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, 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. That 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 a 4.5/5 temperature-regulation score from Tom's Guide
  • — Medium feel delivers strong pressure relief and lower-back support for back sleepers
  • — Flat queen price of $295, well below the premium Helix GlacioTex Premium Topper
Watch-outs
  • — Cooling is good but not best-in-class; one rival reviewer called it strong, not the very best on the market
  • — Cover is not removable for washing, as Tom's Guide notes

ViscoSoft 4-Inch Pillow Top Memory Foam Topper
Ranked #4 in Best Cooling Mattress Toppers
ViscoSoft 4-Inch Pillow Top Memory Foam Topper
2 sources$209.95as of Oct 11

ViscoSoft's 4-inch two-layer topper, sold over time as the Serene Hybrid and the Hybrid Lux, pairs a 1.5-inch down-alternative pillow top with 2.5 inches of gel-infused memory foam. Tom's Guide tested a queen for about a month and rated it 4.5 out of 5, praising pressure relief for side and back sleeping and reporting that its testers never felt hot on it. Sleepopolis scored it 3.9 out of 5 and does not recommend it for hot sleepers, because it has no cooling features beyond the gel foam and the pillow top may trap heat. Both outlets say it is too soft for stomach sleepers.

Strengths
  • — Tom's Guide's testers never felt hot on it, even with the room at 70F to 75F
  • — Pillow-top layer is machine washable, per Tom's Guide and Sleepopolis
  • — 90-day trial and 5-year warranty, per Tom's Guide
Watch-outs
  • — No active cooling features; Sleepopolis says it is not a great option for hot sleepers and that the pillow top may trap heat
  • — Too soft for stomach sleepers, according to both Tom's Guide and Sleepopolis
  • — Tom's Guide found it slipped out of alignment after a few days and needed readjusting about once a week

How they stack up

Saatva Graphite Memory Foam Topper

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

At 4 inches it is the thickest topper on this page, against 3 inches for the Bear Pro Topper and Saatva Graphite Memory Foam Topper and 2 inches for the Layla Copper Memory Foam Topper. It relies on gel-infused foam alone for temperature control, where the Layla uses a copper infusion with a ThermoGEL cover and the Saatva uses a graphite infusion.
