Ranked #3 in Best Cooling Mattress Toppers

Saatva Graphite Memory Foam Topper

4.5

$305as of Jun 7

The Saatva Graphite Memory Foam Topper is the value-and-trust pick: graphite-infused foam that measurably offsets heat, an 8.6 out of 10 from Sleep Foundation, a 4.7 average from nearly 200 buyers, and an unrivaled 180-night trial. At a flat $295 it cools well, relieves pressure, and supports the lower back, even if it is not the single coolest topper on the market. The long risk-free trial makes it the easiest topper here to buy with confidence.

Strengths

— Graphite-infused memory foam offsets heat retention, earning an 8.6/10 from Sleep Foundation and an 8.4/10 cooling sub-score from Tom's Guide
— Carries a 4.7 average star rating across nearly 200 verified buyer reviews
— Industry-leading 180-night sleep trial with free returns, the longest on this list

Watch-outs

— Cooling is good but not best-in-class; one rival reviewer called it strong, not the very best on the market
— High-density memory foam runs warmer than a phase-change or hybrid design under heavy sleepers
— Medium feel may be too firm for dedicated side sleepers wanting deep cushion

Ranked #4 in Best Cooling Mattress Toppers

ViscoSoft 4-Inch Pillow Top Memory Foam Topper

4.5

$209.95as of Jun 7

The ViscoSoft 4-Inch Pillow Top is the value and plushness pick, with a 4.4 average across more than 12,000 buyer reviews and a Good Housekeeping Best Hybrid Topper award. Its dual-layer design (gel memory foam under a fiberfill pillow top) delivers a hotel-soft surface, while gel-infused foam and a cool-to-the-touch TENCEL cover keep heat and moisture in check. Cooling trails the top picks, but for plush comfort and pressure relief per dollar it is outstanding.

Strengths

— Holds a 4.4 average star rating across more than 12,000 buyer reviews, by far the largest review base here
— Dual-layer build (3 in gel memory foam + 1.5 in fiberfill pillow top) gives a plush, hotel-like surface with strong pressure relief
— Gel-infused foam plus a cool-to-the-touch TENCEL cover regulate heat and wick moisture for hot sleepers

Watch-outs

— Cooling is solid but trails the dedicated graphite, phase-change, and copper designs above it
— Some buyers report firmness softening and durability concerns over time
— At 4 inches thick it can feel like too much sink for back and stomach sleepers

How they stack up

Saatva Graphite Memory Foam Topper

Cools nearly as well as the Bear Pro Topper and Helix GlacioTex Premium Topper while costing less than the Helix GlacioTex Premium Topper, and it pairs that with the longest trial here at 180 nights. Firmer and more supportive than the plush, contouring Layla Copper Memory Foam Topper and ViscoSoft 4-Inch Pillow Top Topper.

ViscoSoft 4-Inch Pillow Top Memory Foam Topper

Plusher and thicker than the Saatva Graphite Topper, with a pillow-top feel the firmer Helix GlacioTex Premium Topper does not offer, and it costs less than both. It cools less effectively than the Bear Pro Topper, Helix GlacioTex Premium Topper, or Saatva Graphite Topper, landing closer to the Layla Copper Memory Foam Topper on temperature.
