FAQs

Definitely! When you sleep hot but your partner sleeps cold we refer to this as being “thermally incompatible”. Our bedding is designed to automatically adjust to each sleeper’s ideal sleep temperature. With the unique ability to react to each sleeper's temperature independently, our bedding ensures that both you and your partner will sleep comfortably all night long.

Our comforters are designed to regulate your temperature even when placed inside a duvet cover. Feel free to use a duvet cover to get the finished look you are after as it will not have a drastic impact on the overall performance. However, we do recommend the Essential Duvet Cover for an added layer of Outlast® temperature-regulation and breathability.

Although all three comforter options are designed to help you sleep cooler and more comfortable, it's important to choose the version that best suits your sleeping needs. Below is a quick overview of each option to help you in this decision making:

UltraCool Comforter: A more traditional weight, the UltraCool Comforter pairs Outlast® temperature-regulation fiberfill with silky smooth outer fabric that is made of cooling nylon and spandex. The UltraCool Comforter is designed with 300 gsm fill weight – that of a traditional 3-season comforter but without the traditional heat build up. This comforter is the ideal choice for year-round use.

Lightweight Comforter: Our most popular comforter, the Lightweight Comforter uses Outlast® temperature-regulation fiberfill to regulate heat and humidity build up. Our thinnest option, this is best suited for "hot" sleepers who still want a little bit of weight on top of them.

Comforter: A twist on a classic comforter, this 3-season Comforter uses Outlast® temperature-regulation fiberfill to regulate heat and humidity build up. With a higher fillweight than the Lightweight Comforter the Comforter is ideal for those who need more of a 3-season weight or who prefer a bit more loft.

The difference between the two comforter weights is the amount of filling. The Lightweight option is significantly lighter & thinner at about 1/4th'' thick, and is the best option for hot sleepers.

The All Season Comforter is more of a three season weight, and for those who prefer a bit more loft & thickness at about 2''. Both of the comforters are filled with Outlast technology to assist with keeping you cool with proactive heat management.

These sheets and duvet cover are so comfy and cozy! They really do keep me cooler at nights too; which I've been fighting with my entire life - I'm an overheater! I already recommended them to my best friend.

Perfect for California Summer! I love the lightweight and how well it regulates heat, so that we are not hot nor cold. It is perfection. I was hesitant because of the cost but glad that I decided to purchase it

I have bought countless pillows, new bed, different positions, tried couch, bought new couch. Got this ultra cool pillow, so soft, literally feels like sleeping on a nice cool cloud. Slept the full night, first full night in over a year.

Reviews

Great for cool and hot sleepers!

"The quality is amazing and the fit is perfect for our King size duvet. The comforter works great for my husband who is a cool sleeper and I’m a very warm sleeper. It works well for us both so it’s a win win comforter! It’s easy to wash and we don’t have to take it a laundromat. We love this comforter and it’s worth the price."

— Renee F. (5/5)

NOT FINDING THIS TO BE COOLING

"The Performance Cotton Comforter from SlumberCloud is described as being a good warm weather blanket that is cooling for those who sleep hot. I am not finding this to be the case. I am sweaty and hot and have to remove the blanket during the night. Disappointed."

— Kayron S. (3/5)

Love my comforter.

"Love my performance comforter. It is light weight and I have no more night sweating. I would definitely recommend it."

— mary w. (5/5)

Great Comforter

"Love this comforter. It is light enough not to cause my joints to hurt from pressure and maintains a good neutral body temperature while sleeping. Got rid of a very heavy down comforter and replaced it with this Performance Cotton Comforter and have been sleeping great all night without getting hot or feeling joint pain from a comforter that is too heavy."

— Mike L. (5/5)

Perfect for summer

"I wanted a light weight covering that wouldn’t feel heavy on my feet or body, and that I could use in the summer months. This does both. It is noticeably cooler than a summer weight down one."

— Wilk (5/5)

— Anjoli A. (5/5)

— Jennifer A. (4/5)

Love the pillow

"Its been great, I love being able to remove stuffing and fluff it in the dryer on low if needed!"

— Cassandra C. (5/5)

Yes, it’s what you’ve been looking for

Best Comforter
