At a Glance

Performance varies depending on your specific selection, but most CoolNest models stand out for deep cradling and pressure relief thanks to their memory foam and polyfoam comfort systems.

Testing Team Takeaways

To test the SweetNight CoolNest Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

“No matter the firmness or profile, both the all-foam and hybrid SweetNight CoolNest models delivered much-needed pressure relief when I was lying on my side. There was little to no pressure buildup around my hips and shoulders.”

“While some sleepers felt more comfortable on specific versions of the SweetNight CoolNest, all designs struck a solid balance between contouring and support without inhibiting position changes.”

“I appreciated the SweetNight CoolNest’s motion isolation. The hug of the bed was comfortable, but it also meant I could barely feel anything when my testing partner moved around on the mattress.”

Side Sleepers

The SweetNight CoolNest’s deep contouring is a good match for most side sleepers. By molding to the shape of the sleeper’s body, the memory foam effectively transfers pressure away from heavier areas like the hips and shoulders to reduce discomfort while promoting spinal alignment. Zoned support in the base layer enhances this effect.

Most versions of the SweetNight CoolNest are likely to be comfortable for side sleepers. However, as a general rule, the softer, higher profile models tend to let side sleepers under 130 pounds sink in at a more optimal level. In contrast, sleepers who weigh 130 pounds or more often favor the more balanced feel of the lower-profile, firmer options.

Back Sleepers

For back sleepers, the SweetNight CoolNest’s zoned support and close-conforming comfort layers can make it easier to maintain good posture throughout the night by cradling the lower back without letting the hips sag too much.

The thinner, firmer versions of the SweetNight CoolNest are particularly well suited to this sleep position due to their more supportive feel. That said, back sleepers under 130 pounds are likely to get the support they need from any profile of either the all-foam or the hybrid option.

Stomach Sleepers

Our testing team members under 130 pounds got sufficient support from most versions of the SweetNight CoolNest when lying on their stomachs, but the firmer, thinner options received the best ratings from testers who primarily use the stomach position. The zoned support around the midsection of the mattress helped testers under 130 pounds maintain good posture, while the conforming of the memory foam softened the surface. 

Stomach sleepers on our team weighing 130 pounds or more noticed that their midsections sunk in a bit too far, particularly on the plusher models, putting some stress on their lumbar regions.

SweetNight CoolNest Mattress Review Breakdown

The SweetNight CoolNest Mattress comes in all-foam and hybrid models. Both of these designs are available in profile of 12, 14, and 16 inches. These vary by firmness, equating to medium firm (6), medium (5), and medium soft (4), respectively. 

The all-foam and hybrid versions are both encased in a polyester cover. 

The SweetNight CoolNest Memory Foam begins with a layer of polyfoam infused with phase change material engineered to transfer heat away. A second comfort layer of gel-infused memory foam is intended to provide additional heat dissipation while molding to the body and easing pressure. 

Two more layers of polyfoam round out the comfort system for additional cushioning and support. A polyfoam support core reinforces the surface. Five firmness zones within the core target areas in need of extra support, such as the torso and hips, to promote good posture and enhance comfort.

SweetNight CoolNest (Foam)

The top layer of the SweetNight CoolNest Hybrid consists of gel-infused memory foam designed to contour closely and transfer away heat. A polyfoam comfort layer cushions the surface, while an additional layer of gel-infused memory foam deepens the contouring. 

An additional comfort layer contains polyfoam infused with phase change material, which is engineered to dissipate heat on contact, while two transitional polyfoam layers complete the comfort system. One of the transitional layers is zoned for targeted midsection support. A pocketed coil system makes up the support core, with dense polyfoam encasing perimeter for extra edge support.

SweetNight CoolNest Mattress Sizing

Size options for the SweetNight CoolNest depends on design and profile, as certain sizes are not currently available for some versions of the all-foam and hybrid models. We recommend checking size availability before committing to a specific design. Please note that none of the SweetNight CoolNest mattress models are sold in the twin XL size.
