Casper encourages our team to experiment and try new things. We added corner loops to work with the existing Casper Duvet Cover snaps, which hold your cover on nice and tight. When we sleep-tested and ranked the various competitive duvets, the sewn-through construction also rated as our top pick.

Waking up first thing in the morning and grabbing my infrared thermometer, I registered 91 degrees. More than 25% off planned retail price. Turning it on full blast in a room will have you running after stray papers and shuddering at the number of dust bunnies uncovered.

"At least this summer I can roast in bed" said no one, ever.

The Aurora is an extremely comfortable mattress.

Duvet shells need to be woven tightly so that the fluffy down can’t escape.

We wanted to launch this controversial design to a community that would appreciate the design work and provide us with the kind of feedback that would help us bring a new product to market.

Finding the right proportion of fill power and fill weight is key to creating a duvet that is warm yet lightweight. We already knew about Merino wool’s incredible properties from the performance apparel industry and so it was natural to explore whether we could improve its properties with other materials. Though the development process can vary for each project, these are the stages we typically see: Explorations that test ideas and functionality. Most people say they sleep too hot — or so we thought.

More than 15% off planned retail price.

The wool duvet started as a spin-off exploration from our more traditional. In the end, we engineered a unique 85% merino, 15% low-melt synthetic fiber textile that holds the wool fibers evenly and securely together. New comments cannot be posted and votes cannot be cast, Press J to jump to the feed. Video analysis showed that this drop was almost always caused when overheated testers tossed off the covers.

Especially if you're the kind of sleeper that absolutely has to have a heavier duvet or comforter over your sheets, no matter what the weather, this is the one to choose.

They're made with the company's proprietary TitanCool technology. They know that getting humidity out is a BIG way to add loads of comfort for all of the hot sleepers out there. A down only construction had the opposite effect: While wool clearly helped with moisture regulation, too much wool would make the duvet too heavy. The sheets are powered by the infrared heat of your body and also absorb and trap odors. The composition of the mattress is fairly standard, with layers of foam of various densities surrounding individually encased springs.

I've been using their mattress for 3 years now and have been satisfied.

Appearance and function match the final product, but is made with different manufacturing methods.

These internal walls have flaps through which the down is filled into the boxes. Our in-house testing confirmed that the temperature variance between the complex baffle box and simpler sewn-through constructions was negligible for an indoor environment like the bedroom. Casper Humidity Fighting Duvet. If you thought down comforters are too hot for summer, think again.

It's a stunning amount of material science packed into a very nice set of sheets. Once we stabilized temperatures, we discovered that humidity was the real culprit. Plus, as time goes on and the duvet goes through wash/dry cycles, down will migrate between boxes (via the flaps on the internal walls) and likely get overly full at the base of duvet—there is no way to fix this. To avoid trapping our precious down clusters, the majority of our sewing happens before the down is added.

The cluster has no hard quills (like feathers) and has many fluffy filaments growing in all directions. The below illustrates our consistent findings across even some of our earliest prototypes.

Thanks to an innovative layer of merino wool, it helps fight the sweat-inducing, suffocating effects of humidity by wicking away moisture. Which duvet?

Seriously, every move we made it crackled and woke us up. My wife sleeps considerably hotter than I do and said she noticed a drastic difference in how hot she got overnight.

You can find me on Twitter (@sunstreaker84), Facebook, and Google . First thing my husband said after waking up was "I feel like I slept on an empty bad of potato chips all night." Sewn-through duvets are much simpler, with two layers of fabric stitched together to create pockets (usually square) for fill. By pledging you agree to Kickstarter's Terms of Use, Privacy Policy, and Cookie Policy. A "breezy" 89 degrees.

Merino fibers are finer than normal wool and they are also more flexible.

It's summer and, now more than ever, you need your sleep.

(Same results!). Our plan is to have supporter's duvets shipping by mid-November but we've put December to be on the safe side. What I thought was a duvet was a duvet cover. We wanted to dive deeper into the microclimate of sleep, exploring heat indexes, dew points, and variances. Their stretchiness means they'll accommodate even the tallest of mattresses. As your body warms up, you release humidity in sweat which makes it feel even hotter under your blanket and it becomes a big sweaty mess.

Opinions expressed by Forbes Contributors are their own.

Finally, we decided to make one side of the outer shell gray to differentiate between our down-only duvet. If you're looking to truly hack your sleep, and won't rest, literally, until you're as cold as you can possibly be all night long, then you need to check out EightSleep.

Narrow channels also drape nicely from head to toe and side to side. In addition to, I am a contributor at
