Sleeping hot turns restful nights into hours of tossing, turning, and adjusting the thermostat. The Leesa Chill Collection is built to solve that problem with four cooling mattresses engineered for hot sleepers: Legend Chill Hybrid, Sapira Chill Hybrid, Oasis Chill Hybrid, and Studio Chill Hybrid. Each combines cooling technology with hybrid construction to deliver a measurably cooler sleep surface. 

The flagship Sapira Chill Hybrid holds twelve separate recognitions - including Best Overall Hybrid Mattress 2026 from Wired, Best Hybrid Mattress 2026 from Forbes, and Best Overall Cooling Mattress from AARP - making it the most-decorated mattress in Leesa's catalog. The Legend Chill Hybrid adds three more, including a Wirecutter Top Pick and Forbes' Best Cooling Mattress for Back Pain. Fifteen awards across two models is award-backed recognition of Leesa's reputation for hot-sleeper comfort.

Introduction to the Leesa Chill Collection 

The Chill Collection is Leesa's dedicated line for temperature-regulated sleep, with an option for every hot sleeper and budget. It targets several overlapping groups: people who run hot year-round, couples with mismatched temperature preferences, side sleepers who need cooling plus pressure relief, and shoppers who want premium cooling without giving up comfort or support. 

Cooling Technology Behind the Chill Collection 

A cooling mattress works by combining cooling fibers, phase-change materials, and airflow-friendly construction to pull heat away from the body and keep the surface temperature stable. The Chill Collection layers several of these mechanisms rather than relying on one. 

  • Ultra Cool Cover: A quilted top layer with cooling fibers that wicks moisture and actively moves heat away from the body, rather than just feeling cool to the touch.
  • Phase-change materials: Absorb excess heat when you're warm and release it as your body temperature drops, buffering temperature swings through the night.
  • Gel-infused foams: Conduct heat away from pressure points, where heat tends to build up most.
  • GreenFlex® BioFoam: Leesa's in-house plant-based foam, built with an open-cell structure that lets heat escape rather than trapping it, a meaningful difference from conventional closed-cell memory foam, which is the single most heat-retentive material in most mattresses. More on this below.
  • Hybrid coil layers: Individually wrapped coils create airflow channels through the mattress core — unlike solid foam, which traps heat.

Independent Testing Backs This Up 

AARP's cooling gun test found the Sapira Chill Hybrid dissipated all but about 8 degrees of added heat, and a separate AARP cooling-mattress evaluation measured 7.9 degrees of retained heat — both placing it among the stronger performers AARP has tested.

Leesa Sapira Chill Hybrid — Most Popular Cooling 

The Sapira Chill Hybrid is Leesa's most-awarded mattress, with twelve separate recognitions spanning overall performance, cooling, side-sleeper comfort, and pain relief. Two publications named it their best hybrid outright and independently of each other: Wired's Best Overall Hybrid Mattress 2026 and Forbes' Best Hybrid Mattress 2026. Sleep Foundation called it the Most Comfortable Hybrid Mattress, and NCOA named it Most Comfortable Mattress across all categories. Its cooling record is the deepest in the collection. AARP recognized it three separate times — Best Overall Cooling Mattress, Best Hybrid Mattress for Cooling, and Best Cooling Mattress for Side Sleepers — and Sleepopolis independently named it Best Cooling Mattress for Side Sleepers as well. 

It comes in three firmness options — plush, medium-firm, and firm — so sleepers can match comfort level to body type and position. As a general guide: plush suits lighter and strict side sleepers, medium firm works for combination sleepers and couples with mismatched preferences, and firm suits back/stomach sleepers or those on the heavier side. (These are general firmness-matching guidelines, not model-specific test results.) 

Its seven-layer construction stacks every cooling mechanism the collection uses: an Ultra Cool phase-change cover, gel-infused quilt foam, open-cell GreenFlex® BioFoam, responsive memory foam, a high-density transition layer, an 8-inch zoned pocketed coil system, and a support core. That combination produced AARP's measured 8-degree heat dissipation in cooling gun testing. 

Best for: hot sleepers across the board, people dealing with night sweats or hot flashes, side sleepers who need cooling plus pressure relief, and couples who want one mattress that works for both partners' temperature and comfort needs.  

Leesa Legend Chill Hybrid — Best Luxury Cooling 

The Legend Chill Hybrid is Leesa's luxury cooling model, combining the Ultra Cool Cover and gel-infused comfort foams with a zoned dual-hybrid coil system. The zoning offers softer support at the shoulders for side sleepers, firmer support through the lumbar region, and reinforced support at the hips. 

Wirecutter named it a Top Pick 2026 for hybrid mattresses and Forbes named the Legend Chill Hybrid Best Cooling Mattress for Back Pain, noting its dual-coil construction and firmness that sits between medium and firm — a combination that gives it more targeted support than a typical medium mattress. Reinforced perimeter coils add stable edge support, which matters for couples and anyone who sits on the mattress edge to get dressed. 

Best for: hot sleepers who want a long-term luxury investment, couples who want strong motion isolation plus cooling, and back-pain sufferers who need firmer, zoned support. 

Leesa Oasis Chill Hybrid — Contoured Cooling 

The Oasis Chill Hybrid sits in the middle of the lineup, built for combination sleepers who shift between side, back, and stomach positions and want adaptive support along with cooling. Its foam comfort layers, including a cutting-edge copper-infused memory foam, contour to the body while the hybrid coil base keeps airflow moving. It's the one Chill model built without GreenFlex® BioFoam, using copper-infused and gel-infused foams in its comfort layers instead. It remains GREENGUARD Gold certified, CertiPUR-US® certified, and fiberglass-free. 

Best for: combination sleepers, people who want noticeable contouring without excessive sinkage, and shoppers positioned between the luxury Legend Chill Hybrid and value-focused Studio Chill Hybrid. 

Leesa Studio Chill Hybrid — Best Value Cooling 

The Studio Chill Hybrid is the collection's most affordable model, aimed at budget-conscious shoppers who still want temperature regulation. Its construction uses an Ultra Cool Cover that dissipates heat while the copper-infused memory foam, open-cell GreenFlex Foam, and individually wrapped steel spring system keep the interior cool as well. 

Best for: guest rooms, first apartments, solo sleepers in smaller spaces, and anyone prioritizing cooling on a tighter budget. 

Why the Chill Collection Stands Out for Hot Sleepers 

A "hot sleeper" is someone who frequently wakes up warm, sweats overnight, or finds that standard mattresses trap body heat. Contributing factors include individual metabolism, hormonal changes (including menopause), certain medications, sharing a bed with a partner who runs warm, and mattresses that trap rather than release heat. 

Traditional memory foam is especially prone to heat retention because of its dense, conforming structure — heat has nowhere to go. Even some hybrids fall short if their comfort layers use heat-trapping materials or their spring systems don't allow enough airflow. 

The Chill Collection's case rests on three things: 

  1. Layered cooling materials — the Ultra Cool Cover, phase-change materials, and gel infusions working together rather than a single cooling gimmick.
  2. Breathable foam at the core of the comfort layers — open-cell GreenFlex® BioFoam, which lets heat escape rather than sealing it in. Most cooling technology is added on top of a mattress; this addresses heat retention at the material level, in the layer that sits closest to your body.
  3. Hybrid airflow architecture — individually wrapped coils that let air circulate through the mattress core.
  4. Independently measured performance — AARP's testing of the Sapira Chill Hybrid found roughly 8 degrees of heat retention after heat exposure, a strong result relative to the mattresses AARP has tested overall.

 
Who Benefits From the Chill Collection 

Side sleepers: Side sleeping concentrates weight on the shoulders and hips, which can create both pressure points and localized heat. Sapira Chill Hybrid in plush or medium-firm combines contouring foam with zoned coil support to address both at once. 

Couples: Individually wrapped coils in the hybrid models isolate motion to where it originates, so one partner moving or getting up is less likely to disturb the other. Pairing that with the collection's cooling tech helps address mismatched temperature preferences too. 

People with night sweats or hormonal temperature swings: The Ultra Cool Cover's wicking properties and the phase-change materials' buffering effect are designed specifically for sudden temperature changes, not just steady-state warmth. 

Combination sleepers: Oasis Chill Hybrid's contouring and Sapira Chill Hybrid's medium-firm option are built to perform reasonably well across side, back, and stomach positions rather than favoring just one. 

Shoppers who care about materials: Three of the four Chill models are built with GreenFlex® BioFoam, certified under the USDA BioPreferred® Program, and every Leesa mattress is GREENGUARD Gold certified, CertiPUR-US® certified, and fiberglass-free.

How to Choose the Right Chill Mattress 

Step 1 — How hot do you actually sleep? 

  • Wake up hot most nights or deal with night sweats → Sapira Chill Hybrid or Legend Chill Hybrid
  • Sleep warm occasionally, mostly in summer → any Chill model will help; choose based on budget and firmness
  • One partner runs hot, the other doesn't → a hybrid model (better motion isolation keeps one partner's adjustments from disturbing the other)

Step 2 — What's your primary sleep position? 

  • Side sleeper → Sapira Chill Hybrid (plush/medium-firm) or Legend Chill Hybrid
  • Back sleeper → Sapira Chill Hybrid (medium-firm/firm) or Legend Chill Hybrid
  • Stomach sleeper → Sapira Chill Hybrid (firm) or Legend Chill Hybrid
  • Combination sleeper → Sapira Chill Hybrid (medium-firm) or Oasis Chill Hybrid

Step 3 — Budget 

  • Under ~$1,200: Studio Chill Hybrid
  • Mid-range: Sapira Chill Hybrid or Oasis Chill Hybrid
  • Premium: Legend Chill Hybrid

Because pricing changes with frequent sales, and Leesa offers a 120-night trial either way, it's reasonable to prioritize firmness and cooling needs first and let the trial period settle any remaining doubt.

Frequently Asked Questions

Effective cooling combines heat-drawing materials — cooling fibers, gel infusions, phase-change compounds — with airflow-friendly construction like hybrid coil systems, so heat doesn't build up under the body.

Conventional memory foam is closed-cell and dense, which is why it has a reputation for sleeping hot. GreenFlex is open-cell, so air moves through the foam instead of being sealed inside it. In a hybrid, that means airflow through the comfort layers and the coil core rather than just a cool surface on top.

Individually wrapped coils create open space for air to circulate through the mattress core, unlike solid foam, which traps heat within its structure.

Every Chill model includes a 120-night home trial (30-night minimum recommended before returning) and a limited lifetime warranty.

Sapira Chill Hybrid in medium-firm offers zoned support that works for both side and back sleepers; lighter side sleepers may prefer the plush option.

AARP's testing found the Sapira Chill Hybrid retaining about 8 degrees of heat after exposure — a strong result relative to the mattresses AARP has tested, though exact comparisons vary by publication and testing method.

Yes — Chill models work with most standard frames, platform beds, and adjustable bases that provide adequate support.
