How do you choose between three highly popular online mattress brands? Endy, Douglas, and Casper all have excellent reputations, but which one is right for you? You can’t test the beds out in the store, so you have to rely on your own research.

Mattress reviews are supposed to make this easier. But in practice, they often blur together. There are only so many ways to say "this bed is firm, but not too firm". And too many reviewers like to throw around technical jargon without explaining what it means.

We’ll review why each metric matters and how each mattress performs. And while we’re at it, we’ll tell you how the Hush mattress measures up.

Casper vs Douglas vs Endy: Breaking Down Three Popular Mattress Brands

Let's start with a big-picture look at what sets these three popular mattress brands apart.

Casper didn’t invent the idea of selling mattresses online, but they were among the first to boost it into a major trend. Customers loved how convenient it was to skip the showroom and shop for beds from home.

Our current round of mattress reviews will focus mostly on Casper's flagship all-foam bed. It’s the most comparable to the Endy and Douglas in terms of both construction and cost. The company has rolled out other beds, including some with a partial innerspring design. But all of them hit a noticeably higher price point.

The founders of Endy aimed to recreate Casper's success. In 2015, they rolled out their own version of the mattress-in-a-box, offering it at a competitive price point.

The Endy mattress avoided the body-conforming memory foam used by Casper and many of its copycats. Instead, the company patented a new open-cell foam, giving their beds more bounce and breathability. The Endy mattress also comes in just one signature style, making the buying process simpler.

The Douglas mattress debuted in 2017. It's one of several brands from sleep retailer GoodMorning.com. The Douglas is a highly affordable single-firmness mattress aimed at budget-conscious shoppers. It costs less than all the other models on our list.

The other big selling point of the Douglas mattress is eco-friendliness. For example, it incorporates lightweight, low-carbon materials to reduce fuel consumption. Douglas also uses recycled materials for packaging and renewable energy for manufacturing.

There’s one more option you should consider if you’re searching for a comfortable, durable, and affordable bed. That would be the Hush, our painstakingly engineered hybrid mattress. The Hush mattress combines responsive pocket coils with soft, heat-wicking foam to give you coolness and comfort in any sleep position.

Alright, we've met the contenders. Now it's time to see how they measure up.

#1: Support and Firmness

Support might be the most important thing about a mattress. Your bed needs to be firm enough to keep your body from sinking or sagging into awkward positions. It also needs enough give to relieve your body’s pressure points. How well do these three mattresses handle this balancing act?

How Supportive is the Endy Mattress?

The Endy is a medium-firm mattress, falling right in the middle of the pack. Its open-cell memory foam is pleasantly soft without giving you the "wrapped-up" feeling you get from conventional memory foam.

Most people will feel fairly well-supported when they lie down on the Endy. Plus-sized sleepers may not be so comfortable, though. This is pretty typical for a foam mattress. Those spongy inner layers aren't quite sturdy enough to hold up the hips and trunk of a heavier person. This can create an uncomfortable bend in your spine.

The support foam also tends to give way when you're near the edge. It can buckle under you, creating a feeling of sliding or sinking. If you put a high value on edge support, the Endy mattress might not be for you.

How Supportive is the Casper Mattress?

Foam mattresses tend to be very squishy. The Casper mattress is no exception, but it's on the firmer side for a bed without springs. It sports a thick core of high-density support foam, which does a good job holding up lightweight and average-weight sleepers.

The Casper also provides some "zoned support". That means there's denser padding underneath the hips and lower back. That's helpful because those areas hold the bulk of the body's weight. The zoned support keeps your core from sinking down and putting strain on your lower back. Casper outperforms both Douglas and Endy in this department.

As you might expect, this added firmness also gives the Casper mattress better edge support. You should be able to sleep or sit at the side of the bed without much trouble. You'll feel a bit of a dip - you can't get perfect edge support from a foam mattress - but less than you would with a Douglas or Endy mattress.

How Supportive is the Douglas Mattress?

The Douglas mattress has the most give out of all of the products we're comparing today. The top layer contains 2 inches of the company's EcoLight memory foam. This stuff hugs your body like ordinary memory foam, but it’s lighter and less carbon-intensive.

Whether or not that's a good thing will depend on your personal preference. Some sleepers love the way memory foam mattresses hug their body's curves. Others feel a bit smothered or trapped. Just be aware that you'll get more body contouring with the Douglas than the Casper or Endy mattresses.

Underneath the memory foam is Douglas's proprietary Elastex foam. This stuff mimics the feel of latex, adding some springy resistance in the middle of the bed. It helps keep your body from sagging too much, though again, you’ll sink deeper into the Douglas than you would into the other beds we’re looking at.

What about edge support? The Douglas bed is fairly middle-of-the-road in this area. It squishes less at the edges than the Endy mattress, but more than the Casper. You'll definitely feel a little unsteady when you’re all the way to one side.

However, if you want outstanding support no matter your body type, we recommend the Hush mattress. Our hybrid bed uses flexible springs in addition to foam, creating a strong support layer that can still compress to let you settle comfortably into place. And unlike the Douglas and Endy mattresses, the Hush offers zoned support for the heaviest parts of your body.

In fact, the Hush hybrid design is more in line with Casper’s high-end options. For example, Casper’s cheapest hybrid sells for $1695, more than twice the price of the Hush.

#2: Pressure Relief

No matter how firm you like your bed, you'll usually want a soft comfort layer at the top. This gives a little relief to the parts of your body that just out a bit more from your body.

Pressure relief is particularly crucial if you like to snooze on your side or your stomach. Side sleepers concentrate their weight on their shoulders and hips. And stomach sleepers often experience joint pain from pressure on their knees, elbows, and pelvis. Let's see how well our three mattresses relieve this strain.

How is the Pressure Relief on an Endy Mattress?

As we noted above, the Endy's comfort layer won't cup your body as much as memory foam. That decreases its pressure relief capacity a tiny bit compared to Casper or Douglas mattresses. On the other hand, the bouncier feel makes it easier to switch positions. You're less likely to get locked into an awkward pose all night.

Our main nitpick with the Endy's pressure point relief is that it doesn't hold up as well for heavier sleepers. The comfort layer is only 2 inches thick. If you weigh enough to flatten that out, your shoulders and hips could press on the stiffer support foam underneath. That may cause a bit of discomfort.

How is the Pressure Relief on a Casper Mattress?

Stomach and side sleepers with roughly average body weight should feel comfortable on the Casper. It's nearly identical to the Endy mattress in terms of pressure relief. The Casper bed is a little bit thicker, and its memory foam layer hugs your body a little more closely. But in practice, the differences are slight.

As with the Endy, though, heavier customers may notice pressure at their joints, hips, or shoulders. If you have a larger frame but you really want to go with a Casper mattress, you may be better off with their Wave Hybrid model. Again, it doesn't come cheap - you could buy four Hush hybrid mattresses for the same amount.

How is the Pressure Relief on a Douglas Mattress?

Douglas mattresses really shine in this category because of the lightweight foam at the top. This stuff nestles around your body’s curves and bony parts very nicely. That little bit of extra give puts it ahead of the Casper and Endy mattresses for pressure point relief.

Plus-sized people may still get some pushback when sleeping on their sides. The middle layer has a latex-like feel that offers a little more resistance to the dense polyfoam of the other two beds. But for average users, the Douglas mattress provides better pressure relief.

The Hush mattress also gives stellar pressure point relief in just about any sleeping position. The upper layer of the bed uses soft, breathable memory foam to cradle your body. And the springs underneath can flex to accommodate heavy sleepers without putting pressure on their shoulders and hips. It's great for side sleepers of any weight and stomach sleepers below 300 pounds.

#3: Motion Isolation

So far, we've mostly talked about solo sleepers. But what if you share your bed with a partner? Or you have kids who want to crawl under the covers whenever they have a nightmare? In that case, you want a steady bed that won't jostle you awake whenever your companion changes positions.

How Steady is the Endy Mattress?

If motion isolation is your top priority, you’ll love the Endy mattress. All-foam mattresses have a great reputation for staying still even if one sleeper is wriggling around. But the Endy is even better than the average foam bed.

And, of course, it's very quiet. There's nothing to creak or squeak as you move around. The Endy mattress won't make noise even if you have a very active nightlife.

How Steady is the Casper Mattress?

The Casper mattress is about average for a foam mattress when it comes to motion isolation. In other words, pretty darn good! Some customers felt that it has a little more wobble than the Endy, but most people likely won't notice the difference. It's a quiet, stable bed.

How Steady is the Douglas Mattress?

Douglas says the base layer of their bed is made of "motion isolation support foam". But we haven't seen anything to convince us that it's better at reducing motion transfer than an ordinary all-foam mattress.

That's not much of a criticism, though. The Douglas mattress still rates highly for motion isolation. And it's just as quiet as the previous two mattresses.

The Hush mattress is also great for motion isolation. That may come as a surprise if you’re used to standard innerspring mattresses. Old-school spring beds have their coils all linked together, so they pull on each other and shake the whole bed when they move.

But the coils in the Hush are in separate pockets, meaning one spring can get pushed down without tugging on the one next to it. This limits motion transfer so that your sleep isn't interrupted.

#4: Cooling

Temperature regulation is an important part of a good night's rest. Sleep scientists have found that getting overheated at night can interfere with both REM cycles and deep sleep. If you want to wake up feeling well-rested, you need a mattress that won't stifle you.

How Cool is the Endy Mattress?

As a general rule, it's harder to stay cool on foam mattresses. The spongy materials don't allow for much airflow. That means that the body heat you're giving off tends to get trapped very close to your skin.

The Endy is better than most foam beds. Its open-cell Comfort Foam lets more air through than normal memory foam. It also doesn't hug your body quite as closely. On top of that, the mattress cover is very lightweight and breathable.

Despite these helpful additions, the Endy mattress is still a big block of foam. If you run hot while you sleep, this bed won't give you much relief.

How Cool is the Casper Mattress?

Like the Endy, the Casper uses a fairly breathable foam for the top layer of their mattress. And Casper’s comfort layer has extra perforations to increase airflow. But as with the Endy, the middle foam layer is much thicker. This high-density memory foam contours to your frame, creating pockets where body heat can pool and build up.

This effect is reduced somewhat by the cooling gel that Casper places inside its memory foam. But even that can't completely cancel out the heating effect of sleeping on top of a giant sponge.

How Cool is the Douglas Mattress?

The Douglas mattress is about the same as the Casper for temperature regulation. The top layer is wrapped in moisture-wicking fabric to help get rid of sweat. And the comfort layer features a cooling gel foam called ecoLight.

Both factors help this mattress shed some heat. Sadly, they're offset by the thick, body-hugging foam. In terms of cooling power, the Douglas vs Endy vs Casper contest is a toss-up. None of them will do much to help hot sleepers.

We recommend the Hush mattress if you really want to sleep cool. Unlike the other three beds we're profiling, its hybrid build leaves a lot of open space for air to circulate. The comfort layer would normally be the hottest, but it's built with cooling gel foam, heat-wicking graphite, and a temperature-neutral phase-change coating. It feels as cool as the bottom side of the pillow.

#5: Customer Experience

Let's talk about what it's like to order a bed from one of these companies. After all, a bad buying experience can cancel out the convenience of shopping for a new mattress online. Here's what you can expect when you buy from these three brands.

Buying an Endy Mattress

When you buy from Endy, you get a 100-night sleep trial to see how you like the bed. Your purchase comes with a 10-year limited warranty, though that doesn't cover everyday wear and tear. All-foam beds like the Endy mattress typically last for 7-8 years of ordinary use.

Your rolled-up mattress will inflate on its own after you unwrap it. It should take around 3 minutes to reach full size. Endy recommends leaving the bed in a ventilated room for 24-48 hours to air out any lingering chemicals from the factory.

Buying a Casper Mattress

Casper gives you much more variety up front than the other brands we're discussing. Along with their flagship foam bed, they sell four other models, each one built for a specific type of sleeper. Like the Hush, these other mattresses are hybrids with both innerspring and foam components.

The downside is that Casper's products are the most expensive ones on this list. Their Original mattress only costs a little more than the Hush mattress, but their hybrids are significantly pricier. Note that Casper is the only US-based company on this list.

Casper gives you the same warranty and sleep trial as Endy. The unboxing, inflation, and off-gassing are roughly the same as well. And the materials should have roughly the same lifespan.

Buying a Douglas Mattress

Like Endy, Douglas sells a single medium-firm mattress, though theirs is even less expensive. They also offer the longest warranty (15 years) and sleep trial period (120 nights) out of any of the brands we're comparing.

Douglas also places a heavy emphasis on sustainability. Their factories are located in Canada and use 90% renewable energy. They package their beds in recycled materials, and their cooling gel foam has a lower carbon footprint than ordinary memory foam.

Unboxing and setting up your Douglas mattress is about the same as the process with the Endy and Casper beds. Again, you'll need to allow for a 1-2 day off-gassing period.

What if you go with Hush? We keep it simple, with one medium-firm mattress that will let almost anyone slumber in comfort. Like Casper, we give you a 100-night sleep trial to make sure you're satisfied. But unlike any of the others, our mattress is ready for use in minutes, with no off-gassing period required.

Douglas vs Endy vs Casper - Putting It All Together

Hopefully, you now have a better sense of the pros and cons of these three mattresses. Here's a quick summary:

The Douglas mattress will appeal to budget shoppers and those with a passion for sustainable consumption. It's also your best bet if you like an extra-soft mattress.

The Endy mattress is a good option for light and average weight sleepers who move around a lot while they snooze. Its motion isolation is above-average, and it doesn't hug you as tightly as a memory foam mattress.

The Casper Original mattress works well for those who like a slightly firmer bed with more edge support. And it's better for sleepers with back pain than the Douglas or the Endy.

Last but not least is our own Hush mattress, which serves up a fantastic blend of softness and support for a huge range of body sizes. It also gives you cooler sleep with top-notch edge support. Check out the Hush mattress for yourself and see why our customers love it!
