14.11 g of moisture moved per m² per hour
It wicks moisture away
The tested Qube mattress moved 14.11 grams of moisture per square meter per hour in the lab—more than three times the tested conventional memory foam model.

Cooling Mattress for Hot Sleepers
Cooling comfort starts with managing heat and moisture. Element Materials Technology independently tested a Qube® mattress for moisture movement, heat flow and temperature response. Explore the measured results behind a mattress engineered for hot sleepers.

Cooling performance, measured.
Moisture movement. Heat release. Temperature response.

Measured temperature drop during the 45-second lift
It releases heat when pressure lifts
After three hours, the heated body-shaped fixture was briefly lifted. The average temperature reading fell from 36.2°C to 33.1°C during that lift.

Change from 60 to 180 minutes of the body-analog test
A small change over time
Qube’s average temperature reading was 36.0°C at 60 minutes and 36.2°C at 180 minutes—a change of just 0.2°C between those readings.
YES, and here's why...
Is Qube a good mattress for hot sleepers?
Qube is engineered for hot sleepers, with the patented Qube GelShell® Support System and 3-Dimensional Airflow. Independent mattress testing showed strong moisture movement and low water-vapor resistance compared with the conventional memory foam model tested in the same laboratory conditions.
Independent testing / Measured advantages
See the moisture-management difference.
Moisture movement
202%greater evaporative capacity
More moisture moved per hour in the sweating hot plate test.
g/m²/hr · Higher is better
Vapor breathability
67%lower water-vapor resistance
Less resistance to water vapor passing through the mattress.
m²·Pa/W · Lower is better
Heat flow with moisture
31%higher heat flow in the wet test
Greater measured heat flow while the test simulated perspiration.
W/m² · Higher is better

Measured evaporative capacity under the same controlled conditions.
Test 01 / Moisture movement
How did they test moisture wicking?
A sweating guarded hot plate simulated heat and moisture under controlled conditions. Qube measured 14.11 g/m²/hr of evaporative capacity; the tested conventional memory foam model measured 4.67 g/m²/hr. That is about 3.02 times as much, or 202% greater evaporative capacity. The same test also measured water-vapor resistance and heat flow under wet conditions.

Test 02 / Heat recovery
How did they test heat recovery?
A body-shaped fixture was heated to 37°C and supplied with moisture, then placed on the mattress for 180 minutes. The fixture was lifted for about 45 seconds before being replaced. Qube’s average reading fell from 36.2°C before the lift to 33.1°C at its end. The lab also recorded a heat-recovery area of 382.2°C·s over the lift-and-recovery period. This is a laboratory heat-release measurement.

Test 03 / Temperature over time
How did temperature change over time?
The heated body-analog test recorded temperature and relative humidity for 180 minutes before the lift. Qube’s average temperature readings were 36.0°C at 60 minutes, 36.2°C at 120 minutes and 36.2°C at 180 minutes. The change between the first and last of these readings was 0.2°C. These controlled laboratory measurements describe this test period, rather than a full night of sleep.
Moisture movement / Same lab conditions
More than 3× the moisture movement.
03 / Independent testing
Independent testing. Clear results.
Element Materials Technology in St. Paul, Minnesota tested a queen-size Qube mattress under controlled laboratory conditions. The tests used ANSI/RESNA SS-1:2019 parts 3 and 4 as procedural guides to measure heat and moisture performance.
