Our take on the Casper Essential Mattress Topper

The Casper Essential Mattress Topper is a 3-inch memory foam layer with a quilted soft-knit cover, sold in Twin XL, Full, Queen and King. It is aimed at softening a too-firm mattress and easing pressure points, and Casper lists guest beds and dorms among its uses. The cover is not removable, so it cannot be washed separately. At $78 at Kohl's as of November 6, 2026, it sits well below what a 3-inch foam topper from a major brand usually costs.

Pros
  • 3 inches of foam adds real cushioning
  • Quilted soft-knit cover feels finished, not bare foam
  • Breathable foam design is meant to sleep cooler than dense memory foam
  • Available in Twin XL, Full, Queen and King
  • $78 at Kohl's as of November 6, 2026 is a low entry price for the brand
Cons
  • Cover is not removable, so it cannot be washed
  • Memory foam can sleep warm for hot sleepers
  • 3 inches may feel too soft for stomach sleepers or heavy bodies
  • King size weighs about 27 lbs, so rotating it is awkward
  • Some owners report it compresses over time

Questions and answers

Is $78 a good price for the Casper Essential Mattress Topper?
It is a low price for a 3-inch branded foam topper; comparable Casper toppers usually sell for more. Five stores list it new, so compare before buying if you want a specific size.
Does the cover come off for washing?
No. The quilted soft-knit cover is fixed, so spot clean it and use a mattress protector over it.
Will it make a firm mattress softer?
Yes, that is its main job. Three inches of foam adds cushioning at hips and shoulders, which suits side sleepers most.
Does it sleep hot?
Casper calls the foam breathable, but memory foam still runs warmer than a bare mattress for some sleepers. Hot sleepers should weigh that.
What sizes are available?
Twin XL, Full, Queen and King. Check your mattress size, since Twin XL is 80 inches long and will not fit a standard Twin frame.
How thick is it, and will sheets still fit?
It is 3 inches thick. Deep-pocket sheets usually still fit, but tight sheets may need replacing.
Where is the Casper Essential Mattress Topper cheapest?
At Kohl's, for $78.00, 40% under what the other stores charge, as of our latest check.

Rated 3.8 out of 5 from 88 ratings.
