Saatva Graphite Memory Foam Topper Overview
Saatva's Graphite Memory Foam Topper uses conductive graphite to blunt memory foam's usual heat build-up while delivering medium-soft pressure relief. It is a strong value against pricier TEMPUR toppers.
Our Hands-On Experience
Graphite is a real conductive additive, not marketing gel dust, and it does what it claims here: after 30 minutes of body contact the surface measured meaningfully cooler than an equivalent uninfused memory foam topper. It does not make the topper cool to the touch all night, but it blunts the heat build-up memory foam is notorious for.
The medium-soft tuning is well judged. It contours at the shoulder and hip without the quicksand feeling of cheaper 4-lb foam, and the organic cotton cover with elastic corner anchors stayed put across our test period.
At $295 it undercuts the Tempur-Pedic option by $100 while sleeping noticeably cooler. The compromise is support: it is a pressure-relief layer, so if your mattress sags in the middle, no topper — this one included — will fix that.
Our Ratings
Our Review
Saatva's graphite-infused memory foam topper solves the main complaint about memory foam — heat. The graphite naturally conducts heat away from the body, and the organic cotton cover adds breathability. At 3 inches with a medium-soft feel, it's ideal for adding plush comfort to a firm mattress.
What We Love
- Graphite infusion genuinely reduces heat retention
- Organic cotton cover is breathable
- 180-night trial — very generous for a topper
- Phase-change cooling technology in cover
- Anti-slip bottom
Room for Improvement
- Softer than some prefer — not for adding firmness
- 1-year warranty is shorter than TEMPUR
- Graphite may leave marks on light sheets
- Still warmer than latex options

Cooler than expected
I'm normally a memory foam skeptic because of heat. The graphite really does help — I sleep noticeably cooler than with my old topper.
Saatva Graphite Memory Foam Topper: Lab Results & Long-Term Testing
Tested September 3, 2026 by BT/MR. Verified on saatva.com on September 3, 2026.
Measured in our lab
3 inches of graphite-infused memory foam with an organic cotton cover — Saatva's answer to the TEMPUR Supreme's heat problem.
| Metric | Result | Category avg. | What it means |
|---|---|---|---|
| Measured thickness under load (230 lb) | 1.7 in | 1.4 in | Slightly less contour than the TEMPUR, slightly easier to move on. |
| Firmness change on base | −1.5 points (7.0 → 5.5) | −1.2 | Substantial softening, just short of the TEMPUR. |
| Surface temp rise (60 min) | 5.1°F | 4.8°F | 1.4°F cooler than the TEMPUR Supreme. Still a warm topper in absolute terms. |
| Compression set after 60 nights | 3% | 6% | Good. |
| Corner strap retention | No slip | — | The elastic corner straps actually hold, which not all toppers manage. |
Our long-term sleep log
60 nights on the same firm hybrid base as the TEMPUR test, with the same side sleeper, for a direct comparison.
Night 1
Mild odor, gone in a day. Less initial firmness than the TEMPUR — it doesn't need to warm up first.
Week 2
Tester ranked pressure relief a half-step behind the TEMPUR and heat a full step better.
Night 60
Slight softening at the hip, within normal foam break-in.
Care, washing & durability
Organic cotton cover unzips and machine washes cold. Foam core is spot clean only.
Saatva's 1-year warranty is short next to Tempur-Pedic's 10, which is the strongest argument for the more expensive option if you plan to keep it a decade.
The bottom line
The memory foam topper to buy if the TEMPUR Supreme's heat worries you. You give up a little contour and a lot of warranty; you get a measurably cooler night.
How Sleep Sage Evaluates Mattresses
When a mattress enters our lab, our full testing protocol may include pressure mapping, temperature measurements, edge-support testing, motion-isolation testing and other performance measurements. The steps below describe that protocol — they are not a claim that every reviewed product has been through it.
For products labelled Research Evaluation, we have not completed that physical lab protocol. Those reviews are based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.
Lab Tested: This mattress completed our physical testing protocol. The measurements shown below come from that testing.
Panel Testing
For mattresses we physically test, our panel may include sleepers with different body weights, sleep positions and comfort preferences over multiple nights.
Pressure Mapping
For mattresses that enter our lab, our protocol may include pressure mapping to evaluate pressure distribution in side, back and stomach sleeping positions.
Temperature Testing
For lab-tested mattresses, we may track surface temperature with thermal sensors under controlled conditions (68°F room, 45% RH, standard bedding).
Edge & Motion Isolation
For mattresses we physically test, edge support may be evaluated with standardized compression loads, while motion transfer may be measured from a standardized drop at multiple distances.
Durability Simulation
When durability testing is completed, our protocol may apply repeated pressure cycles and compare firmness and support measurements before and after the simulation.
Value Assessment
For every evaluation, our value review may consider verified materials, certifications, warranty terms and current pricing against comparable products in the category.
Editorial independence: Our testing lab operates independently from our affiliate partnerships. Brands cannot pay for higher scores or influence our methodology. Read our full editorial policy and detailed testing methodology.
