Wright mattresses fight heat in layers. A 3Below gel-infused memory foam surface pulls warmth away from your skin, crosshatch-ventilated ZeroG foam layers move air through the core, and breathable mesh side panels let it escape. The W2.15 hybrid goes further with a copper-infused top, an active thermaphase cooling surface, and an 8-inch coil base that air flows straight through, which makes it our coolest mattress and the right pick for serious hot sleepers.
Why does temperature matter so much for sleep?
Because heat wrecks deep sleep. During our two-year tracked sleep study, breathability turned out to be one of the two factors that mattered most for how much deep sleep testers got, right alongside the balance of comfort and support. When testers slept hot, their deep sleep suffered, no matter how comfortable the mattress felt at bedtime. That finding shaped almost every material choice we've made since. The full story is in Inside Wright's R&D.
Traditional memory foam has a deserved reputation here. Dense foam that contours closely to your body also traps the heat your body gives off. We wanted memory foam's pressure relief without its furnace effect, so we engineered around it.
What is 3Below gel-infused memory foam?
3Below is the memory foam at the surface of both Wright mattresses. It's infused with gel that conducts heat away from your body instead of holding it against you, so the surface feels cool to the touch when you lie down and stays comfortable through the night. On the W1.27, it's a 1.5-inch layer of 4 lb foam. On the W2.15, it's a 1-inch layer that is also copper-infused and carries an active thermaphase cooling surface that works to regulate temperature at the exact spot where your body meets the bed.
How does air actually move through a Wright mattress?
Cool-touch surfaces only help if the heat has somewhere to go. Three design choices keep air moving:
- Crosshatch ventilation. The foam layers are cut with a crosshatch pattern that creates channels through the core of the mattress, so warm air isn't sealed inside solid foam.
- Breathable mesh side panels. The sides of the mattress are mesh, not solid fabric, giving the air in those channels an exit every time you move.
- A quilted top for airflow. The cover is quilted to promote airflow at the surface rather than pressing flat against the foam.
On the W2.15, there's a fourth path: the 8-inch pocket coil base is mostly open space, so the entire bottom two-thirds of the mattress breathes.
Which Wright mattress sleeps cooler?
| Cooling feature | W1.27 Memory Foam | W2.15 Hybrid |
|---|---|---|
| 3Below gel-infused memory foam surface | Yes (1.5") | Yes (1") |
| Gel-infused cool-touch top | Yes | Yes |
| Crosshatch-ventilated foam layers | Yes | Yes |
| Breathable mesh side panels | Yes | Yes |
| Quilted top for airflow | Yes | Yes |
| Copper-infused top layer | No | Yes |
| Active thermaphase cooling surface | No | Yes |
| Airflow through a coil base | No (foam base) | Yes (8" pocket coils) |
The W2.15 sleeps cooler than an all-foam mattress, full stop. That's the honest answer. The W1.27 is engineered for airflow well beyond typical memory foam, and most sleepers find it comfortable, but if overheating is the main reason you're replacing your current mattress, get the W2.15. Full spec comparisons are in W1.27 vs W2.15 and on the fact sheet.
What else can hot sleepers do?
Bedding matters almost as much as the mattress. Percale cotton is a hot sleeper's weave: crisp, light, and breathable. Our American Cotton sheets are Supima percale ($155-235 for a sheet set), and Stonewashed Linen ($220-260) breathes even in summer. And if you're worried a cooler mattress won't be enough, remember you don't have to guess: every Wright mattress comes with a 120-night trial that covers plenty of warm nights.

Frequently asked questions
Do Wright mattresses sleep hot?
No. Both use 3Below gel-infused memory foam, crosshatch-ventilated layers, breathable mesh side panels, and a quilted airflow top. The W2.15 hybrid adds a copper-infused thermaphase top and an open coil base, and it sleeps cooler than an all-foam mattress.
What is 3Below foam?
3Below is Wright's gel-infused memory foam. The gel conducts heat away from your body, so you get memory foam contouring with a cool-touch surface instead of trapped heat.
What is the thermaphase cooling surface on the W2.15?
It's an active cooling surface on the W2.15's copper-infused top layer that regulates temperature right where your body contacts the mattress.
Which Wright mattress is best for hot sleepers?
The W2.15 hybrid. It has every cooling feature the W1.27 has, plus a copper-infused thermaphase top and an 8-inch pocket coil base that lets air flow through the mattress.
Can I test the cooling before committing?
Yes. Every Wright mattress comes with a risk-free 120-night home trial. If it doesn't keep you cool, we pick it up free and refund you in full.
Sleep cooler starting this week. The W2.15 Hybrid and W1.27 Memory Foam both come with a 120-night risk-free trial, free shipping, and free in-home installation. More answers in the Wright Bedding FAQ.
