We have a 10" split king organic latex bed with three 3" layers: firm Dunlop/medium Dunlop/soft Talalay. We have found this bed to be much warmer than a previous coil mattress, causing us to progressively remove first the coverlet and then the blanket from the bed, leaving us with only a top sheet covering us. Even in the current cool weather that allows our room temp to drop to ~56-57 degrees F, we end up too hot on the parts of us touching the mattress and cool/cold on the remainder.
The mattress is currently on top of the mattress foundation that SleepEZ sells, which have slats ~2.5-3" apart. There is nothing blocking airflow below the slats (which may not impact anything as the holes in the Dunlop layers don’t seem to go all the way through the layer and the holes in each layer don’t line up anyway). Our sheets are 300 thread count, so shouldn’t be especially hot. The cotton coverlet used to be our summer bedding, but given how hot the mattress runs, we are using it in winter. I’m 5’9" 140# and my wife is 5’4" 130#.
We tried removing the included mattress protector which helped a little. We also tried removing the top layer of the included cotton/wool mattress cover which helped more (and made the mattress feel softer/more comfortable). However, the bed still gets warm enough that it makes us have to try to move to different parts of the mattress during the night to find cooler spots.
Does anyone have any suggestions to help this bed sleep cooler?
John - Thank you for the BedJet suggestion. It looks interesting but my wife doesn’t want a gizmo running while we are asleep in the room. We might try switching to linen bedding which is supposed to run a little cooler. Still, I wonder if there is a latex mattress that has more holes or airflow channels.
Thank you for choosing SleepEZ for your mattress needs! Latex mattresses, especially with a Talalay comfort layer, are among the cooler options available. Talalay latex features an open-cell structure that enhances breathability, making it softer and allowing for better airflow. This design prevents heat from being trapped, resulting in a cooler sleep surface.
However, sometimes new bedding or sheets can inadvertently trap body heat, even with a latex mattress. While your lower thread-count (300) sheets are a good start, the fabric type plays a significant role in breathability.
For optimal cooling, I recommend:
Lightweight, breathable fabrics: Look for sheets made of linen, bamboo, or percale-weave cotton to improve airflow.
Moisture-wicking options: Materials like Tencel or eucalyptus fibers are designed to keep you cool and dry throughout the night.
Bamboo fiber toppers: These can enhance breathability while adding a touch of plushness to your mattress surface.
Additionally, heavy mattress pads or waterproof protectors can trap heat, though it sounds like removing your mattress protector already made a difference.
I hope this information helps! If you’d like to discuss further or need assistance, please don’t hesitate to reach out by phone anytime.
