper mattress buying guide, let me just start by saying that both of these online mattress companies offer stellar shipping and return policies.

Both companies offer free shipping, and the beds arrive quickly in a surprisingly small box directly to your door.

On top of that, both Purple and Casper offer a 100-night risk-free trial. Yes, that means you can try out each of these mattresses for 99 nights and if you don’t like it, the company will come pick up the mattress free or charge.

In addition to that, both mattresses are backed by a 10-year warranty. So basically they are trying to make it as easy and convenient as possible for you to give their mattresses a try because they are confident you’ll love them. And it’s hard for us to disagree — both of these mattresses get high grades from us.

Purple mattress overview

Purple is a little lesser known than Casper, but they still make one heck of a mattress. What differentiates Purple from other mattress companies is the material they use for their top layer.

It really results in a pleasant, unique feel. The company was founded by two engineers, so they maintain a big emphasis on sleep science and actually have 15 patents on their cushioning technology.

Mattress construction & Purple mattress topper

Beneath the special topper is a 4-inch bottom layer and 3.5-inch middle layer of polyurethane foam. Now getting to the good stuff, their proprietary top layer is comprised of 2 inches of pressure-releasing Hyper-Elastic Polymer.

Now I’m not going to lie — I didn’t know what that originally was either. But basically its a big grid of tiny, gel-like squares that can brace, move, and compress depending on the pressure it feels.

The result is a unique feel that you don’t get with traditional memory foam mattresses. When you lie down, you can actually feel yourself moving those little squares around. It’s a little weird at first. But once you sleep on it for a few nights, you actually really start to enjoy the feel of it.

In addition, polymer material is generally cooler than latex or other traditional memory foams. The grid design of the polymer is also designed to improve the air flow of the mattress.

So the net result is an ultra-cool sleeping experience — you definitely don’t have to worry about waking up hot with this mattress. In fact, it might be the coolest mattress overall we tested behind Cocoon Chill by Sealy.

Purple mattress feel & comfort

So we already kind of touched on the feel of the mattress, but in terms of firmness, we give Purple a 4.5/10. It’s a little softer than Casper overall, but it still provides quite a bit of support.

The mattress also gets pretty solid grades from us in regards to point elasticity. I know, another confusing term here, but basically all that means is that the mattress is able to provide pressure relief for heavier parts of your body while the other parts of the mattress remain unchanged. Motion transfer is also pretty limited with Purple — no issues there.

We think Purple is one of the most innovative and unique mattresses out there for the fact that it can equally accommodate back, side, stomach, and combo sleepers.

Casper is great, but it is a medium mattress in terms of its feel. Purple can be both firm and soft. It’s supportive when you’re on your back — especially in the small of your back — and your stomach, but soft when you’re on your side.

It really is a truly unique experience, sleeping on a Purple mattress. Don’t get us wrong, Casper makes a fantastic bed, but Purple is just different.

It’s hard to pick a winner for side, back, stomach, and combo sleepers, as both beds are accommodative. If you’re open to a new style of mattress, Purple’s a good option. But if you want a similar feel to other memory foam mattresses, Casper is the go-to there.

Purple mattress price

Prices range from $749 for an XL Twin to $1,399 for a king. Don’t let that price scare you off though, the Purple mattresses have a very unique feel and you could very well end up spending more than that if you buy a mattress of equal quality in a traditional brick-n-mortar store.

Twin XL$799
Cal King$1,449

Occasionally, you can find a Purple mattress coupon or bundle though to ease the sting of the price tag — check to see if there’s a current Purple mattress promotion.

Not going to lie, at first I didn’t know what to make of Purple mattress. After lying on all those other memory foam mattresses, I couldn’t make up my mind how I felt about the sleeping experience.

But after a few nights, it really started to grow on me, and it ended becoming one of my favorite mattresses.

Casper mattress overview

Casper is probably the more well-known brand out of the two. And although they didn’t create the DTC mattress business model, they are often credited for bringing the industry to the forefront. They became a $100 million company in less than two years — that’s some crazy growth!

Casper bed construction

Like the majority of DTC mattress companies out there, the Casper mattress is composed of different foam layers. The bottom 5-inch layer is what gives the mattress its support. On top of that is Casper’s new Zoned Support foam.

This layer is split into thirds — the portions under your shoulders and legs are a tad softer for pressure relief, and the portion under your hips and lower back is a bit firmer for more support.

The third layer is a 1.5-inch layer of memory foam, which adds even more pressure relief. Topping it off is a layer of open-cell foam designed to keep you cool and provide a little bounce. Then combining all these layers is a woven cover that can also be unzipped and removed in order to clean it if necessary.

In terms of keeping you cool, Casper does do a good job but is trailing Purple in this regard — more on this below. Still I have no complaints in this department — my room is upstairs and can get quite hot in the summer, and I’ve never woken up drenched in sweat.

Firmness/comfort/motion transfer

When it comes to firmness, we give Casper a 4.75 to 5.75 out of 10, with 10 being like sleeping on a basement floor and 1 being like sinking into the mattress as if it were a 15-year-old pillow.

So obviously with a rating like that, we think Casper has a pretty nice balance between firmness and softness. It’s pretty nice to say the least — when you lie down on it you just want to take a nap.

It does compress quite a bit if you literally stand or sit in one particular place on the mattress. But once you spread out and disperse your weight, it does a good job of contouring to your body and providing the necessary support.

We think Casper is perfect for back, stomach, and sleepers as well as combo sleepers (people who rotate between the three positions at night). It’s soft enough to where you won’t get shoulder or hip pain if you sleep on your side. It’s firm enough to support you on your back and stomach.

And if you find yourself switching positions frequently at night, Casper is just fine for that as well. This is an accommodating mattress.

Also, motion transfer is extremely minimal with Casper. We put a beer on one end of the bed and rolled around next to it, and it barely even moved. So that means you won’t have to worry about waking up your partner if you toss and turn a lot.

Casper mattress price

Prices for Casper mattresses range from $595 for a twin to $1,295 for a king. So a little on the higher side compared to other DTC mattress companies like Tuft & Needle.

Also, sometimes you can find a Caper mattress coupon to knock an extra $50–$100 off the price tag. Right now, you can use code RIZKNOWS for $200 off the Casper mattress.

Twin XL$695
Cal King$1,295

All things considered, we really like Casper. Their mattresses are super comfortable and supportive, and they breathe enough to where you won’t sleep hot. We can see why the company went from zero to hero in less than two years.

Overall, you really can’t go wrong here — we think you’ll end up really enjoying sleeping on this mattress. And since it’s a good $100–$150 less than Purple, it gets the better value grade from us.
