To begin let me just say that over the past 8-10 weeks, we’ve tested well over 20 of the most popular bed in a box mattresses out there. So with that said, we think we have a pretty good idea of which are the best at keeping you cool throughout the night. There’s a lot of people out there that are hot sleepers or maybe that live in hot climates so it’s important that your mattress is able to breathe well. Also, let me just add that none of the companies on this list paid us to make this video or write this post. We are 100% independent and not aligned with any one brand.
The Cocoon Chill is from Sealy, which is one of the biggest mattress companies in the world. However, the Cocoon series is actually their first bed in a box mattress. And what’s cool about Cocoon is that there are a few different options. They offer a Classic version and a Chill version, that’s the model we’ll be focusing on today. Then in addition to that, you can choose either a firm or soft option for each model.
In terms of construction, the Cocoon is comprised of several layers of foam. You’ve got a base layer of support foam. In the middle is another layer of foam designed for durability and then on top is what Sealy calls ‘Perfect Fit Memory Foam’. Now this is normally the part where I start talking about how memory foam mattresses tend to sleep hot. But that’s certainly not the case with the Cocoon Chill. The cover for the bed is infused with proprietary ‘Phase Change Material’ that’s supposed to absorb and dissipate heat. That’s a lot of fancy words – all I know is that this bed sleeps super cool. In fact, we almost thought something was wrong at first because the bed almost felt damp – it’s that cool.
In general though, it’s a very comfortable mattress. Sealy definitely knows what they are doing when it comes to mattresses. There’s a reason why Cocoon landed on our Top 5 Bed In A Box list. We tested out the firm option and it was still pretty soft and did a good job of cradling pressure points. We’d give the soft model a 5.5/10 on our firmness scale – so it’s on the firmer side of the spectrum. The bed supports you but it doesn’t feel too stiff, which is nice. It’s ideal for back and stomach sleepers but if you’re strictly a side sleeper, you may want to look at a mattress like Casper or GhostBed. However, if you’re a combo sleeper, you should be just fine.
Enjoying The Cool Cover Of The Cocoon Chill
In terms of pricing, the Cocoon Chill ranges from $549 for a twin to $1,149 for a king. So yes on the expensive side for a bed in a box mattress but we can help you out with a coupon code – use code RIZKNOWS for $100 Off any mattress.
Overall, in our opinion, the Cocoon Chill might just be the best option out there for hot sleepers. Big fan.
Next up is Purple, which has been on fire lately. I believe the company was actually just valued at over $1 billion, which is nuts.
Like most bed in a box mattresses, the bottom two layers are comprised of foam. But what makes Purple unique is their top layer. It’s comprised of hyper-elastic polymer, which is actually a material patented by the founders of the company, who by the way happen to be rocket scientists. This layer of hyper-elastic polymer material is 2″ thick and is laid out in a grid pattern. Here take a look:
Purple’s Hyper-Elastic Polymer Top Layer
It sort of feels like tiny gel squares but it’s not actually gel. It’s a pretty unique feeling. But in addition to the feeling, this top layer also has other benefits. Hyper-elastic polymer itself is naturally cooler than most memory foam and latex foam materials. In addition, as you can see above, Purple designed the top layer in a grid formation. This helps with airflow and prevents moisture from building up. The result is a tier 1 bed in terms of temperature regulation. It does a great job of keeping you cool as you sleep.
As far as the bed itself though, it’s also awesome. In fact, it took the number 1 spot on our Top 5 Best Bed In A Box list. We give it a 4.5 / 10 on our firmness scale so it’s on the softer side but it’s also quite supportive at the same time, which I know sounds kind of perplexing. But this is a very unique bed – Purple likes to say it’s “soft where you want it and firm where you need it”. It’s great for all kinds of sleepers. It provides plenty of support for back and stomach sleepers – you never feel as if you’re sinking into the mattress. Yet for side sleepers, the mattress cradles your pressure points very well. This mattress also performs quite well when it comes to limiting motion transfer – no worries if you or your partner happen to move around a lot in your sleep.
Payne Train Enjoying The Unique Feel Of The Purple Mattress
Now for pricing, Purple is positioned near the middle-to-higher end of the bed in a box industry. But honestly, considering the unique feel and quality of the materials in this mattress, I don’t think the price is that outrageous. It ranges from $699 for a twin XL to $1,299 for a king. And unfortunately, Purple doesn’t offer many coupon codes or sales but they sometimes offer a special where you can save $50-$100 or so on a mattress + platform base bundle.
Bottom line, yes, it’s an expensive mattress but we are huge fans of it. It took our number one spot for a reason. We really like the unique feel of that top layer.
Now we start moving into our tier 2 mattresses in terms of coolness. So what’s interesting about Bear is that they infuse their top layer with a graphite material that’s supposed to provide a cooling effect by dissipating heat and moisture. Then in addition to that, Bear uses a Celliant cover, which is supposed to help circulate blood flow and increase oxygen levels. And the FDA actually recognizes Celliant as a wellness product. Now I know that’s a lot of technical terms and in all honesty we don’t really understand it either. All we know is that the bed does a good job of keeping you cool. Jeff’s actually been sleeping on this mattress for over 15 months now so he has a pretty good idea. It can get quite hot here in Sacramento during the Summer and Jeff has never had an issue.
Jeff’s Been Sleeping On The Bear Mattress For Over 15 Months
Bear, like the others on this list so far, also made our overall top 5 list. It’s a solid bed. We give it a 6 out of 10 on our firmness scale so it’s slightly firmer than the Cocoon Chill. Still, it’s very comfortable and has a slight memory foam feel to it, which is nice. It’s best for back and stomach sleepers but side sleepers should be just fine as well since the bed does soften up a little over time. Pricing is very affordable with all mattresses coming in below the $1,000 mark. Plus, you can use code RIZ125 for $125 off any mattress.
Overall, we like Bear Mattress a lot. Jeff loves his. It’s great for back and stomach sleepers and it sleeps pretty cool as well. You can learn more in our full Bear Mattress Review.
Next up is Layla, which is quite unique as well. Their mattress is actually flippable. But before we tackle that, let’s talk about coolness. Layla actually infuses their foam with copper, which has very high thermal conductivity. Then for the cover, Layla infused thermo-gel. The theory here is that when the bed compresses, the copper and gel particles come in contact with each other and help transfer heat away from your body. Again this is some nerd talk here that we really don’t understand but the bottom line is that it seems to work. The bed sleeps cool and we really like the cover.
Getting back to what makes this bed really unique though is how it’s constructed. The think support layer rather than being on the bottom is actually in the middle. Then on top of that is another 2″ layer of support foam. Then on one side is a 3″ layer of that copper infused memory foam that I touched on above – that’s the soft side. On the opposite side is a 1″ layer of copper infused memory foam – that’s the firm side. We give the soft side a 5/10 on our firmness scale. So just a really nice balance overall between being soft and supportive. For the firm side, we give it a 6.5 out of 10 so definitely on the firm side of the spectrum. This side is best for 100% back and stomach sleepers as well as people over 250 pounds.
Love The Versatility Of The Layla Mattress
Pricing for Layla is also very affordable. All of their mattresses are priced below $1,000. And we can make it even cheaper for you – right now, you can get $100 off the Layla mattress. Overall, we love the versatility of this mattress. Plus, it’s just a solid bed all the way around.
Last up in the tier 2 category is YogaBed. This is a bed we like a lot. It made the honorable mention section for our Top 5 Best Bed In A Box list. Like the other brands on this list, YogaBed has a bunch of fancy, technical terms for why their cover and top layer helps keep you cool. And as much as I generally dislike that kind of marketing rhetoric, I do kind of have to agree. This bed sleeps pretty darn cool. Both Jeff and I tested this mattress in the hot August summer nights of Northern California and we both agreed the mattress performed quite well.
In addition to being quite cool, this is also a very comfortable mattress. It’s one of those mattresses that you don’t want to get up from when your alarm goes off in the morning. It has a very nice memory foam feel to it. Still, you never get that stuck-in-the-mud feeling. Overall, we give it a 5.25/10 on our firmness scale. It’s great for back, stomach and side sleepers as well as combo sleepers. It also performs quite well when it comes to limiting motion transfer – no issues there.
Very Nice Memory Foam Feel With YogaBed
As far as pricing, YogaBed is kind of middle of the road for the bed in a box industry. Prices range from $449 for a twin to $1,049 for a king. But the good news is that they do regularly run coupon codes and sales [check current promotions on Marpac.com].
Bottom line, if you love the traditional memory foam feel and you’re a hot sleeper, YogaBed is a great option.
