“I can cuddle without getting hot!.”

I’ve tried every ‘cooling’ comforter out there, and this is the first one that actually stays cool all night. It feels cold when you first get in bed — almost like hotel sheets — and somehow never gets stuffy or hot.

“No more waking up sweaty.”

“I used to wake up drenched in sweat, not anymore. This comforter is breathable, even during humid nights. It’s crazy how much cooler it stays compared to my old down comforter.”

“The dual sides make it perfect year round.”

“The dual-sided design is genius. One side feels silky and cool, the other is softer and cozier. I flip it depending on the weather, and it’s perfect either way.”

“The cooling tech actually works.”

“I was skeptical about the ‘phase-change’ thing but it’s real — I can feel it cool down as my body heats up. No more waking up at 3 a.m. sweating.”.

Frequently Asked Questions

Short answer: Unlike traditional comforters that trap heat, ThermaCool uses a 30% phase-change micro-gel fill that actively absorbs and stores excess body heat, keeping you cool throughout the entire night.

TENCEL™ Lyocell fibers are naturally breathable, silky-soft, and highly moisture-wicking — absorbing up to 68% more moisture than polyester. This helps you stay dry and comfortable even in humid environments.

We have a 60-day satisfaction guarantee. We pride ourselves in the quality of our pillow, so we want all our customers to be happy. If you have an issue, please contact our customer support team at support@dosaze.com.

Phase Change Material (PCM) is a temperature-regulating technology first developed by NASA to protect astronauts from extreme temperature swings in space. Our comforter uses the same science to keep you perfectly cool and balanced while you sleep.

A Total Game-Changer – Incredible Comfort and Support!

After my first Dosaze pillow purchase (the Standard Contoured Orthopedic Pillow), I was honestly disappointed — it felt too flat and didn’t provide the support I needed for back and side sleeping. I left an honest review reflecting that experience.

To Dosaze’s credit, their customer service reached out and offered to send me a replacement — the King size Contour Pillow — and wow, what a difference! This one is absolutely amazing. The design feels much more supportive and contoured in all the right ways. It gently cradles my neck and shoulders without feeling stiff, and I wake up with noticeably less tension.

I really appreciate that Dosaze stood behind their product and cared enough to make things right. The quality of the new pillow completely changed my perception of the brand. It’s supportive, comfortable, and worth the investment.

Highly recommend giving the Contour Pillow (King size) a try — it’s a big upgrade!

Great!

Alignment

This pillow supports my neck when side sleeping. I feel aligned properly with my neck and spine. Great pillow!

Amazing pillow!

My tension headaches from my old pillow disappeared!

Say so long to neck pain

I have had neck pain for ages, not until my daughter suggested buying your pillow has the pain gone away. It's a life changing pillow

Love this pillow

I deal with neck stiffness and this pillow has been terrific. I normally go for really firm pillows so I doubted this pillow at first because it felt thinner. I have been surprised at how great this pillow is. The design cradles my neck sleeping face up. It is also great for side sleeping.

Great pillows

I have had 3 cervical bone fusions and this is the only pillow that I will use.
