Hot Sleeper Tips That Actually Work
Your mattress is the single biggest lever — but it doesn't work alone. These four changes will amplify your cooling mattress and help you stay comfortable all night.
Choose the Right Bedding
Best: 100% percale cotton, bamboo, or linen — breathable and moisture-wicking weaves. Avoid: sateen, polyester blends, and microfiber — they trap heat and feel clammy when damp. Thread count doesn't predict breathability; weave type does.
Set Your Room Temperature
The optimal bedroom temperature for sleep is 60–67°F. A ceiling fan running counterclockwise in summer creates a wind-chill effect that reduces perceived warmth by 4–6°F — no thermostat adjustment required.
Add a Breathable Mattress Protector
A breathable protector adds protection without heat — if you choose the right one. Look for: stretch-knit or Tencel surface with a TPU backing (waterproof but breathable). Avoid: vinyl or PVC backings, which trap heat at the surface.
Use a Cooling Pillow
Your head and neck generate significant heat during sleep. Dense foam pillows can be as problematic as a foam mattress. Look for: shredded latex or down-alternative fills with breathable cotton covers — or phase-change material pillow covers for severe hot sleepers.
Who Memory Foam Is Best For
Memory foam isn’t for everyone — but it’s the right fit for most sleepers. Here’s how to know.
Side Sleepers
The best choice. Side sleeping puts maximum pressure on hips and shoulders — memory foam fills the gap at the waist while cushioning contact points. Lull recommends the Original or Original Premium.
Back Sleepers
Excellent fit. Memory foam supports the natural lumbar curve without the hammock-sinking feeling. Medium-firm is ideal — the Lull Original hits this perfectly.
Couples
Best-in-class for motion isolation. If one partner moves, the other stays undisturbed. Also ideal when partners have different weights or sleep positions.
Hot Sleepers
Modern gel-infused memory foam runs significantly cooler than older foam. Open-cell construction with CertiPUR-US certified gel handles heat well. For extreme heat sleepers, consider the Luxe Hybrid.
*Not ideal for: stomach sleepers who need a very firm surface, or sleepers over 250 lbs who prefer hybrid bounce. Consider Lull’s Luxe Hybrid in those cases.

Which Lull Mattress Is Best for Hot Sleepers?
All four Lull mattresses are built with cooling in mind — gel-bead foam, open-cell construction, and breathable covers throughout. The hybrid models add coil airflow for maximum heat dissipation.
The Original Lull
5 layers · All-foam · Gel-bead cooling
Best for: Budget-conscious back & stomach sleepers, mild hot sleepers
Lull's core cooling technology at the most accessible price. A 1.5" gel-bead comfort layer plus open-cell HR foam keep airflow moving throughout the night. The best all-foam cooling option for budget-conscious hot sleepers.
- 1.5" gel-bead viscoelastic comfort layer (ILD 13)
- Open-cell foam construction throughout all 5 layers
- Hexagonal-tick quilted breathable cover
- CertiPUR-US® certified · 365-night trial · Lifetime warranty
Original Premium
5 layers · All-foam · Thicker gel-bead layer
Best for: Side sleepers, hip & shoulder pressure, moderate hot sleepers
A 2" gel-bead layer (vs. 1.5" in the Original) means more cooling surface area and more gel beads working throughout the night. The medium-firm feel reduces sinkage depth, limiting contact-surface heat buildup — same open-cell construction, more cooling capacity.
- 2" gel-bead comfort layer — 33% thicker than Original
- Medium-firm feel limits sinkage for better airflow
- Open-cell foam throughout all 5 layers
- 365-night trial · Lifetime warranty · Free shipping

Independently verified as the best-cooling mattress in the Lull lineup. The 8" pocket coil core (600+ coils, Queen) creates continuous airflow channels through the support layer. Gel foam captures surface heat.

Why Lull Wins for Side Sleepers

Lull vs the rest
Lull hasn’t cut corners on materials — ever. The difference is the business model: no showrooms, no sales staff, no retail markup. You get better foam for less.
| Lull | Casper / Purple | Store Mattress | |
|---|---|---|---|
| Price (Twin) | From $499 | $1,495 – $2,995 | $1,000 – $3,000+ |
| Trial Period | 365 nights | 100 nights | 30–90 days |

| Returns | Free pickup | Free pickup | Store drop-off |
| Foam Certified | CertiPUR-US® | CertiPUR-US® | Varies |
| Direct to Consumer | Yes — no markup | Yes | No — retail markup |
Same category. Better materials. Honest price. Lull hasn’t compromised its foam in a decade. The only thing we cut is the retail markup — which can be 50–70% of what you pay in a store.

A small sample from 50,000+ verified reviews.
“I’m a side sleeper and have always struggled with shoulder pain in the morning. After just a week on the Lull, that pain is completely gone. My shoulder sinks in just enough without bottoming out. Game changer.”
“Hip pain gone after the first night. I sleep on my side exclusively and this mattress cradles my hips perfectly while keeping my spine aligned. I wake up without stiffness for the first time in years.”
“My wife and I both sleep on our sides and we haven’t had a single morning where either of us complained about aching. The motion isolation is incredible too — I never feel her moving around.”
“Been a side sleeper my whole life and always dealt with numb arms in the morning. Two weeks on the Original Premium and the numbness is completely gone. The pressure relief at the shoulder is unlike anything I’ve tried — including memory foam mattresses from other brands at twice the price.”
“I sleep on my side with my knees pulled up (fetal position) and my hips were always killing me by morning. This mattress has a completely different feel — like it cradles the hip instead of pushing back against it. I’m genuinely shocked at how fast the difference was noticeable.”
“Both of us are side sleepers and we used to fight over which side of the bed was more comfortable. With the Lull we both sleep better. The motion isolation is incredible — I never feel Dana move at night. And no more hip pain for either of us in the morning.”
Hot Sleepers Who Found Their Answer
From night sweats to couples with different sleep temperatures — Lull customers who sleep hot share their experience.
I used to wake up drenched at 3am every single night. My partner kept our old mattress — I switched to the Lull Luxe Hybrid. First week: zero night sweats. I genuinely could not believe how much of a difference the mattress made.
My husband runs hot and I run cold — a nightmare combo for mattress shopping. We've had the Luxe Hybrid for 6 months. He sleeps cooler, I stay warm enough with the duvet. First mattress we've both been happy on in 10 years of marriage.
As someone going through perimenopause, night sweats were destroying my sleep. My doctor told me to try cooling bedding — I went further and got a new mattress. The Lull Original Premium made a real, measurable difference. I'm sleeping through the night again.
Was skeptical about the gel beads claim — I've tried gel-infused foam before and it didn't help. The Luxe Hybrid is genuinely different. I wake up at the same temperature I went to sleep at. That's never happened on any mattress I've owned.
Bought this after reading the Sleep Foundation review. I live in Phoenix — it gets to 115°F in summer and I sleep with my AC at 72 because I run so hot. The Luxe Hybrid is the first mattress that doesn't feel like a heat trap. Life-changing is not an overstatement.
My wife and I both sleep hot. We tried a Purple, a Casper, and a Nectar before landing on the Lull Luxe Hybrid. The combination of the gel layer and the coils is the real deal — no more 3am cover-throwing. This is the one.
