The Sleep Number True Temp Pillow comes in three shapes: Classic, Contour, and Ultimate. I tested the Classic, standard pillow, but for more room to roll around, Sleep Number also offers you a King size.
The cover to this pillow is super soft and cool to the touch. The sensation was so pleasant, I forewent a pillowcase a few times just to lie directly on it. The material is a mix of polyester and polyethylene, a fancy science term for a cooling material that helps draw heat from the body.
The outer fill of the pillow also uses fiberfill material to give it the same feel and softness of a down pillow, without the feathers. It is squishy and a little bouncy, so it’s easy to mold around your body shape.

Finally, the inner fill is a piece of breathable memory foam. The foam has perforations to keep your body heat from staying in the pillow and causing you to overheat. The brand also claims that the True Temp pillow is hypoallergenic.
In order to get a thorough look at how this pillow performed, we broke it down to numerical scores for cooling (how well the materials keep you from overheating), alignment (how well your neck is supported), adjustability (how moldable the pillow is), quality of materials, care (how easy it is to clean), and customer experience.
Out of all three sleep positions, I think the True Temp pillow is made for side sleepers, though the brand claims the product is best for back and stomach sleepers. The high loft and support level of this pillow allows the neck to stay in alignment with the spine.

I am not a back sleeper by nature, but this was the right pillow for keeping my neck in natural alignment as I attempted to sleep on my back with it. Because I have smaller frame, I felt that the loft was too high with the foam insert, so I removed it for a better night’s sleep on my back. Check out the best pillows for back sleepers for more information on what works.
I am primarily a stomach sleeper, so this is the most comfortable position for me. With the foam support center, this pillow just has too high of a loft to keep my neck in line with the rest of my spine. It did help when I unzipped the pillow and removed the foam, but it still wasn’t flat enough. I woke up with neck pain a few times.
Stomach sleepers should look for a firm pillow that is relatively flat. For options like this, check out our list of the best pillows for stomach sleepers.

This pillow ships free and comes with a 30-night sleep trial period. During this month, you can try out the True Temp pillow to see if it’s for you or if you want to exchange it for a new pillow that will better fit your needs.
The pillow also comes with a 1-year limited warranty. The warranty covers defects from workmanship but does not cover normal wear and tear a pillow gets over time such as discoloration, compression, and rips or tears.
Yes, especially if you sleep warm or need something customizable. Sleep Number offers an array of different pillows if the True Temp doesn’t suit you, including the PlushComfort pillow, for those who want a softer option and the Sleep Number ComfortFit pillow, which is a great pillow for combination sleepers.
Sleep Number pillows should last you about four to five years with proper care. This is because the materials are machine washable and the loft is pretty high. This is two to three years longer than most pillows, which means it is a good investment.
No. Pillows are made to support your head and keep your neck in alignment with the rest of your body. If you were to put your shoulders on the pillow, that could mess up both your neck and spinal alignment and give you neck or back pain in the morning.
Most of us know Sleep Number for offering some of the best mattresses for adjustability, but the True Temp pillow had the same quality I’d expect from a Sleep Number bed. It kept me cool, and had enough adjustable features so that I could sleep on my back or side. If you’re looking for your new favorite pillow, this is definitely a good luxury consideration.
The True Temp™ weighted blanket is Sleep Number’s take on a cooling blanket. It uses moisture-wicking technology and a cooling fabric blend to keep hot sleepers cool. It’s best for those who want to relax without overheating, but not ideal for those on a budget.
