Our verdict
Where it wins
- 3+ lb density foam holds a flat surface and resists indentations better than lighter toppers
- Adjustable straps and a slip-resistant cover bottom keep it from sliding off the mattress
- Priced identically at Target, Walmart, and ViscoSoft's own site, so there is no guessing where to buy it
- Backed by a 90-day money-back guarantee on top of the multi-year warranty
Where it loses
- Medium-firm feel that some reviewers found too firm straight out of the box
- Denser foam means more weight to wrestle onto the bed alone, especially at King size
- Costs noticeably more than a basic gel topper like the LUCID at the same 3-inch thickness
The ViscoSoft Select High Density topper is built from a denser single block of gel memory foam than most budget toppers, which shows up as steadier edge support and a surface that holds its shape over time. It runs medium-firm rather than plush, so side sleepers who want a deep sink may prefer a softer pick. For anyone whose mattress has gone soft or who wants a topper likely to still be flat in three years, it is a solid step up from the cheapest gel toppers without reaching Tempur-Pedic pricing.

More on the ViscoSoft Select High Density 3" Memory Foam Mattress Topper
Common questions
Is the ViscoSoft topper firm or soft?
ViscoSoft describes it as a medium-firm feel. It contours like memory foam but resists sinking further than lower-density toppers because of its higher density foam.
Does the cover come off for washing?
Yes. The rayon-from-bamboo and polyester cover is removable and machine washable, and it includes adjustable straps to keep it fitted to the mattress.
How is it different from a cheaper 3 lb memory foam topper?
ViscoSoft cuts the topper from a single block of foam rather than a scooped or layered design, which the brand says gives more consistent support across the whole surface, including the edges.
What is the warranty on the ViscoSoft topper?
ViscoSoft's product page lists a 5-year warranty plus a separate 90-day money-back guarantee.
