FAQs

Pick your firmness based on your typical sleeping position. The soft-medium pillow offers the perfect support for those that prefer to sleep on their stomach and back. The medium-firm pillow is recommended for those who regularly sleep on their side and back.

Yes, we want your bed to look nice and match the rest of your linens so we made sure the technology inside our pillows will still work even when used with a pillowcase.

Slumber Cloud products are designed to help manage heat and humidity build up. It is not an air conditioner with a set temperature degree, but it will react to your temperature all night long to reduce heat build up and manage temperature swings.

True to its name, the UltraCool Pillow is going to be the "cooler" of the two pillow options. Although you will still get great temperature control with the Core Pillow, this is designed more for sleepers who would prefer a traditional pillow with a modern temperature-regulation technology added in.

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

Reviews

Super comfy, pretty cool.

"I’m a stomach sleeper, and have been dealing with terrible hot flashes and insomnia. This pillow is squishy enough that I can sleep comfortably on my stomach. It does still get hot, to be honest, but nowhere near a hot as my regular pillow. And whenever I move it around, I can find another spot on it that’s truly cold. It’s been great."

— Amanda C. (1/5)

Not happy at all

"We received two of the ultra cool pillows several weeks ago and they both had a very distinctive odor. Two days ago we attempted to wash the pillows per the the instructions on the pillow. Unfortunately the pillow became severely waterlogged and weighs so much no the washer wont allow it to spin (a self balancing mode the washer has). This is awful!! Now all I have is two 60lb pillows that I cannot dry!!"

— Gary T. (1/5)

Rip off!!

"I've never been more dissapointed in a product. It absolutely does not feel any different than a regular pillow or pillow topper for your bed. A complete waste of money! You can get this a lot cheaper from other companies. I feel like your products actually make me hotter instead of cooler. I wouldn't recommend this company to anyone, unless you enjoy sweating in your sleep. I would ask for my money back except I've already tried there product. It's definitely nothing whaf they described on there website!!"

— Julie D. (1/5)

— WILLIAM H. (4/5)

"Not as described. Pillow has nothing cooling to it. Gets hot after a few minutes."

— Natacha (2/5)

"Had a bit of a smell at first, but very comfortable and just enough cooling for hot arizona days/nights"

— Dexter (5/5)

"After one months use, does NOT maintain shape. It will stay cool, but your constantly fighting a loaing battle withthe stuffing. Not worth $70"

— Laura (2/5)
