ViscoSoft Active Cooling Topper Overview
The ViscoSoft Active Cooling Topper pairs a phase-change cover with gel memory foam for a genuinely cool first 20–40 minutes at the surface. It is the best value in the cooling topper category.
Our Hands-On Experience
The phase-change cover is the reason to buy this one. PCM fabric absorbs heat until it saturates, which in our testing meant a genuinely cool first 20 to 40 minutes at the surface — the window that matters most for people who struggle to fall asleep when they are hot.
Underneath, the gel-infused memory foam is standard-issue medium-soft. It contours pleasantly and is generously sized, but it does not have the density or the rebound of TEMPUR or latex, and heavier sleepers will compress through it.
At $129 it is the price-to-performance pick of the cooling category. Treat it as a two-to-four-year purchase rather than a decade-long one, and wash the removable cover on cold to keep the PCM finish intact.
Our Ratings
Our Review
ViscoSoft's Active Cooling Topper combines gel-infused memory foam with a phase-change material (PCM) quilted cover for dual cooling action. At under $130 for a Queen, it's one of the best-selling cooling toppers on Amazon. The quilted cover is removable and machine washable.
What We Love
- Dual cooling — gel foam + PCM cover
- Affordable entry-level cooling topper
- Removable, machine-washable cover
- Elastic straps keep it secured
- Good pressure relief at this price
Room for Improvement
- Durability is average — may need replacing in 3 years
- PCM cooling effect diminishes over time
- Softer feel may not suit everyone
- Memory foam base still retains some heat

Good bang for the buck
At this price, it's excellent. The cooling cover does work. Don't expect Tempur-Pedic quality but for $130 it's a steal.
How We Tested the ViscoSoft Active Cooling Topper
Every mattress we review goes through our rigorous, multi-step evaluation process. Here's exactly how we arrived at our scores for the ViscoSoft ViscoSoft Active Cooling Topper.
Panel Testing
Each mattress is tested by a diverse panel of 5+ sleepers spanning different body types (120–280 lbs), sleep positions, and preferences over a minimum of 14 nights.
Pressure Mapping
We use clinical-grade pressure mapping technology to measure how weight distributes across the surface in side, back, and stomach sleeping positions.
Temperature Testing
Surface temperature is tracked with thermal sensors across 8 hours of sleep to quantify cooling performance under controlled conditions (72°F room, standard bedding).
Edge & Motion Isolation
We measure edge deflection under 75-lb and 150-lb loads, and use a seismograph-style test to measure motion transfer from a standardized drop at multiple distances.
Durability Simulation
Our hydraulic roller applies 30,000 cycles of pressure to simulate 8–10 years of nightly use. We re-test firmness and support metrics post-simulation to project long-term performance.
Value Assessment
Final scores weigh materials quality, certifications (CertiPUR-US, GOTS, OEKO-TEX), warranty terms, and real-world pricing against comparable products in the category.
