Molecule at Mattress Overstock

Molecule mattresses, cut open to show where air moves.

Four foam beds. The Core has an open-cell comfort layer over a zoned support foam. The three Reflex beds put CoolVENT open-cell foam on top, and the two 12 in. ones add a layer of AirTEC foam under it.

Molecule’s photo of the bed

Molecule Core 10 in. Medium firm. Air moves through the open-cell comfort layer and the zoned foam under it, and slowly through the base. $599 QueenSee it in the lineup: Molecule Core 10 in.

Lie on it. Move across the cut. The air near you warms, and the layers that pass air carry it out through the sides while cool air comes in.

The drawing shows the idea. Air moves through the layers Molecule says pass air, and not through the others. It is not a measurement. Molecule publishes each bed’s height, not the depth of each layer, so the split between layers is illustrative.

Layer names, their order and what each layer does are Molecule’s own: the Core from its product page at moleculesleep.com, read on October 6, 2026; the Reflex 10 in., Reflex Boost 12 in. and Reflex Embrace 12 in. from Molecule’s product pages as archived on March 24, 2026, before Molecule replaced that Reflex line. Each bed’s height is to scale. Molecule does not publish the depth of each layer, so the split between layers is illustrative.

Molecule’s airflow figures, each compared with traditional memory foam, with no test named: CoolVENT foam, 4.5 times the airflow; AirTEC foam, 6 times; the Core’s zoned support foam, 2 times. The drawing at the top of the page shows the idea of air moving through those layers. It is not a measurement.
