Independent Lab Results: SweetNight CoolNest in Sleep Foundation's 2026 Lists
Our own testing is one view. The most useful independent one this year comes from Sleep Foundation, whose Test Lab scored three CoolNest mattresses and put all of them on 2026 best-of lists next to Helix, Saatva, WinkBed, Nectar and Bear:
| Mattress | Sleep Foundation 2026 list | Award | Test Lab score |
|---|---|---|---|
| CoolNest® Memory Foam | Best Memory Foam Mattress | Best Cooling Memory Foam Mattress | 8.2/10 |
| CoolNest® Hybrid | Best Innerspring Mattress and Best Mattress for Sciatica | Best Cooling Mattress (both lists) | 7.9/10 |
| CoolNest® Ultra | Most Comfortable Mattresses | Best Mattress for Hot Sleepers | 8.5/10 |
| CoolNest® Ultra | Best Mattress for Back Pain Under $2,000 | Best for Couples | 8.5/10 |
How to use these results the way we suggest using any review: look past the award to the sub-scores that match your problem. The CoolNest Ultra's 10/10 for motion isolation matters most to couples. The Memory Foam's 9.5/10 for pressure relief matters to side sleepers with shoulder or hip pain. The Hybrid's 7.5/10 for back sleepers from 130 to 230 lb, the best of the three, matters if you sleep on your back. And read the caveats: Sleep Foundation found the all-foam models too soft for most heavier back and stomach sleepers.
