Construction (Materials & Quality)

This pillow is covered in a high-end ultra cool knit polyethylene. This was designed to be both plush and cool, leaving sleepers comfortable and not too hot.

There is a layer surrounding the inside of the pillow that the brand calls a Comfort Shell. This is made with memory foam and a down alternative blend that was made to relieve pressure for the neck and head.

Inside the cover are two removable support inserts that are made from memory foam and a down alternative. These are the inserts that give sleepers the option of adjusting their pillow’s height and feel.

Firmness (Support & Feel)

With both inserts in, this pillow is about 6 to 7 inches tall. But when sleepers remove one insert, the pillow should measure between 4 to 5 inches tall. When sleepers remove all the inserts the height drops by another inch and a half or so.

After the sleeper’s head sinks down into the materials, researchers suggest that the height of the cushion should keep the sleeper’s head about 4 inches off the mattress. This loft is ideal for relieving pressure in both the neck and spine.

There isn’t a definitive approach to how you achieve that level, though, and a lot of a pillow’s success depends on the weight of your head, sleeping position, and the cushioning depth of your mattress.

As this is mostly made of memory materials, the foams should mold to the sleepers head and help to reduce pressure. The foam inserts benefit sleepers because they have the option to adjust the pillow in one of three ways. This makes this option versatile and allows it to work well for multiple sleeping positions and body types.

Back sleepers may find the highest loft, with both inserts, is too high for ideal comfort. By removing one or two inserts, back sleepers can optimize spinal alignment in their neck and sleep more comfortably.

Some Side sleepers may like the highest setting, though this will mostly be people with broader shoulders or bigger heads. The majority of people may prefer sleeping with one insert still in the pillow, as this could help keep their alignment in the most neutral position.

Stomach sleepers could do well with removing both inserts. This helps to keep their head properly elevated and should make it easier to breathe. One insert can also be a good choice for those that prefer a little more loft, though these folks might want to sleep with their head near the edge of the pillow so their mouth is not smothered by the cushioning of the product.

This pillow gives sleepers quite a few options, making it an overall good choice. Those looking for extra loft probably will get a lot of use out of this pillow.

Temperature Regulation

The cover uses a polyethylene knit fabric that was designed to stay cool to the touch. This should help hot sleepers rest cooler at night, allowing them to wake up without a sweaty bed head feel that can ruin the start of your day.

Noise & Smell

Some bedding products have an off-gassing smell when they come out of their packaging. This pillow may initially have this but it should disappear within a day or two.

Noise should hardly be an issue with this pillow as the foams and plush cover help to dampen any potential sounds that could be made.
