SweetNight CoolNest Review!
The SweetNight CoolNest Memory Foam Mattress is a budget-friendly cooling memory foam mattress designed for sleepers who want pressure relief without the premium price tag of luxury foam brands.
Unlike many traditional foam mattresses that trap heat, the CoolNest uses a phase-change cooling system, gel memory foam layers, and a ventilated cover to regulate temperature while maintaining body-contouring comfort.
Available in 12″, 14″, and 16″ heights, the mattress uses multiple foam layers and zoned support to help distribute body weight and maintain spinal alignment.

Gel-Infused Memory Foam

The support core stabilizes the mattress and helps maintain spinal alignment.
SweetNight CoolNest Review Performance
Pressure Relief – 4.3/5
Testing shows strong pressure relief due to the contouring memory foam layers.
Side sleepers especially benefit from the mattress’s ability to reduce pressure on the shoulders and hips.
Cooling – 4.5/5
Memory foam mattresses often retain heat, but the CoolNest performs better than most thanks to:
• PCM cooling foam
• gel-infused layers
• ventilated cover
These materials help regulate temperature and reduce overheating during sleep.
Motion Isolation – 5/5
Foam mattresses excel at motion isolation, and the CoolNest performs particularly well in this category.
Multiple foam layers absorb movement so couples are less likely to disturb each other during the night.
Edge Support – 3/5
Like most all-foam mattresses, edge support is average. Foam compresses more near the edges compared to hybrid or innerspring mattresses.

Pros
• strong cooling for a foam mattress
