Consumer Reports recently answered a question that we’ve had for years – what’s the best mattress to sleep cool?
So far we’ve seen a lot of promises but not a lot of performance when it comes to cooling products. Except the Bed Jet which blows cooler air into your bed, we don’t find many cooling products that work.
Even special fabrics or cooling gels haven’t given us great results (but a higher price tag). That goes for pillows, sheets, mattress protectors and mattresses. So rather than a cooling mattress or cooling mattress cover you should focus on finding one that doesn’t sleep hot! In other words, on that’s temperature neutral.
Foam, especially memory foam, softens when it gets warm. Then you sink in, it traps your body heat and the temperature rises. Generally speaking, the softer or more plush or the more memory foam you have, the hotter you’ll sleep. Even people who normally sleep cold will find themselves getting sweaty.

Best Mattress to Sleep Cool?
We know this isn’t a comprehensive test but Consumer Reports came out with a list of the mattresses that trapped the least body heat. One of them is an Unbox Mattress top pick – Purple!
Sleep Number c2 Adjustable Air Mattress
Purple Mattress (the original was tested – the new Purple mattresses should be just as cool or more as they have springs and the breathable polymer layer – read our Purple bed review.) The fact that Purple isn’t a solid surface on top and that there’s no memory foam at all in it makes it sleep cooler than any mattress we’ve tested.
As Purple states on their website: Most mattresses don’t breathe. Memory foam, latex, even foam with “cooling” gel beads are hot because there is no place for air to flow.
Other materials are either completely solid or have very small airways that allow for little ventilation. Air doesn’t sleep hot (but may be uncomfortable in other ways).
How The Beds Were Tested
Consumer Reports put a copper plate on a mattress in a temperature-controlled room. “The plate is insulated on all sides except the one that comes in contact with the mattress. Then we run an electrical current through the plate”. Then they measured how much energy the copper plate uses to maintain a temperature of 98.6 degrees Fahrenheit (close to people’s average body temperature).
“If a mattress dissipates heat well, more energy is needed to maintain that temperature, but if the mattress retains heat, less energy is used,” – Consumer Reports
The 10 hour test looked at how much energy was used.
Beds that Sleep Warmest
Consumer Reports also looked at the worst performers – the mattresses that slept the warmest. Stay away from them if you want to sleep cool! It’s interesting that Sleep Number beds made both lists! That just goes to show that materials used makes a big difference! Also note that no boxed brands made the list (even though boxed brands are usually all foam).
Sleep Number 360 i8 Smart Bed Adjustable Air Mattress
Sleep on Latex Pure Green Firm Foam Mattress
Sleep Innovations’ Marley Foam Mattress
Charles P. Rogers St. Regis Pillowtop Innerspring Mattress
What materials should you avoid if you want to sleep cool? Soft memory foam. Gel helps cool it down at first, special fabrics can help. But over time your body heat will kick in and the mattress will sleep warm. Some mattresses are worse than others but overall, if you sink in, you create heat that has nowhere to go.
“You’re more likely to sleep warm on a foam mattress, compared with a hybrid innerspring, which we define as several inches of foam layers over metal springs. Despite having a layer of cooling gel foam, a larger percentage of foam models still retain warmth.”
Is your mattress too hot? It might be time to switch. Let us know if you’ve ever found a cooling mattress that works!
“The movie star mattress” with a lot of star power…Casper is also much loved and gets the top #1 rating by Consumer Reports for the best foam mattress.
You might think friendly ghost when you hear the unique name Casper, but I like to call Casper the movie star mattress because of the star power behind it. For example, Leonardo DiCaprio and Adam Levine are investors. You’ll also find celebrities and famous Instagrammers sleeping on a Casper.
Unbox Mattress requested and was given this queen size Casper Mattress by Casper for the purposes of this review. We weren’t paid to review Casper but we may earn a small commission should you buy one.
Promo codes change frequently so click the button to check for the latest Casper promo code.
Overall, we found the regular Casper mattress to be a decent bed but we’re more wowed by the marketing and their testing than the mattress itself. However, if you love memory foam beds and want a medium soft feel, Casper might be right for you. We’ve learned that each person is unique and after getting close to the firmness, features and price you want, the next best step is to do a sleep trial.
Here’s our Casper mattress review video (we hope to review one of their higher end mattresses too):
How Casper Mattress is Made
Take a look inside of a Casper mattress.
Let’s break down some facts about Casper…
Materials and Layers
Casper is made of all foam. There are no springs inside. There isn’t a lot of memory foam. Rather Casper beds consist of at least 79% regular / non-memory foam.
Casper has 4 layers of foam. All foam layers are Certi-Pur certified.
1.5” Open-Cell Foam
1.5” Responsive Memory Foam
1.5” Zoned Support™ layer provides optimal support for the shoulders and hips
5.0” Durable Support Foam
10” total height (foam and cover). We like the touches that distinguish this bed from other foam mattresses with the extra support where you need it. Casper calls it zoned support. They continue to test and make adjustments to their mattress based on customer feedback.
Firmness Casper is a medium firm mattress, right near the middle. It offers some sink but not a lot.
One purchaser will say Casper sleeps cool (and as I said I didn’t find complaints about the temperature) but others say it’s average temperature, neutral or even warm. Overheating didn’t seem to be a big issue, likely because there’s not very much memory foam in this bed.
Price of a Casper Mattress
You’re looking at under $1k for a queen and a king is $1195 but prices change so click below to find the current pricing.
Overall, Casper doesn’t sleep hot. The thing about foam, especially memory foam is that it warms up with body heat so even if you sleep cool, a mattress can make you sweat.
The cover is modern and clean but not fancy – we love that it zips off from the top instead of under the mattress, which makes for easier cleaning. The zipper is sturdy and it’s sort of fun to see inside.
Returns are easy and customer service is responsive.
Cons of Casper Mattress
Not as thick as some beds – although the extra material will usually add to the price.
It does have offgassing. Not the worst we’ve tested but not the best either.
Facebook Comments on What’s the Best Mattress?
We sort of hate when someone asks for friend’s recommendations for a mattress without giving any criteria. Everyone is different and it’s unlikely you’re going to have the same preferences or budget as your friends.
When we saw a thread about the best mattress, a friend raved about her Casper so we reached out to ask her what she thinks so far. She’s had hers a few years. Her response? She still loves it. Will you love it? There’s only one way to know. Try it out. And be sure to get one of the Casper mattress protectors to go with it. Nobody wants to think of what gets into your mattress without one!
Really though, that’s the beauty of a boxed mattress. You can sleep on it and that’s the best way to know once you’ve narrowed down your choices. Studies show that you’re just as likely to like a traditional mattress as a boxed one – it’s about 80% across the board.
Is Casper too Firm or Too Soft?
The biggest concerns people have with a mattress are usually the feel and the durability. The feel is subjective. The number one complaint we hear is it’s too hard or it’s too soft. As far as durability – Consumer Reports tests say they test a mattress to simulate 20 years of sleeping and Casper was at the top.
Overall Casper will be best for someone who likes medium firm memory foam mattresses without the heat. It’s probably not the ideal choice for heavier people who may want more than the 10 inches. Other than that you’ll need the 100 day trial to sleep on it to make up your mind.
You’ll like Casper if you already know you want some memory foam and softness but you like a medium firm feel. Love the sleep system – you save by buying sheets, pillows and mattress as a bundle.
We’re not hip enough to review this mattress.
Casper and the star power behind it is the biggest story because no one else in the boxed bed industry has done what they’ve done.
From nap pods in music stores to having Uber drivers deliver mattresses in New York City, they’re definitely chic. We’ve had a Google alert on their name to follow them for over a year and we’re just waiting for their nap pods to roll into our town so we can see them in person!
Casper officially launched on April 22, 2014, and they sold $1 million worth of product in the first 28 days. They’ve recently had product placed in some American Airline flights in first class. The big problem with that? People are stealing the bedding!
Casper is an award winning mattress
● Consumer Reports’ highest rated memory foam mattress under $1,000
● TIME ‘Invention of the Year’
● Fast Company’s ‘Innovation by Design’ winner
● Industrial Designers Society of America award winner
● Good Housekeeping 2018 Lab Pick
● #1 out of 27 top foam mattresses rated by Consumer Reports, beating out other brands such as Ghostbed, Lull, Tuft & Needle and more.
2017 Consumer Reports ranked Casper above Ghostbed and Purple but in a 2019 issue it rose to #1.
If we could pass out award for mattresses we review, we’d give Casper awards for…
The most personality packed in a mattress
Casper is one of the original bed in a box mattress companies that we credit with infusing fun into the otherwise snoozy mattress industry.
Casper is incredible at marketing and they have fun! During the eclipse of 2017 they took over part of Casper Wyoming (their namesake city). We think they should sponsor it like Half.com sponsored a city in Oregon for a year in 2000. They could give the city a bunch of beds in exchange!
Casper created a glamping moon gazing party that people could attend to watch the eclipse on a Casper, in Casper Wyoming! We don’t know if there were any celebrities in attendance or if they had a DJ but it looked like fun!
The stars really aligned for them too because Casper, Wyoming just happened to be one of the best places in the nation to view the eclipse. Casper Wyoming was in the Line of Totality. Talk about lucky!
If you call customer service you’ll want to be placed on hold so you can listen to the lullaby music play. We tested it out and it’s true. They supposedly also have bedtime stories if you press a certain number but we haven’t confirmed that. You can try it out by calling 1 888.498.0003.
When they launched, Casper packed actual books into the mattress box. You know how cereal boxes or cracker Jack have toys inside? Well Casper had books. Because people love to read before nodding off. Today the box comes with care interactions but we thought they should include a comic book or something.
The most engineers on staff
While they’re advertising is fun, Casper is serious about their mattress. They’ve got a testing lab where they monitor and test products, and have 30 engineers on staff. They even worked with a renowned polymer chemist to make our base foam more durable.
Today Casper has the Original Casper mattress which they continue to innovate on. It’s been re-engineered to add more support in places you need it like your hips and shoulders.
Don’t forget to always use a mattress protector with your mattress. Casper does carry a highly rated mattress protector to go with your bed. As we say never let your bed go naked. You don’t want moisture getting into the mattress and breaking it down. You want your mattress to last and be sanitary so be sure to protect it.
That wraps up our Casper mattress review. What do you think of this movie star mattress? Let me know in the comments and check the video description for a link to buy along with ourCasper promo code UNBOX to save $100 if you decide to try one out.
Finding the right boxed mattress for you is a bit like dating – you have to be willing to date different kinds until you find the right one. Except you get a full refund and the bed goes to charity after every breakup!
Casper Questions and Answers
Can I use a box spring with a Casper? When you order a Casper mattress you only get the top mattress. You’ll need a surface to put it on. You can use a box springs but there’s no need to but they’re outdated and were used when mattresses were thinner and weighed less. Today’s mattresses are heavier and are made mostly of foam. You need a surface to get your mattress off the ground and help distribute your weight evenly.
Instead of box springs, it’s preferable to use a platform, bed base, adjustable base, or even put your mattress on the floor.
How long are Casper mattresses expected to last?
In general a foam mattress like Casper is expected to last 5-7 years.
How thick is a Casper bed? The Casper mattress is 10 inches thick.
Hello Unboxers! Join us today for an honest DreamCloud mattress review. DreamCloud is a hybrid mattress which means it has memory foam and springs. Since writing this post, DreamCloud has changed some, read about DreamCloud changes here.
The main points you need to know about Dreamcloud are:
A full 15 inches in height
Hybrid luxury mattress that comes in a box (bag actually) and has springs
Memory foam with a firmer touch that won’t sink a lot or get too warm
Has side handles to help you move your mattress around on the bed easier
European style quilted top – each square is like a little cloud
Has an incredible 1 year trial period and lifetime warranty
Tufted European Style Hybrid Mattress in a Box
The top is a European pillow top style mattress with high end cashmere cover and tufting we don’t usually see in a boxed mattress. It really comes in a very large, durable bag. They offer a white glove service and will set up your mattress for you in your home.
To be honest, DreamCloud makes other mattresses in a box seem boring by comparison. There’s just a lot more going on with this mattress, so let’s get into the details.
We’re reviewing the queen size DreamCloud, which was given to us for the purpose of this review. We’re affiliates of DreamCloud.
This is the only mattress we’ve reviewed that has handles on the side!
We know how tough it can be to decide on an online mattress that you’ll love. This customer tried Purple mattress twice! But in the end she found and stuck with Dreamcloud.
Here’s what she said:
Got ours delivered and set up yesterday. So far it’s great! My hubby has back issues and we have gone through every mattress imaginable, from Tempurpedic to Purple. We had bought a Stearns Fosters and liked the firmness and the coils for support but not the huge price tag and the big buttons we could feel through several layers. This is our 11th mattress in the last 2 years….ELEVEN!! The last one we purchased was a Christelli mattress and it started having issues after 6mos but because they only have a 60 day trial period we are now out $2500. Looking forward to seeing how this mattress hold up over this next year.
Here are the mattress brands she tried, listed in order:
2. Linenspa (Amazon)
3. Tuft and needle
8. Stearns and Foster hybrid with cooling
9. Purple again
“So far it’s been great. My husband needs a firmer bed and this is firm enough for him but still soft enough for me.”
” My husband is a big guy and that’s the problem we had with all of the others. Some were just too thin of a mattress, 10” is not enough when it’s just foam.” Jennifer Smith Kiggans
When you hear the word cloud you think soft but the DreamCloud will only be your dream mattress if you like your bed on the firm end. In fact, it’s the most firm bed in a box mattress we’ve tested so far.
Honestly, we thought DreamCloud would be too soft. We usually steer away from a memory foam mattress for that reason. However, it’s actually more firm than expected. The mattress does warm up to your body, but not a lot. So if you sleep warm you can rest easy with this mattress.
The Dreamcloud mattress doesn’t actually come in a box, it comes in a double layer of bags. Yes, that’s right it’s boxless! It arrived in great condition and delivery was fast.
It weighs 94 lbs. The mattress was rolled up in layers of plastic and well protected. Everything about it spoke to its quality.
Dreamcloud offers a lease-to-own finance option if you are unable to pay in full which is helpful.
You can’t beat the sleep trial or warranty on this mattress! When you think of clouds, think eternity because it will be free from defects in workmanship and materials for as long as you own and use the mattress.
The lifetime warranty – or as long as you own it – works like this:
For the first 10 years of ownership, they will replace your mattress with a brand new DreamCloud at absolutely no charge to you if defective in workmanship and materials.
In years 10+ they will completely repair and re-cover your DreamCloud, or replace your DreamCloud and all transportation charges will be waived if a manufacturing defect(s) or a materials failure is confirmed to exist.
You get a full year sleep trial on this bed. That means you can get a full refund, no shipping or fees, if you change your mind in the first YEAR. Did you know Mattress Firm gives you 30 days trial on their mattresses and charges you almost $80 for a return? That’s why we love that you get plenty of time to decide what you think. Plus you’re not out anything if you don’t keep it.
Dreamcloud comes with a 20 year guarantee, which is also generous. While you may never need it, the warranty and sleep trial, helps give you peace of mind that you’ll be happy your purchase.
Some people mention a terrible smell and odor once it’s open, but it really wasn’t that terrible. There wasn’t a strong offgassing. Mattresses from the same brand may have more or less new bed smell to them depending on the manufacturing process and how long they aired out before being wrapped in plastic. So your bed may be different than someone else’s.
Dreamcloud is CertiPUR-US® approved. These foams are made without ozone depleters, PBDE flame retardants, mercury, lead and other heavy metals, formaldehyde, phthalates regulated by the Consumer Product Safety Commission. They are Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million).
Dreamcloud has 8 layers which isn’t as many as some other luxury brands but it has higher end detailing and a cashmere cover.

This is the dreamiest part of the mattress. Their Cashmere cover provides breathability, adds premium softness and is naturally resistant to bedbugs.
