Casper is one of the biggest names in the online mattress industry, while Allswell, a Walmart brand, has quietly made a name for itself by offering excellent beds at affordable prices.

Both brands offer hybrid mattresses — the Casper Hybrid and the Allswell Supreme.

Both mattresses are outstanding solutions, but the Supreme is better suited for couples while the Casper Hybrid is preferable for individuals, as well as side sleepers who tend to overheat.

One common misconception about bed-in-a-box mattresses is that you can only order all-foam models. Many believe that if you want a bed with innersprings, you have to head to a local brick-and-mortar showroom, where a salesman will deliver his high-pressure spiel to you. This simply isn't true.

Hybrid mattresses are an increasingly popular online solution. Made with a combination of innersprings and another material, typically foam, hybrid beds are available from all of the top bed-in-a-box brands.

Casper has two hybrid mattresses: the Casper Hybrid and the Wave Hybrid. The Wave costs about twice as much as the original hybrid, and I have not personally tested it. Allswell also has two hybrids: the Luxe and the Supreme. The Luxe costs much less than the Supreme and is a great choice, though I prefer The Supreme. Casper's Hybrid and Allswell's Supreme are comparable and most similar to each other, so we'll compare those two mattresses.

I had the chance to test both the Casper Hybrid and the Allswell Supreme firsthand. Both have advantages and weaknesses. In the following guide, we will see how the hybrid mattresses compare in several important categories: price, specs, return policy, warranty, set-up process, comfort, edge support, and motion transfer isolation. We will then make an overall recommendation.

Price and specs compared

Winner: Allswell. Though the Casper Hybrid is more affordable in Twin and Twin XL, Allswell has the edge in the more popular sizes. And when it comes to attractive design, Allswell also takes the cake.

When it comes to Twin and Twin XL mattresses, the Casper Hybrid is more affordable than the Allswell Supreme Hybrid. However, the Supreme has lower prices for the more popular sizes of Full, Queen, King, and California King. Casper regularly has discounts and promo codes so you might be able to find it cheaper in the size you want. Currently, the Allswell Supreme costs $99 more in Twin than the Casper Hybrid, $59 more in Twin XL, $191 less in Full, $181 less in Queen, and $101 less in King and California King.

Pricing for the Casper Hybrid Mattress:

Pricing for the Allswell Supreme Mattress:

When shopping for a bed, keep in mind, that you will likely have your mattress for at least 10 years. Any differences in prices end up working out to only a couple of cents per day over the lifetime of your bed. Plus, both companies offer 0% APR payment plans if you're unable to afford the full cost today.

The right size mattress for you will depend on two main factors: how big you are and if you're sharing a bed. A Full, Twin XL, or Twin mattress might be enough if you sleep alone. A Twin is sufficient for smaller individuals. However, if you're tall, you'll need at least a Twin XL. And, the Full is meant for people who are big and tall. Couples will want a Queen, King, or California King. The California King is designed for taller twosomes, while the King is for bigger couples.

My wife is tall, and I'm big, and we've found King beds serve us best. However, when testing beds, we sleep on a Queen since that is the most popular size. Both of the mattresses I tested in this comparison were Queen-sized.

There are design differences between the two hybrid mattresses. The Supreme Hybrid is two inches thicker than the Casper Hybrid (14 inches versus 12 inches). Both have four layers. The Supreme has a base support layer of individually wrapped coils, Energex foam for pressure relief, graphite and copper gel-infused memory foam for heat dissipation, and a euro top for a plush feel.

The durable base layer of the Casper Hybrid features individually-wrapped coils, then above it there's a foam zoned support layer for spine alignment, pressure-relieving memory foam, and a top layer of breathable comfort foam.

Both mattresses are made from foams with low VOC emissions, contain no ozone-depleting chemicals, and are CertiPUR-US certified.

Both beds have a white top and gray sides. I think the quilted top panel of the Supreme looks more luxurious. The Casper Hybrid is plain but clean looking. This is another factor I wouldn't put too much stock in since the mattress will be covered with a fitted sheet anyway. The covers on both beds are removable and washable, but we still recommend using a mattress protector.

Return policy and warranty compared

Winner: Casper. The two businesses have warranties and return policies that are almost exactly the same, but when you look at the fine print, Casper's warranty is a little better.

100-night risk-free trials are available from both Casper and Allswell. And, when you return your mattress, you get a full refund. Allswell will have one of their local haulers take the mattress away. Casper coordinates with a local charity or recycling center to dispose of your bed. We did not find any suspicious loopholes in the fine print of either company's return policy.

There is a slight difference between the 10-year warranties offered by the companies. Manufacturing defects, physical flaws, and significant indentation of an inch or more are covered by both warranties. But, you must use a supportive foundation, care for the mattress properly, and use it normally.

The difference between the two is Casper will either repair or replace your mattress, whereas Allswell will either replace it or give you a pro-rated refund, at their discretion. This could be a big deal if you face issues after having a mattress for nine years. One company will repair or replace it. The other might only give you a few bucks.

Set-up process compared

Winner: Allswell. Though it weighs significantly more, the Allswell Supreme was a bit easier to set up because it has handles and is firmer than the Casper Hybrid.

I don't have the precise weight of the Supreme mattress, but it's definitely heavier than the Casper Hybrid by at least 10 pounds. The Casper Hybrid in Queen weighs 85 pounds. Even just 10 pounds makes a big difference when trying to position a new mattress or when it's time to rotate it every 6 months.

However, there are two aspects of the Allswell Supreme that made it easier to move around. First, it comes with handles on each side. The Casper Hybrid does not. Also, the Supreme is firmer so it moves when you push it. The Casper Hybrid just bends and bunches up when you try to push it. It takes more effort to get it to move.

I've unboxed dozens of mattresses so I didn't run into any issues with these. The process was pretty standard. However, in the past, I've thrown out my back unboxing beds on my own so I suggest having someone assist you as you do it.

Once set up, both mattresses emitted an odor that is common of memory foam. Because of this, I recommend allowing each to air out (with the windows open, if possible) before sleeping on them. At the very least, unbox the mattress first thing in the morning so it has the whole day to air out. Don't put sheets on until right before bedtime.

Both companies offer a "white glove" delivery service if you'd prefer to skip the set-up process. The brands will send local delivery partners to your home to unbox your mattress, set it up where you want it, and remove the packaging.

There are small differences in the cost of this service depending on where you live. In Lansing, Michigan, where I live, Casper charges $149 for white glove delivery. This price includes the removal of your old mattress. With Allswell, the white glove treatment is $99. Or, you can pay an extra $50.99 to have your old mattress removed.

Note: As of March 18, 2020, the novel coronavirus hasn't affected either company's white glove delivery service, but we'll do out best to keep this post updated with accurate information.

Comfort compared

Winner: Allswell. The heat-dissipating properties of the Casper Hybrid give it the edge in comfort, though I found the average firmness of the Supreme was better suited to my body and sleeping style.

Comfort is an incredibly subjective mattress feature. Experts haven't even developed a standard way to objectively assess how firm a bed is. We do know that softer mattresses are generally better for petite individuals and side sleepers. Beds on the firm side tend to be ideal for heavy people, back pain sufferers, and back and stomach sleepers. I'm 6 feet tall, weigh 250 pounds, and I sleep on my side and stomach. I tend to prefer mattresses with an average firmness.

The Allswell Supreme and Casper Hybrid are pretty similar when it comes to firmness. Both are right around average, though I'd say the Casper is softer. Due to the softness and my hefty frame, the Casper Hybrid is a little too soft compared to the just-right feel of the Supreme, which gives me optimal comfort and support for my sleeping style and body. I still think the Casper Hybrid is great. The Allswell Supreme is just better for me.

When considering comfort, you also need to know if your mattress is going to trap heat. As a hot sleeper, I found the Casper Hybrid had a clear edge in this department. It has better breathability and heat dissipation. The Supreme remained hot throughout the night and didn't cool down when I left to use the bathroom.

Edge support compared

Winner: Allswell. The individually-wrapped coils and "reinforced quantum edge" of the Allswell Supreme give it superior edge support.

Edge support is important when choosing a bed. Good edge support will make it easier for you to sit on the side of your mattress and put on your socks. Plus, it will aid you in transitioning from sitting to standing. If the mattress sags on the edges, it's less comfortable to perform these activities. And, you may feel like you are falling off the side during the night.

Though both beds have decent edge support, the Allswell Supreme was clearly better. When I laid on the edge of the Supreme, I felt secure. I could also sit on the side to put on my socks and shoes. The give was much more pronounced with the Casper Hybrid. But, I never felt like I was going to fall off either mattress when my wife decided to annex my side of the bed and condemn me to teeter on the edge.

Motion transfer compared

Winner: Allswell. The Casper Hybrid failed our motion isolation test each time, while the Allswell Supreme performed a little bit better, though it still wasn't outstanding.

Without good motion transfer isolation, you'll constantly feel jostling as your partner gets up in the night or tosses and turns. If you want productive, uninterrupted sleep, a bed with outstanding motion dampening is a must.

I've created my own motion isolation test based on other industry tests using the materials I have available. First, I put a 12-ounce can of pop in the center of the mattress. Then, I drop a 20-pound weight from four feet above the bed so it lands 12 inches from the can. If the can remains upright after repeated tests, the mattress has great motion dampening. If it falls over consistently, it has bad motion isolation.

There was a pronounced difference in how well the two beds performed in my tests. The Casper Hybrid failed each time. It had poor motion isolation. The can would start to list on the Allswell Supreme after one drop and would fall over after the second. So, the motion dampening was okay but not outstanding.

In my experience, I tended to notice pets jumping on the bed and my wife's movements at night less often on the Allswell Supreme. The motion transfer isolation is just better.

The bottom line

Overall winner: If you share a bed with someone, go with the Allswell Supreme. Otherwise, you may prefer the Casper Hybrid. The better mattress for you comes down to your specific needs.

Unfortunately, I can't declare either mattress the clear winner. But I can give you a recommendation based on your situation. If you share a bed with someone, the Allswell Supreme is the better choice since it has superior edge support and motion transfer. It's also more affordable in the mattress sizes designed for couples.

However, if you sleep on your own, I think the Casper Hybrid is the better solution, especially if you are a hot side sleeper. Its softer support makes it easier to sleep on your side, but it may be a little too soft for back or stomach sleepers.

Of course, you could also take advantage of the brands' 100-night, risk-free trials and try out both options. Go with the bed that seems like a better fit. Then, return it and try the other if you are not satisfied within the 100-night window.

Or, you can go to any of Casper's locations across the country to test out the bed and enjoy a 30-minute nap session. All Target stores also offer Casper. On the other hand, Allswell is not currently available in brick-and-mortar stores.

When it comes to determining which bed is right for you, it's all a matter of personal preference. When picking a mattress, focus on the categories above that mean the most to you. And, remember you can always return your bed if you don't like it.
