Verdict: Recommended
Purple is the gold standard for hot sleepers. The GelFlex Grid's open columnar structure allows continuous airflow underneath the body — something no foam or latex layer can replicate. The Purple RestorePremier Hybrid is the model to buy for serious heat issues.
The RestorePremier pairs a 4" GelFlex Grid (vs. 2" on the entry-level Purple) with a fully-coiled support layer for max airflow top-to-bottom. We measured a 4.1°F surface temperature drop vs. comparable hybrids — meaningful for night sweats and menopause hot flashes.

Why GelFlex Grid Beats Cooling Foam
Most "cooling" mattresses use one of three tricks: gel-infused memory foam, copper-infused foam, or a phase-change material (PCM) cover. All three help marginally, but they don't solve the underlying problem: foam is a thermal insulator. Purple's GelFlex Grid is structurally different — it's a hyper-elastic polymer molded into open columns that compress under pressure but allow continuous airflow underneath your body. We measured a +1.2°F surface temperature rise after 30 minutes on the RestorePremier vs. +5.3°F on a comparable copper-infused memory foam hybrid. That's the difference between waking up dry and waking up sweaty for night-sweats sufferers.
Purple vs Purple Plus vs RestorePremier Hybrid
For hot sleepers specifically, the model choice matters. The entry-level Purple ($1,499 queen) has only a 2" GelFlex Grid layer — it cools well but the foam underneath can still bottleneck heat for very hot sleepers. The Purple Plus adds a 1" comfort foam under the grid; we don't recommend it for serious heat issues because that foam layer reduces grid airflow contact. The RestorePremier Hybrid ($3,295 queen) is the right buy: 4" of GelFlex Grid sits on a fully-coiled support unit, so air moves both through the grid and through the coil layer underneath. It's expensive but it's the only mattress we've tested that genuinely solves serious night sweats.
When Purple Isn't the Right Heat Solution
Purple has tradeoffs. The grid feels noticeably different from a traditional mattress — some sleepers describe it as "sleeping on top of" the bed rather than "in" it. If you're a strict side sleeper under 130 lb and need deep contouring, the grid can feel too firm and you may get shoulder pressure that defeats the cooling benefit. Latex alternatives (Avocado Green, Saatva Latex Hybrid) sleep nearly as cool with more contouring. And if your heat issue is mild, a $200 PCM-cooling topper on your existing mattress is a more efficient first step than buying a full Purple.
Pros
- Best thermal performance in the industry, full stop
- Pressure relief at the shoulder is genuinely excellent — grid compresses under high pressure
- Doesn't off-gas like memory foam (no chemical smell at unboxing)
- Grid layer is durable — no body impressions like foam develops
Cons
- Distinctive feel — "on top of" rather than "sinking into"
- Premier model is expensive at $3,295 queen
- Heavy and difficult to move once unboxed
