A modest, real improvement over the Green Tea for around fifty dollars more — but it is a cooler all-foam mattress, not a cool one. If heat is a mild annoyance, this solves it. If heat is the reason you are replacing your current mattress, buy a hybrid instead.
What the cooling actually is
The Cooling Essential swaps the Green Tea's plain memory foam comfort layer for a gel-infused version and pairs it with a more breathable knit cover. Gel infusion works by giving heat somewhere to go on first contact — it raises the foam's thermal mass, so the surface feels cooler when you lie down. What it does not do is move heat away over the course of a night. Once the gel reaches your body temperature, which typically takes an hour or two, the mattress behaves like any other all-foam bed. That is the honest ceiling on this technology at this price.
How it compares to the Green Tea
Side by side, the Cooling Essential feels slightly more responsive and slightly less dense than the Green Tea, in addition to running a bit cooler at first contact. The comfort layer is a touch thinner, so pressure relief for side sleepers is marginally shallower. Support, edge behavior, and expected lifespan are essentially the same — these are siblings, not different tiers. If temperature is not on your list of complaints, the Green Tea at a lower price is the better value.
Who this suits
The right buyer here is specific: someone shopping under $350 who has noticed they get warm on foam but would not describe themselves as a hot sleeper. For that person, the gel layer and better cover are enough to remove the annoyance. Anyone whose primary complaint is overheating should skip the entire budget foam category. A pocketed-coil hybrid at the same price — the Allswell is the obvious example — moves air through the mattress structurally rather than relying on a surface effect, and the difference is not subtle.
Support and longevity
Support comes from a high-density base foam with no zoning or reinforcement, which is standard for the price. Expect the same three-to-six-year window of nightly adult use as the Green Tea, with the same caveat that heavier sleepers will compress the comfort layer faster. Edge support is soft; if you sit on the side of the bed to put on shoes, you will feel it give.
What it does well
- +Genuinely cooler to the touch than the standard Green Tea
- +More breathable cover fabric
- +Still comfortably under $350 for a queen
- +CertiPUR-US certified
- +Slightly more responsive feel than plain memory foam
Where it falls short
- −Cooling is a first-contact effect, not sustained overnight temperature control
- −Thinner comfort layer than the Green Tea reduces pressure relief slightly
- −No coil layer, so no structural airflow
- −Same soft edges and same lifespan limits as the cheaper sibling
Buy it if
- ✓Budget shoppers who sleep slightly warm
- ✓Side and back sleepers under 200 pounds
- ✓Anyone who liked the Green Tea but wants a bit more temperature help
Skip it if
- ✗You wake up sweating regularly
- ✗You need coil support or strong edges
- ✗You are over 230 pounds
