Yes, latex can feel hot, although it is less likely than memory foam to trap heat close to the body. Latex’s limited sinkage may help, but a thick comfort layer made of material that tends to trap warmth could make a bed sleep hotter. Mattress design and environmental factors matter, and the 3-hour-20-minute study did not establish how a bed would feel all night.
A latex mattress can still feel warm, but temperature performance varies by model design and materials. In a controlled test, microclimate temperatures were up to 3°C higher by the end across all bedding systems.
Latex tends to conform less closely than memory foam. Latex often has perforations for additional airflow, and its open-cell structure can promote heat dispersal; limited sinkage reduces the likelihood of trapping warmth. Memory foam’s closed-cell structure can trap heat.
For heat retention, latex is less likely than memory foam to trap heat close to the body, but either material can feel warm depending on the design.
Dunlop processing yields a denser material, but the available comparison does not establish that one type sleeps cooler. Vita Talalay describes applying air during production to create an open-cell structure.

Vita Talalay describes its production process as creating an open-cell structure.
Innerspring models usually excel at temperature regulation because air can circulate between the coils. Hybrids usually earn high marks for temperature control because of their breathable support cores, despite thicker comfort systems. In one controlled comparison, the latex ensemble’s back-zone humidity was double the innerspring ensemble’s and reached 50% RH.
Firmness and the comfort system can be important when assessing temperature control. Increased firmness may counteract heat-retention tendencies in some designs, and closer body contact leaves less surface area exposed to air for heat dispersal.
CDC/NIOSH recommends a sleep environment that is dark, quiet, cool, and comfortable. The study room was set at 17°C and 50% relative humidity.
Personal propensity together with environmental factors can have a greater overall impact on sleeping hot than the mattress itself, according to GoodBed. The study established a 3-hour-20-minute experimental protocol.
Limited sinkage reduces the likelihood that latex will trap warmth against the sleeper’s body. A thick comfort layer made of material that tends to trap warmth could make a bed sleep hotter, even with a breathable core.
The test found microclimate temperatures up to 3°C higher across all bedding systems by the end. The test lasted 3 hours and 20 minutes, not a full night. Individual heat sensitivity affects the likelihood of sleeping hot.
The experiment compared ensemble microclimate temperatures; it does not establish how every sleeper experiences latex.
Yes, newer memory-foam mattresses may have cooling gel layers and ventilation features that can reduce heat retention.
The test lasted only 3 hours and 20 minutes, not a full night. It does not establish whether latex feels cool at first contact or stays that way overnight. It found the latex ensemble’s microclimate temperature was up to 3°C higher by the end.
The latex ensemble had a higher measured microclimate temperature than the innerspring ensemble under controlled conditions. Across all bedding systems, temperatures were up to 3°C higher by the experiment’s end.
