Do Innerspring and Hybrid Mattresses Sleep Cooler Than Foam?

Generally, yes. A coil support core is mostly open space, so air moves freely around the springs instead of being trapped the way it is in solid foam. That airflow is the main reason innerspring and hybrid mattresses tend to sleep cooler than all-foam beds, which are known for retaining body heat.

Solid foam is dense and largely closed, so body heat builds up at the surface with little room to escape. A coil unit is the opposite: the space between and around each individually encased coil is open, so air circulates through the core as you move during the night, carrying heat away from the surface rather than holding it against you.

In a hybrid, the open-coil core sits beneath natural comfort layers that work the same way. Organic latex has an open-cell structure that breathes, and organic wool naturally wicks moisture. The result is a mattress that manages heat through the materials themselves rather than through added gels or chemical cooling treatments.

Some Avocado models add a second, shallower layer of individually wrapped micro-coils above the base unit, used in the Luxury Pillow-Top, Luxury Box-Top, and Wool mattresses. Because these coils are smaller and more numerous, they open thousands of additional air channels near the surface while contouring more closely to the body. See Coil Count and Innerspring Specifications.

No mattress controls temperature on its own. How warm or cool you sleep also depends on your bedding, your sleepwear, your bedroom, and your own body. What a coil core does is avoid the heat-trapping that solid foam is prone to, and let air move so heat is not held at the surface.

Generally, yes. A hybrid's coil core is mostly open space, so air moves around the coils and helps prevent the heat buildup that solid memory foam is known for. Avocado pairs that airflow with breathable organic latex and moisture-wicking organic wool.

Solid foam is dense and largely closed-cell, so it restricts airflow and tends to hold body heat at the surface. A coil core leaves open space for air to circulate instead.

No. Avocado manages heat through material design: an open coil core, breathable organic latex, and moisture-wicking organic wool, rather than gel layers or chemical cooling treatments.

Models with a micro-coil comfort layer (the Luxury Pillow-Top, Luxury Box-Top, and Wool mattresses) add extra air channels near the surface on top of the open base coil unit.
